Abstract

The invention discloses a display panel and a display device, and the display panel comprises at least one sub-panel. The sub-panel comprises a first light-emitting diode located in the main display area and a second light-emitting diode located in the peripheral wiring area; the first light-emitting diode comprises a first edge light-emitting diode adjacent to the peripheral wiring area, and the at least one second light-emitting diode and the first edge light-emitting diode share the same pixel driving circuit; or the sub-panel further comprises a third light-emitting diode, the area of the third light-emitting diode is larger than that of the first light-emitting diode, and the projection of the third light-emitting diode is overlapped with the main display area and the peripheral wiring area, so that light emitting of the peripheral wiring area is achieved, the dark area of the peripheral wiring area is reduced, the narrow-frame display effect is achieved, and meanwhile the display effect is improved. When the display panel is used for large-area display, the splicing of the sub-panels can reduce the width of a splicing seam, and the display effect of the display panel is improved.

Description

A display panel and display device technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique Small-size LED display technology generally refers to a technology that uses LED chips with a size of less than 200 μm to form a display array. technique. Due to the small size LED chip has the advantages of self-illumination, small size, light weight, high brightness, long life, low power consumption and fast response time And other advantages, LED display technology has received more and more extensive attention. [0003] However, the existing small-size LED display panel has a relatively high The wide frame makes the screen ratio of the LED display panel low, which is not conducive to full-screen display, especially when the LED display panel is used for When splicing screens, a wider border will also lead to a larger width of seams in the splicing...
