Problems solved by technology

[0003] Existing OLED display panels include a display area and upper, lower, left, and right frame areas, and the lower frame area generally includes a wiring area and a terminal bending area (pad bending area), and the wiring area is provided with fan-shaped wiring. (fanout routing), VDD routing and VSS routing occupy a large frame width, and the bending radius of the pad bending area has a bending limit, which cannot be further reduced, which leads to a larger width of the lower frame area, making OLED It is difficult for display panels to achieve narrow borders, and this problem needs to be solved urgently

Abstract

The invention provides a display module which comprises a display panel, the display panel is provided with a display area, a bending area and a wiring area located between the display area and the bending area, the display panel comprises a first substrate, a conductive layer, a second substrate and a driving circuit layer which are sequentially arranged in a stacked mode, the first substrate is provided with a notch in the bending area, and the first substrate is provided with a first electrode. The second substrate is provided with a via hole in the wiring area, the driving circuit layer comprises a signal line extending from the display area to the wiring area, the conductive layer comprises a connecting line extending from the bending area to the wiring area, one end of the connecting line is exposed by the notch, and the other end of the connecting line is electrically connected with the signal line through the via hole. According to the display panel, the connecting line electrically connected with the signal line is arranged between the two substrates, and the notch for exposing the connecting line is formed in the first substrate in the bending area, so that an external circuit can transmit an electric signal to the display area through the connecting line, the width of a lower frame of the display panel is reduced while the display effect is guaranteed, and the screen-to-body ratio is increased.
