Compared with LCD display, the LCD display has the advantages of high brightness, full color, high contrast, lower driving voltage, faster response time and the like. The AMOLED display screen also gradually comes into the market, and tends to replace the conventional LCD display. As a next generation display technology, AMOLED display has a good development prospect. However, the AMOLED display technology still has significant drawbacks. Because the luminance of the OLED device changes with the temperature change, when the ambient temperature changes, the driving condition of the OLED panel needs to be changed to compensate the luminance, so as to offset the luminance drift caused by the temperature change, thereby adapting the display panel to different ambient temperatures.
The light emitting temperature of the existing silicon-based OLED can be detected by a temperature sensor inside the IC, and thus a temperature compensation scheme is already integrated inside the IC of the silicon-based OLED. Due to the characteristics of the OLED device, the luminance of the OLED device changes with temperature, and as shown in fig. 5, if the luminance of the display device needs to be stabilized at different temperatures, temperature compensation needs to be performed on the display system. Fig. 3 is a Temperature Compensation structure in a conventional OLED display system, where an ambient Temperature is monitored by a Temperature Sensor (Temperature Sensor), the Temperature is stored in a Temperature Register (Temperature Register), after a Controller (Controller) reads the Temperature from the Temperature Register, the Temperature Compensation Look-Up Table (Temperature Compensation Look-Up-Table) is referenced to calculate a variation of a display system driving Voltage, and then the Voltage driving module (Voltage Driver) is controlled to make a corresponding adjustment, so as to change the brightness of the display system, where the Compensation process is shown in fig. 4.
