Problems solved by technology

[0002] In the existing display device, the power supply voltage is generally provided to the power supply voltage line (also called VDD line) through the chip, but because the VDD line itself has a certain resistance, the farther away from the chip (for example, in the display panel, On the side opposite to the chip), the power supply voltage signal is significantly attenuated due to the IR Drop phenomenon, which leads to a decrease in the LRU (Long Range Uniformity) of the display device and a decrease in the quality of the display screen

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a manufacturing method thereof, and a display device. Background technique [0002] In the existing display device, the power supply voltage is generally provided to the power supply voltage line (also called VDD line) through the chip, but because the VDD line itself has a certain resistance, the farther away from the chip (for example, in the display panel, On the side opposite to the chip), the power supply voltage signal is significantly attenuated due to the IR Drop phenomenon, which leads to a decrease in the LRU (Long Range Uniformity) of the display device and a decrease in the quality of the display screen. Contents of the invention [0003] Embodiments of the present invention provide a display module, a manufacturing method thereof, and a display device, which can improve the problem of signal attenuation caused by the IR drop phenomenon on the sig...
