A lawsuit brought Sharp to the top of the storm. Ms. Jiang accused Sharp of buying 45-inch smart TV in Sharp Mall because it was not Japanese origin. Sharp then responded on microblog that the 45-inch LCD sold in Sharp Mall came from Japan's Sai factory. It was absolutely "Japanese original panel" and considered that individual people mixed food and audio-visual.
Sharp LCD-60SU770A TV, Japanese original panel, but the whole machine is produced in Nanjing
Today electronic MADE IN CHINA is a normal way, such as the iPhone, Surface Book, Panasonic GH5 are all made in China, but many parts are still imported, especially CPU, high-end screen, so Sharp will put forward the slogan of "Japanese original panel". But the propaganda belongs to propaganda. How much influence does the panel have on the quality of today's TV pictures?

LCD Panel for Determining Picture Height
It is well known that CRT TV, a big butt TV, has no panel. The panel dispute began in the age of LCD. According to the imaging principle of LCD TV, we can see that processor, backlight and LCD panel are the three key points that affect the quality of picture.
Liquid crystal is a kind of organic compound between solid and liquid, which is in liquid state under normal conditions, but presents the same arrangement rules as solid crystal. When an electric field is applied to the liquid crystal molecule, it can twist the liquid crystal molecule. With the polarizer, the liquid crystal molecule can block the passage of light. As long as there are enough liquid crystal molecule, the image can be displayed in lattice mode. If a color filter is used, usually RGB tricolor filter, and the twist degree of liquid crystal molecule is controlled by different voltage, the transmittance of one primary color can be changed. As long as the transmittance of each primary color is controlled, the color display can be realized.

The liquid crystal panel is to inject a large number of liquid crystal molecules in a regular arrangement between two pieces of glass, and add a driving circuit to drive the reverse of liquid crystal. According to the different arrangement of liquid crystal molecules, it can be divided into TN, VA, IPS and other different types of panels. The different types of panels have different performances. At present, IPS is the most common one in TV, display and mobile phones. See the type.
Visible LCD panel is one of the most important components of TV. It directly determines the fluency, contrast, physical clarity, size and visual angle of TV picture quality, and affects the color saturation to a certain extent. The faster the liquid crystal molecule twisting speed in the liquid crystal panel, the faster the response speed and the better the fluency of the panel, the easier the TN panel to achieve high response speed; the more pixels the liquid crystal molecule constitutes, the higher the resolution, the better the physical clarity; the liquid crystal molecule arrangement means that the panel structure directly determines the visual angle and contrast. TN is the worst, IPS and VA are similar; the higher the torsion accuracy of liquid crystal molecules, that is, the higher the number of bits (8 bits, 10 bits) of liquid crystal panel, the richer the color performance, IPS and VA are more suitable for achieving high bit number. Therefore, the panel determines the height of LCD TV picture quality. Today, most LCD TV uses IPS and VA panel.
