Description

[technical field] [0001] The invention relates to the technical field of driving circuits, in particular to a Micro-OLED microdisplay driving circuit which has strong applicability and can greatly reduce hardware costs. [Background technique] [0002] As we all know, silicon-based OLED micro-display device organic light-emitting diode micro-display technology (Micro-OLED) is an OLED display device made of single crystal silicon as an active driving backplane; compared with ordinary OLED display devices with glass as a backplane, Micro-OLED -OLED microdisplay devices use monocrystalline silicon wafers (Wafer) as the backplane. In addition to the characteristics of OLED self-luminescence, thin thickness, light weight, large viewing angle, short response time, and high luminous efficiency, it is easier to achieve high PPI (pixel Density, its pixels are 1 / 10 of traditional display devices), small size, easy to carry, low power consumption and other excellent characteristics, esp...

AI Technical Summary

Problems solved by technology

However, converting signals such as MIPI signals / HDMI signals / LVDS signals / eDP signals into RGB signals / mini-LVDS signals requires a dedicated signal conversion chip for conversion, and they are not compatible with each other; Micro-OLED microdisplays also require an additional CPU. / MCU manages its initialization data (first read the initialization code from the internal storage module of the micro-display, and then transmit it to the internal driving circuit of the micro-display after parsing) and power-on and power-on timing

[0005] This kind of drive has the following defects: low applicability, long time period (different dedicated signal conversion chips should be selected according to different host signal sources), large area of ​​circuit driver board, and is not conducive to the development of miniaturization and thinning (special signal conversion chips and CPU / MCU together occupy a large driver board area)
