11.6 inch tft lcd display manufacturers take you to understand how TFT works


11.6 inch tft lcd display manufacturers tell you that TFT generally refers to thin-film liquid crystal displays, but actually refers to thin-film transistors (matrix) - which can "actively" control each independent pixel on the screen, which is also called The origin of the active matrix TFT.

So how did the image come about? The basic principle is very simple: the display screen is composed of many pixels that can emit light of any color, and the goal can be achieved by controlling each pixel to display the corresponding color. 11.6 inch tft lcd display manufacturers tell you that backlight technology is generally used in TFT LCD. In order to accurately control the color and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the "blind" is opened When the light can pass through, the light cannot pass through when the "blinds" are closed. Of course, the technical implementation is actually not as simple as just said. LCD uses the characteristics of liquid crystals (liquid when heated, and solid when cooled). Generally, liquid crystals have three forms: smectic liquid crystals similar to clay, filamentous liquid crystals similar to thin matchsticks, and cholesterol-like liquid crystals.
The 11.6 inch tft lcd display manufacturer tells you that the liquid crystal display is filamentary, and its molecular structure will also change when the external environment changes, so that it has different physical properties - it can achieve the purpose of allowing light to pass through or blocking light - also Just like the shutters.
We all know the three primary colors, so each pixel on the display screen needs to be composed of three similar basic components described above, which control the three colors of red, green and blue respectively.
11.6 inch tft lcd display manufacturers tell you that the most common one is twisted nematic TFT liquid crystal display. Existing technologies vary widely.
There are grooves on the upper and lower layers, wherein the grooves of the upper layer are arranged longitudinally and the lower layer is arranged laterally. When the liquid crystal without voltage is in a natural state, after the light emitted from the light emitting layer passes through the interlayer, it will be twisted by 90 degrees, so that it can smoothly pass through the lower layer.
The 11.6 inch tft lcd display manufacturer tells you that when a voltage is applied between the two layers, an electric field is generated, and the liquid crystals are aligned vertically, so the light does not twist - the result is that the light cannot pass through the lower layer.
