What is the driver ic chip (LCD screen, LCM, module manufacturers)

What is the driver ic chip? (LCD mobile mobile phone LCD screen screen, LCM, module manufacturer) Driving method: the adjustment method of using the current value The adjustment method of the pulse amplitude modulation technology The adjustment method of the current value is mainly to change the brightness of the current value adjustment, here it is assumed When the luminosity is 1 times, the luminosity of white light becomes 1.7 times when the current changes, and the luminosity at this time becomes 3 times. Although the illuminance and the current value are not proportional, but the red light is proportional. The main reason It is caused by the fact that the physical properties of the red, green, and blue chips are different from each other. The working principle of the ed driver ic: the chip contains a constant current generating circuit, and the output constant current value can be set through an external resistor. The switching time of the output channel can be controlled through the enabling terminal of the chip, and the switching frequency can be as high as one megahertz (1MHz). The current output responds extremely fast, supporting applications with high color-level changes and high screen refresh rates. Built-in open-circuit detection, overheating power-off, and over-current protection functions greatly improve the reliability of the application system. Driver IC: LED is a light-emitting diode. When the number of diodes is large or the tube consumes a lot of power, it needs to be driven, and it is driven by several levels. If these levels are driven into an integrated electronic chip, this chip is called Simply put, the driver IC plays the role of providing compensation current to the diode.
