How important is the TV LCD panel, Sharp's spread of things

If you choose a TV today, if it is a LCD TV, the panel is still the most important link affecting the quality of the TV. The quality of the TV panel is directly determined by the quality of the panel. Recently, the industry has become increasingly rampant because of the TV panel's ownership. Ms. Jiang sued Sharp for the non-Japanese origin of the 45-inch smart TV purchased at Sharp Mall. Sharp then responded at Weibo. The 45-inch LCD was sold at a Japanese factory. It was definitely a "Japanese original panel." Mixed audiovisual. Is an LCD panel really important?

As we all know, the Big Butt TV - CRT TV has no panel to say, the panel battle is starting from the LCD era. According to the imaging principle of LCD TVs, we will be able to regard the processor, backlight and LCD panel as the three key points that affect the image quality.

Liquid crystal is an organic compound between a solid and a liquid, and it is in a liquid state under normal conditions, but it exhibits the same arrangement rules as a solid crystal. When an electric field is applied to the liquid crystal molecules, the liquid crystal molecules can be twisted. Under the polarizer, the liquid crystal molecules have the function of blocking the passage of light, so long as the liquid crystal molecules are enough, the images can be displayed in a lattice manner. If the color filter is used, it is generally an RGB primary color filter. By controlling the degree of twisting of the liquid crystal molecules with different voltages, it is possible to change the transmittance of a certain primary color. Just controlling the amount of transmitted light of each primary color can achieve color display.

The liquid crystal panel injects a large number of liquid crystal molecules arranged in a regular manner between two glass plates, and adds a driving circuit for driving liquid crystal torsion, and is divided into different types of panels such as TN, VA, and IPS depending on the arrangement of the liquid crystal molecules, and the panel types have different performances. Differently, IPS is currently the most common type of TV, monitor, and mobile phone.

It can be seen that the LCD panel is the most critical part of the TV. It directly determines the fluency, contrast, physical clarity, size, and viewing angle of the TV picture, and affects the color saturation to some extent. The faster the twisting speed of the liquid crystal molecules in the liquid crystal panel, the faster the response speed of the panel and the better the fluency, the TN panel is the easiest to realize a high response speed; the more pixels made of liquid crystal molecules, the higher the resolution and the better the physical clarity. Liquid crystal molecular arrangement means that the panel structure directly determines the viewing angle and contrast, TN is the worst, IPS and VA have similar performance; the higher the twisting accuracy of the liquid crystal molecules, that is, the higher the number of bits (8 bit, 10 bit) of the liquid crystal panel, The richer the color performance, IPS and VA are more suitable for achieving high bit numbers. Therefore, the panel determines the picture quality of LCD TVs. Most LCD TVs today use IPS and VA panels.

At present, there are no recent developments in this incident. Focusing on the 45-inch TV production area that consumers are concerned about, Sharp reiterated that it welcomes supervision of Sharp TVs. At the same time, as a 105-year-old company, Sharp always puts consumers’ interests In the first place, Sharp will continue to adhere to this concept and continue to serve the majority of Chinese consumers.
