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

Abstract

The embodiment of the invention provides a display module and a manufacturing method thereof, and a display device, relates to the technical field of display, and can improve the signal attenuation caused by an IR Drop phenomenon on a signal line. The display module comprises a display panel, a display flexible circuit board, an auxiliary flexible circuit board and a driving circuit. The display panel is provided with a first signal line, the display flexible circuit board is connected with the first signal line through a first side edge of the display panel, and the auxiliary flexible circuitboard is connected with the first signal line through a second side edge of the display panel, wherein the first side edge and the second side edge are located at different sides of the display panel. The driving circuit is connected with the display flexible circuit board and the auxiliary flexible circuit board so as to provide a power supply voltage signal for the first signal line through thedisplay flexible circuit board and the auxiliary flexible circuit board.

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...
