LCD display manufacturer.Is LCD still brilliant? Liquid crystal display (Liquid Crystal Display, LCD) is a kind of flat panel display technology (Flat Panel Display, FPD), based on the special physicochemical and optoelectronic properties of liquid crystal materials.
At present, the most mature and widely used display devices in flat panel display technology are mainly used in televisions, displays, notebooks, tablets, smartphones and other fields.
At present, the so-called LCD in the market mainly refers to the active matrix thin film transistor liquid crystal display (Thin Film Transistor LCD, TFT-LCD), including thin film transistor (TFT) and liquid crystal display (LCD) technology, that is, liquid crystal display controlled by thin film transistor.
The liquid crystal display screen is constructed like a sandwich, with liquid crystal interspersed between two glass substrates, namely TFT Array glass and a colored filter. There are countless pixel arrangements on TFT Array glass, and color filter is an important source of picture color, liquid crystal is interspersed between TFT Array and color filter.
When the voltage is in the TFT (transistor), the liquid crystal turns, and the light passes through the liquid crystal to produce a pixel on the panel, and this light source is provided by the backlight module. At this point, the color filter gives each pixel a specific color. The final result of the combination of each pixel of different colors is the image at the front of the panel.
TFT-LCD must be produced through more than 300 processes in a precision clean room. The highest cleanliness level of a clean room can reach “10” (that is, in a clean room environment, there are no more than 10 dust per cubic foot).
The Array process in the front part is similar to the semiconductor process, but the difference is that thin-film transistors are made on glass rather than silicon wafers.
In the middle section of Cell, the TFT Array glass in the front section is used as the substrate, combined with the colored filter glass substrate, and liquid crystal is dripped between the two glass substrates, and then the large pieces of glass are cut into panels.
The assembly process of the rear module is the assembly and production of glass and other components such as circuits, frames, backlights and so on after the Cell process.
The factory of TFT-LCD has evolved from the previous first-generation factory to the current 11th-generation factory. The difference between each generation lies in the size of the glass substrate. The larger the glass substrate, the larger the panel can be cut.
Precision linear motor platforms are widely used in semiconductor and 3C fields, including panel industry, integrated circuit industry, wafer testing technology, etc., in which panel industry equipment includes Mini LED Micro LED precision platform and equipment, touch screen ITO silver paste etching, FPD glass testing platform, touch screen OGS laser direct writing platform, LCD TFT-LCD panel testing platform, comprehensive screen high-speed double-sided cutting platform and so on.
