1, technical difference
IPS: (In-plane switching) technology was first invented by Hitachi, which is also commonly known as hard screen. It is hard because the liquid crystal molecules rotate parallel to the glass surface (while the soft screen rotates perpendicular to the glass surface, which is later). Generally, there are 6~7 TFT processes, and the details in the screens made by different companies are a little different.
MVA: full name (Multi Vertical Alignment), multi-quadrant vertical alignment technology, is a patent registered by Fujitsu, and now most panel factories in Taiwan Province Province are like this. The purpose is to make a compromise between TN and IPS, and its principle is to increase protrusions to form multiple visual areas.
2, the difference between manufacturers' research and development.
IPS: (In-plane switching) technology was first invented by Hitachi.
MVA (Multi-domain Vertical Arrangement) was developed by Fujitsu in 1998.
3, the area on the pixel
IPS, commonly known as hard screen, has high viewing angle, fast response, accurate color reproduction and moderate price. The disadvantage is that it is easy to leak light and the purity of black is not enough.
MVA panel has the advantages of slow response, the highest viewing angle, high color reproduction and high price. The disadvantage is that there is color drift, and the display effect is not very good on sharp words (words that are not obvious in normal office).
Extended data:
Type of computer display screen:
1, CRT display, CRT (cathode ray tube) is a cathode ray tube. This is a widely used display technology. The CRT projector decomposes the input signal source into the fluorescent screens of three CRT tubes: R (red), G (green) and B (blue). Under the action of high voltage, the luminous signals are amplified and converged, and color images are displayed on the big screen.
2.LCD display, LCD (liquid crystal display), usually called "liquid crystal flat panel display" or "liquid crystal display" in Chinese. Its working principle is to use the physical characteristics of liquid crystal: after electrifying, the arrangement becomes orderly, which is convenient for light to pass through; When there is no electricity, the arrangement is chaotic, which hinders the passage of light. Simply put, let the liquid crystal block or let the light pass like a gate.
3, projector, DLP is the abbreviation of English Digital Light Porsessor, translated into digital optical processor. The birth of this new projection technology enables us to display digital information after having the ability to capture, receive and store it.
DLP technology is an epoch-making revolution in the display field. Just as CD has a great influence in the audio field, DLP will turn a new page for video projection display. It uses DMD (digital micromirror device) digital micromirror as the imaging device of light valve.
