How to make the mobile phone transparent? Answer people who know physics!

A key part of the fuselage design is the use of replaceable glass, using conductive technology, in the invisible circuit environment, so that LED light.

This kind of glass contains liquid crystal molecules, and the content is displayed by exciting the molecules with current. When the phone is turned off, the molecular positions will be randomly distributed, showing a milky white appearance.

Double-sided touch

Samsung's new screen patent

Users can control the front and back of the mobile phone with their fingertips, so as to unlock it by touching the back, select programs, drag and capture images and so on.

Touching the front and back of the screen can perform two different functional operations. For example, touching the back can open a folder in the file list, and clicking on the folder can display a preview of the content. In addition, touching the back of the screen can make more information pop up, such as notes and photos. There is no need to display navigation on the front of the screen at all.

Touch operation

Samsung's new screen patent

A patent for transparent screen of mobile phone provides a practical touch operation for future transparent devices, which can open applications or control video playback without affecting users' sight. In other cases, the screen is designed as a multi-layer structure, and then the object is moved and placed on a certain layer.

Transparent battery

In 20 1 1 year, researchers at Stanford University developed a transparent lithium battery. Because the wires connecting the electrodes on the circuit board are only 35 microns thick, they can't be captured by the naked eye. The two circuit boards are connected by transparent lithium battery to form a perfect circuit system. The newly manufactured transparent battery has good power storage capacity. The storage density of lithium manganese oxide can reach 97 mAh per gram, and the capacity of lithium titanium oxide can reach 1.42 mAh per gram. After 40 charge-discharge cycles, the energy storage efficiency can still reach 87% and 93% respectively. However, compared with the traditional opaque lithium-ion battery, the capacity of transparent battery is still insufficient-it can only reach a pitiful capacity of 10 WHr per liter, which is about110 of the traditional lithium-ion battery. However, the theoretical capacity of this new battery is the same as that of the traditional battery. Researchers believe that PDMS substrate and electrode can be made thinner to improve energy storage density, or electrode materials such as lithium cobalt oxide can be used to increase the capacity of the battery to 50 watt-hours per liter. February 20 13, the transparency of this battery has reached 60%, but the battery capacity is still relatively weak.

design feature

Transparent mobile phone

The design features of transparent mobile phones can be summarized as follows:

1, small size. The thickness is about 0.5 cm. Compared with the iPhone5, the screen is 4.3 inches and the weight is 25% lighter.

2, strengthen the fall prevention, even if it falls heavily on the ground, it will not be fragmented.

3, single-sided touch, but can be displayed on both sides.

4. The battery, microphone and microSD card slot are all at the bottom of the mobile phone, and these components are covered because they are temporarily opaque.

Display quality is the most important. If the quality of transparent LCD screen can't meet the quality standards of AMOLED and LCD screen, there will be no mobile phone sales using it, even though it is a novel material. (Avi Greengart, Director of Market Research, Current Analysis)
