What material is the mobile phone screen made of

Mobile phone screens are divided into LCD screens and OLED screens.

The screen material can be divided into: TFT screen, IPS screen, NOVA screen, AMOLED screen, etc., no matter what screen material is used, it needs to be tested before application.

Mobile phone screen testing requires the transmission of current and signal, and the shrapnel micro-needle module can be used as a medium.

When transmitting large current, 50A current can be passed, and it has good overcurrent capability. Small spacing test, can handle 0.15-0.4mm spacing value, stable connection, no pins, shrapnel micro-targeting mobile phone screen test module and reliable performance.

1) TFT LCD screen adopts a combination of “back through” and “reflection”. A special lamp is set on the back of the LCD. The liquid crystal is equipped with a semiconductor switch for each pixel.

The processing technology is similar to a large-scale integrated circuit.

This design not only improves the response speed of the display, but also can accurately control the display gray level, making the color of the TFT liquid crystal more realistic, the display effect is the best, the contrast is the strongest, the visual effect is better, and the power consumption is also the largest.

The characteristics of high contrast, high response, wide viewing angle, and large capacity display make TFT almost the most perfect LCD product at present. Therefore, TFT screens are generally used in high-end mobile phones.

2) IPS screen is an extension of LCD. Relatively speaking, IPS is more purely a kind of panel.

The biggest feature of the IPS panel is that its two poles are on the same surface, unlike other liquid crystal mode electrodes which are arranged up and down in three dimensions.

Under the action of external force, the solidity and stability of the liquid crystal molecular structure of the hard screen is much better than that of the soft screen, so there will be no picture distortion that affects the color of the picture, and the picture effect can be protected to the greatest extent from being damaged.

The technical principle of IPS determines that it can provide faster response speed, and the light leakage phenomenon when the screen is pressed is less than that of VA liquid crystal, so it is more suitable for manufacturing touch screens. IPS screen has the characteristics of low power consumption, high light transmittance, high brightness, fast response, no color shift, and high color reproduction.

3) NOVA is actually a screen display technology. The NOVA screen is also called a high-brightness display. It is a technology based on IPS to improve screen brightness.

The NOVA display has a higher brightness level and pure white tone, which can accurately display black and white primary colors to optimize the reading experience.

After being applied to the product, the mobile phone screen can present a clear display effect regardless of indoor light or outdoor strong light.

In addition, in the same indoor environment, NOVA display can reduce energy consumption by 50% compared to ordinary LCD screens.

4) AMOLED is an active matrix organic light emitting diode panel.

Compared with traditional liquid crystal panels, AMOLED has the advantages of fast response speed, self-illumination, excellent display effect, lower power consumption, etc., and at the same time has faster response speed, higher contrast, and wider viewing angle.

AMOLED uses active light-emitting technology. In layman’s terms, in addition to the function of displaying colors, every pixel on the screen actually has the characteristic of self-luminescence, so that it will not appear on the screen under any background. All pixels are emitting light, and the pixels in the pure black area not only do not display but also do not emit light, which greatly saves power.

At the same time, it also has a good protective effect on the mobile phone screen.
