Problems solved by technology

Due to the increase in the size of the display device and the increase in resolution, the number of leads on the display substrate increases, and the length of the driving circuit board increases accordingly, resulting in an increase in the bending resistance, thereby reducing the curvature of the bending part of the driving circuit board and reducing the bending. The radius increases, which is not conducive to the realization of narrow borders

Abstract

The invention provides a driving circuit board. The driving circuit board is applied to a displaying device. The displaying device board comprises a displaying substrate, the displaying substrate comprises a displaying area and a lead area located around the displaying area, and the lead area is provided with a lead which extends from the displaying area; one end of the driving circuit board is used for being electrically connected with the lead of the lead area, the driving circuit board can be bent, and the other end of the driving circuit board is located at the side, deviating from the light emergence direction, of the displaying substrate; the driving circuit board is provided with through holes running through the driving circuit board, and the through holes are located on the bending portion of the driving circuit board. Correspondingly, the invention further provides the displaying device. The driving circuit board is easier to bend, and therefore a narrow frame of the displaying device is easily achieved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit board and a display device. Background technique [0002] Organic light-emitting devices (Organic Light-Emitting Device, OLED) have the advantages of active light emission, good temperature characteristics, low power consumption, fast response, wide viewing angle, ultra-thin and low cost, and have been widely used in display devices. In organic electroluminescent display devices, such as figure 1 As shown, the driving chip 11 is disposed on the driving circuit board 10 , and is electrically connected to the lead wires on the display substrate 20 through the signal lines on the driving circuit board, so as to provide driving signals for the display substrate 20 . After one end of the driving circuit board 10 is connected to the display substrate 20 , it is bent toward the side of the display substrate 20 away from the light emitting direction, so that the other...
