Problems solved by technology
However, in the display panel, under each pixel there is a pixel circuit that controls the light emission of the pixel and an opaque pixel electrode, which makes the transmittance of the entire display panel relatively low, resulting in insufficient light received by the photosensitive device for fingerprint identification, and the signal Low noise ratio, fingerprint recognition is not sensitive

An embodiment of the present invention provides a display panel, the display panel includes a driving circuit, a light emitting device and a fingerprint identification unit, the light emitting device includes a first electrode, a second electrode and a An organic functional layer between electrodes, the fingerprint identification unit is arranged on the side of the drive unit away from the display unit; the drive circuit includes a light emission control transistor and a first initialization transistor, the light emission control transistor and the light emission control transistor The first initialization transistors are all connected to the first electrodes through first via holes; the drive circuit includes at least a first drive circuit, and the first via holes of the first drive circuit are connected to the first initialization transistors The minimum distance of the gate signal line is smaller than the minimum distance of the gate signal line connected to the first hole and the light emission control transistor. In this way, the light-transmitting area in fingerprint recognition is increased, and the accuracy of fingerprint recognition is increased.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method of the display panel. 【Background technique】 [0002] At present, full-screen displays are favored by more and more consumers, and there is no room for a fingerprint recognition module on the front of a display device. Therefore, the fingerprint recognition technology under the screen is applied to the display device. The fingerprint recognition under the screen does not occupy the front space but can realize the front fingerprint recognition. The principle of fingerprint recognition under the screen is that the display panel itself or the light source below the height of the display panel emits light, which shines on the finger and then reflects to the photosensitive device for fingerprint recognition. However, in the display panel, under each pixel there is a pixel circuit that controls the light emission ...
