Abstract

Provided are an OLED display module and a manufacturing method thereof. The OLED display module comprises an OLED display screen (20) and a driver chip (21). The OLED display screen (20) is provided with a display signal input end (22). The driver chip (21) is fixed to a back surface of the OLED display screen (20) and is provided with a driving signal output end (211). Signals outputted by the driving signal output end (211) are led from at least two ends of the driver chip (21) and eventually inputted to the display signal input end (22). The OLED display module having the above structure can reduce design risk and increase yield.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display module, a display device and a preparation method of the display module. Background technique [0002] With the development of technology, electronic devices are becoming more and more common. For electronic equipment to display normally, in addition to a display screen, a driver chip and a flexible circuit board are also provided. [0003] Figure 1A It is a structural schematic diagram of the front of the display module in the prior art, Figure 1B It is a structural schematic diagram of the back of the display module. The front of the display screen 10 will leave a large part of the lower border (border) area 12 below the effective display area 11, which is used to place the driver chip 13 and the flexible circuit board 14, so as to provide the drive signal to the source input terminal 15 and drive the chip. 13. Through its own input pad (Input pad), output...
