Abstract

The invention provides a display panel and a display device. The display panel includes a plurality of sub-display panels that are spliced ​​together; the sub-display panel includes a base substrate, a thin-film transistor array layer, and a light-emitting layer that are stacked in sequence; the thin-film transistor array layer includes a constant voltage signal line for transmitting a constant voltage; the sub-display panel The constant-voltage signal line of the sub-display panel is electrically connected to the constant-voltage signal line of the sub-display panel adjacent to the sub-display panel through the connection structure; the connection structure is located on the side of the base substrate away from the light-emitting surface of the sub-display panel. The display device includes a display panel. In the present invention, the constant voltages of the constant-voltage signal lines in the two adjacent sub-display panels are consistent, so that the luminance of the light-emitting layers in the two adjacent sub-display panels is consistent, so that the display uniformity of the display panels is excellent . At the same time, the connection structure will not block the light-emitting surface of the display panel, so as to ensure the display effect of the display panel.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In theaters, conference rooms, open air and other occasions, super-large-screen displays are often used. Due to the large display area of ​​super-large-screen displays, it is generally used in the form of splicing multiple smaller display The displayed image is divided into multiple parts, which are respectively sent to the displays with smaller display areas for display. [0003] figure 1 It is a structural schematic diagram of a display panel in the prior art. [0004] Such as figure 1 As shown, in the prior art, the display panel 10 includes a plurality of sub-display panels 100 , and the sub-display panels 100 include constant voltage signal lines 110 . The constant voltage signal lines 110 of each sub-display panel 100 are independent. This results in an uneven signal of the constant voltag...
