One pixel electrode is directly connected to the drain D of the field effect tube, and the other pixel electrode is connected to a certain potential of the driving power supply (on the common electrode, and then the gate G of the field effect tube is used as the selection control terminal of the pixel. The source S is used as the data writing terminal to construct the drive circuit of the TFT Module. Only a liquid crystal pixel model is drawn in the figure, and the capacitance CLC of the pixel is not drawn Passive Matrix Oled.
In fact, the two are the same because the liquid crystal material has capacity load characteristics. When building the drive circuit model of the TFT Liquid Crystal Display, the equivalent of the liquid crystal pixel can not only be used as a capacitor CLC, but also can draw a pixel. TFT module display image process
The grid G of the TFT field effect tube is directly connected to the scan selection signal of the driving driver, which is controlled by the driver. The source of the TFT field effect tube will be connected to the output of the DAC (digital/analog) converter Organic Light-Emitting Diode Display.
In fact, the output of the DAC converter is an analog voltage, which serves as the analog drive voltage for the display pixels. When selecting a certain pixel, apply a forward conduction voltage to the gate G of the TFT field effect tube to make the field effect tube enter the conduction state, and at the same time display the data through the converter of the DAC, and then add the source S of the TFT field effect tube , Through the turned-on TFT field effect tube, and then reach the drain D of the TFT, an electric field is formed while the pixel is displayed, and the liquid crystal material is charged, and finally the display effect is achieved. TFT module display image process
When the gate voltage is removed, the field effect tube of the TFT is turned off and enters an off state. The turn-off resistance Roff of the field effect tube is very large, and combined with the equivalent capacitor and storage capacitor in the liquid crystal material, a relatively large discharge time constant T=RoffXC is formed. The display effect remains for a long time 0.42-1.3 Inch OLED.
The analog driving voltage can be stored on the liquid crystal layer to make it work stably. The driving voltage can also be rewritten in a short time by the TFT module to meet its image quality requirements OLED Microdisplay.
