As we all know, big ass TV -CRT TV has no panels, and the panel disputes start from the LCD era. According to the imaging principle of LCD TVs, we will be able to regard the processor, backlight and LCD panels are the three key points that affect the quality of the picture quality.
LCD is an organic compound between the solid and liquid. It is liquid state in normal conditions, but it shows a solid crystal -like arrangement rule. When an electric field is applied to the LCD molecule, the LCD molecule can be reversed. With the polarizer, the liquid crystal molecule has the effect of blocking the passing of light. As long as the LCD molecules can display the image in a dot matrix. If the color filter is matched, it is generally the RGB triangular color filter. With different voltage control the degree of liquid crystal molecule to reverse, it can change the amount of light transmission rate of a certain primary color.
LCD panels are liquid crystal molecules arranged in a certain rules between two pieces of glass, and add driving circuits that drive LCD reversing. Different types of panels such as TN, VA, IPS are divided into different types of panels such as LCD molecular arrangement. Different, IPS is currently the most common type of TV, display, and mobile phones.
It can be seen that the LCD panel is the most critical part of the TV. It directly determines the smoothness, contrast, physical clarity, size, and visual angle of the TV picture quality, which affects color saturation to a certain extent. The faster the liquid crystal molecule in the LCD panel, the faster the response speed of that panel, the better the fluency, and the easiest to achieve high response speed for the TN panel; the more pixels composed of LCD molecules ; LCD molecular arrangement method, that is, the panel structure directly determines the visual angle, contrast, TN is the worst, IPS and VA are similar; the higher the torsional accuracy of the liquid crystal molecule, the higher the number of LCD panels (8bit, 10bit). The richer the color performance, the higher the IPS and VA are more suitable for achieving high bit. Therefore, the panel determines the height of the quality of the LCD TV. Today, most LCD TVs use IPS and VA panels.
