LCD panel can show the number of colors

In the purchase of Graphic LCD Display TV, in addition to often see the screen size, resolution, brightness, contrast, response time specification parameters, often we will find that there is a word called "Colors." Different brands and models of LCD TVs for the description of the number of different colors, the corresponding figure is night and day to another, some marked only 16.7 million, some labeled as 1 billion, as well as a more exaggerated marked as 28.9 billion. So, what these numbers represent what the meaning behind its products can reflect much difference between it?
 
LCD TV can show a number of colors by what factors determine it?

First, we have to be cognizant of two completely different concepts, one is the LCD panel can show the number of colors, an internal circuit is capable of handling the number of colors, both of which are related to the lcd modules TV can be displayed delicate color gradation extent.

LCD panel can show the number of colors

LCD panel can be expressed by the number of colors inherent physical characteristics of the panel decision. According to the basic principle of the liquid crystal display image, the liquid crystal molecules by two glass substrates attached to the upper and lower driving voltage between the occurrence of the corresponding deflection angle, the light through the liquid crystal layer when the angular deflection according to the size of the liquid crystal to obtain different levels of transmission, the This is reflected in the panel have different levels of gray scale contrast. When light passes through the liquid crystal layer needs through the filter, the filter corresponding to each pixel is divided into red, green, and blue small squares, the original white light from these small squares separated out after filtration , the entire panel can present a variety of colors, which is colorful screen display panel simple principle.

LCD driving principle


The liquid crystal panel of the full color image forming process
From the above description it can be seen, the panel can be expressed by the number of colors of the liquid crystal drive deflection angle of the degree of sensitivity. Assuming deflection voltage variation and LCD is divided into 256 steps, then when the voltage generating a step change in the liquid crystal along the angle of deflection of an order, so the panel can show a color change of order; However, if the voltage to produce a step change When the liquid crystal molecules did not produce a corresponding first-order angular deflection, then no one step on the performance of the panel color changes.

Therefore,OLED Module  there is a liquid crystal panel, the number of colors can be expressed concept, which is determined by the panel of the innate physical properties. As in the display people tend to care about what is TN panel or a VA panel, largely because TN panels can be demonstrated by the number of colors as rich VA panel, showing a level of less than VA panel screen delicate vivid. Of course, the above description is idealized assumption, I just hope that this can be expressed in a more intuitive and easier to describe the problem.
