Although LCD TV and LCD are both output display devices, the core components are also LCD panels, and the interface configuration and appearance design are quite similar, but these two types of products are absolutely distinct and irrelevant in the market.
First of all, in terms of channels, LCD TVs are mostly sold in home appliance stores, supermarkets and other stores, and monitors are sold in IT stores, such as Zhongguancun Hailong and Dinghao. Secondly, consumers will never be confused in use. Few people talk about buying a monitor to watch TV at home, or buying a TV and picking up a computer as a monitor to chat online. Analysis of Eight Differences: Can LCD TV be used as a PC monitor?
So, what's the difference between LCD TV and LCD monitor? What causes so many similar products to have completely different market channels and completely different ways of use? Below, let's analyze them one by one.
LCD TV products are classified as household appliances, and LCD monitors are classified as computer accessories.
The TV can be used directly when you take it home and connect it to the TV, but the LCD should be matched with the host. So one is home appliances and the other is accessories, which makes the sales channels of the two completely different, one is in home appliance stores or supermarkets, and the other is in IT stores.
The difference between more than 30 inches and less than 30 inches
Another obvious difference between LCD TV and LCD monitor is the size difference. The mainstream LCD TV is 32 inches minimum, then 37 inches, 40 inches, 42 inches, until more than 50 inches; For liquid crystal displays, the mainstream size is below 24 inches, and even 17 inches and 19 inches still have a lot of shipments. The largest LCD monitors on the market are only 30-inch Samsung 305T and Dell 3008WFP, but there is still a gap of two inches from the entry-level specifications of 32-inch LCD TVs.
The main reason for this difference is that they are used in different ways. Television is used to watch dynamic images. Put it on the TV cabinet, and the appropriate viewing distance should be at least 3 meters. With the increase of TV size, this distance can be increased continuously. For example, the suitable viewing distance of a 50-inch TV is more than 5 meters. Therefore, TV is not afraid of being big, just widen the viewing distance.
The monitor is completely different. It is mainly used to see static pictures and involves some smaller fonts. Generally, the distance between users' eyes and the screen will not exceed 1 m, while the mainstream use distance is 80 cm, and some users are even used to watching from 0.3 m to 0.5 m at close range. Such a close use distance directly leads to the fact that the bigger the display screen, the better. The 30-inch large screen is already the limit size of the current display. Resolution and point distance are two times different.
At present, the mainstream resolutions of LCD TVs are 1366*768 and 1920* 1080. Even a 55-inch TV has only 1920* 1080. The resolution of LCD is much higher. 2 1.5 inch widescreen resolution is 1920* 1080, and mainstream 22 inch resolution is 1680* 1050. It can be seen that the resolution of the same size screen is much higher than that of LCD TV.
Take 30-inch LCD monitors and 32-inch LCD TVs with similar screen sizes as examples. The resolution of 30-inch LCD is 2560* 1600, and the dot pitch is 0.254; The mainstream 32-inch LCD TV is 1366*768, and the pitch is 0.5 185mm. The size difference is only 2 inches, and the resolution and point distance are about twice as different.
This means that if the above two products are connected to a PC at the same time, the display will display twice as much content (single screen) as the TV, and the font of the display will be smaller and the image display will be more delicate.
This gap is also related to the different usage patterns of the two. At present, the mainstream of domestic TV signal standard (TV system) is PAL system, which stipulates 625 lines of horizontal scanning. So according to this standard, the resolution of 1366*768 is already for TV. ......
How to distinguish the panel types of LCD TV
Samsung (S-LCD) LCD panel S-LCD is a LCD panel factory jointly invested by South Korea's Samsung and Japan's Sony, which mainly produces PVA (patterned vertical arrangement) LCD panels. PVA is an image vertical adjustment technology, which directly changes the structure of the liquid crystal box and greatly improves the display efficiency. The viewing angle can reach 170 degrees, and the response time can be within 25ms. When overdrive is used to accelerate the response time of the screen, the gray-scale response time can also reach the contrast of 8ms, 500: 1 and the color reproduction ability of 70%. At present, S-PVA panel is developed on the basis of PVA panel. The characteristics of S-PVA screen are obvious. When observing red, blue, green or some dark variegated pictures, if you carefully observe each pixel with naked eyes, you will find that the shape of the pixel is >, which is a typical S-PVA screen, and the opening direction of the pixel is also opposite. LG- Philips (LPL) LCD panel The LCD panel produced by LG- Philips LCD Factory, a joint venture between LG of Korea and Philips of the Netherlands, is LPL(LG. Philips LCD) LCD panel mainly adopts S-IPS technology. IPS panel was introduced by Hitachi on 200 1. Technically, the viewing angle is improved by liquid crystal molecular plane switching. Because there is no compensation film on the upper panel, the screen is more transparent and the color is more delicate, but the slow response time and the difficulty in improving the contrast are the big problems that restrict the popularization of this type of panel. S-IPS is actually the second generation IPS technology, and some new technologies are introduced to improve the gray inversion phenomenon of IPS mode at some specific angles. The characteristic of S-IPS screen is that pixels look like.
What does the TV panel type mean?
Liquid crystal, plasma
What's the difference between the panel and screen of LCD TV?
Hehe, then I'll give you a popular answer. The panel is a material screen or a screen LCD screen, which can be directly or indirectly seen by naked eyes. The eyes see the LCD panel through the auxiliary material.
What kind of panel is better for LCD TV?
The following are several mainstream LCD screens: TN panels are mostly used in computer LCD monitors, with low viewing angle, exaggerated colors and easy color cast. However, due to its fast molecular deflection speed, it can reach a response speed of 2MS, which is good for computer monitors and playing games. As for LCD TVs, TN screens are rarely used. The biggest selling point of IPS (in-plane switching plane control mode) wide viewing angle technology (hard screen) is that its two poles are on the same plane, unlike other liquid crystal modes, where the electrodes are arranged vertically. Because the electrodes are on the same plane, liquid crystal molecules are parallel to the screen in any state, which will reduce the aperture ratio and light transmittance, so IPS applications in LCD TVs will need more backlights. Its reduced black color is slightly worse than PVA, and it needs to be compensated by optical film to achieve better black color. Another feature of IPS mode LCD is that when viewed at a 45-degree oblique angle, it will see a gray inversion phenomenon similar to TN mode, which can be used as a sign to distinguish IPS. IPS also has the disadvantages of slow response time and difficult contrast improvement. (S-IPS and AS-IPS are improved IPS technologies) S-PVA and Samsung screen S-PVA are the upgrade technologies of PVA, which is the abbreviation of Patterned Vertical Alignment, meaning the vertical adjustment technology of images, and is the exclusive patent of Samsung. The principle is that when the liquid crystal molecule is stationary, it changes from the traditional vertical to a certain angle, so that when the voltage is applied, the reaction time of the liquid crystal molecule changing into a horizontal state becomes shorter, and its response time can reach more than 8ms. At the same time, because of changing the arrangement of liquid crystal molecules, the contrast and viewing angle are greatly improved. Sony is currently using this kind of screen. Samsung Half-Pixel Grading Screen In the 7th generation screen of Samsung, there is a half-pixel grading display screen. According to the official explanation, a half pixel is called "dividing a sub-pixel into two sub-pixels". One pixel of LCD TV is composed of three pixels: R, G and B, while the S-PVA panel with half-pixel hierarchical display is divided into two "half-pixels". When the signal voltage of the image displayed on the control panel exceeds 50%, the whole pixel emits light, and when it is lower than 50%, one of them can be controlled to turn off, and the other emits light through these two half pixels. Compared with the ordinary LCD panel, the "half-pixel" is ">" shaped, which is very obvious when viewed at close range in front of the screen and easy to judge. Half-pixel display panel is Samsung's exclusive patent technology, which can improve the details and contrast of the picture and make the color level richer and more realistic. CPA (Continuous Windmill Alignment) mode wide viewing angle technology (soft screen), CPA mode wide viewing angle technology is strictly a member of VA camp. Each liquid crystal molecule is arranged in the shape of radioactive fireworks towards the central electrode. Because the electric field on the pixel electrode changes continuously, this wide viewing angle mode is called "continuous fireworks arrangement" mode. CPA is mainly promoted by Sharp, the "father of LCD". It should be noted here that ASV promoted by Sharp does not actually refer to a specific wide-angle technology. Refers to the products that adopt TN+ film, VA and CPA wide-angle technology as ASV. In fact, only CPA mode is Sharp's own wide-angle technology, and the products are basically the same as MVA and PVA. That is to say, Sharp's brand LCD TV does not necessarily adopt Sharp's own CPA mode LCD panel, but may adopt VA mode panel of Taiwan Province Province or LCD panels of other manufacturers. IPSA recommends LG H45 series H50 series Philips 9509 series 5609 series Panasonic 80 series 800 series (Panasonic LCD is 42 inches at most) S-PVA recommends Samsung B750 series B7000 series or cost-effective B620 series CPA recommends Sharp RX 1 series GE50A series E66 series.

What panel does Sony's LCD TV use?
In the CRT era, Sony dominated the color TV market with the "Telilon" technology bought from Americans, and achieved impressive results. However, it is precisely because of indulging in brilliant achievements that nothing can replace Telilong in CRT era! I didn't wake up to the arrival of LCD era in time, so I didn't master the core technology of LCD screen, so I had to jointly produce LCD screen with Samsung. But the technology of LCD screen is still mainly in Samsung's hands! At present, Samsung and Sony use the same LCD screen for their high-end products. However, it can never be said to be Sony's own screen. Of course, Sony's technology in video processing and electronic circuits is still quite strong, and Sony bravia series is still a high-end product in the market. It performed quite well in all aspects. At present, there are more than 20 flat-panel TV brands on the market, and what screen to use is an important selling point. Take LCD TV as an example, almost all brands are playing the brand of seven-generation screen, from Sony's Boda Shen Jing to Xoceco and other domestic products, with seven-generation screen as their selling point. However, just making a fuss on the screen is very limited for the brand and makes users feel a bit homogeneous. The reason why users feel this way is because there are limited companies that can produce LCD and plasma panels at present, and there are only a few brands of screens used by each brand. The top four LCD panels are LGL (a joint venture between LG and Philips), Samsung, AUO and Chimei in Taiwan Province, China, and Sharp ranks fifth with a market share of 6.6%. In terms of plasma, only Samsung, LG, Panasonic, Hitachi and Pioneer can provide it.
In LCD TV, what does "LCD panel: A+" mean? How is it different from other panels?
Quality grade of LCD panel,
A-level screen is higher than B-level screen and C-level screen is the lowest. In addition to these three levels, there is also a name called "super A level" or "AA level", that is, products slightly higher than A level. Generally speaking, both Grade B and Grade C are considered inferior products. Compared with A-class, B-class and C-class have more bad points, relatively uneven brightness, and the appearance may be damaged. The price gap with A-class screens may be as high as nearly 1,000 yuan.
What panel LCD TV is good?
Sharp mainly promotes soft screen, LG mainly promotes IPS hard screen. In fact, in terms of display effect, the level is similar, but the technology used is different. Many domestic brands claim to use Sharp screen, LG screen or Samsung screen, but few of them really use it, and most of them still use Taiwan Province screen. Because non-professionals can't tell the difference at all, they dare to publicize it in a big way.
The LCD technology was first invented by people in Taiwan Province province, but it was carried forward by devils and sticks. Now even Sharp, LG or Samsung's low-end TVs use Taiwan Province provincial screens. Why, in order to save money, if you really pursue quality when choosing TV, don't choose low-end products easily. The joint venture brand TV with a slightly higher price is still trustworthy ... hope to adopt it! !
