Abstract

The embodiment of the invention provides a spliced display screen and a display device. The spliced display screen comprises a display screen group which comprises a plurality of sub-screens and a plurality of scanning driving circuits used for driving the sub-screens respectively, wherein each sub-screen comprises a display area, the display areas of the sub-screens face the same direction, a plurality of sub-pixels arranged in rows and columns are arranged in each display area, the sub-screens are arranged in an array mode, and the scanning driving circuits of the sub-screens arranged in thecolumn direction are connected in series; a substrate, wherein each sub-screen is connected to the substrate through a flexible circuit board, a control chip is arranged on the substrate, and the same scanning output end of the control chip is connected to any one of the plurality of scanning driving circuits which are connected in series. In the embodiment of the invention, the same scanning output end on the control chip can be connected with the scanning driving circuits of the plurality of sub-screens, so that the number of ports on the control chip is reduced, and the cost of splicing the display screen can be further reduced.

Description

technical field [0001] The present invention relates to the technical field of display equipment, in particular to a splicing display screen and a display device. Background technique [0002] A micro light emitting diode (Micro LED) is a device with a size ranging from several microns to several hundreds of microns. Since its size is much smaller than that of ordinary LEDs, it is possible to use a single LED as a pixel for display. A Micro LED display is a display that uses a high-density Micro LED array as a display pixel array to achieve image display. [0003] Existing Micro LEDs still have technical barriers in mass transfer technology and cannot meet the needs of commercialization. [0004] Therefore, there is an urgent need for a new spliced ​​display screen and a display device. SUMMARY OF THE INVENTION [0005] Embodiments of the present invention provide a splicing display screen and a display device, which aim to reduce the cost of splicing a display screen. ...
