Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises a multi-path selection circuit, a data signal source terminal and a gating signal output terminal, and the multipath selection circuit comprises a plurality of switch circuit groups. Each switching circuit comprises a gating signal receiving terminal and a data signal output terminal; the gating signal outputterminals comprise a first type gating signal output terminal and / or a second type gating signal output terminal; the first type gating signal output terminal and the second type gating signal outputterminal are positioned on different sides of the data signal source terminal; sub-pixels emitting light of the same color are electrically connected with a plurality of data signal output terminalsin the same switching circuit group through data lines, and gating signal receiving terminals of at least one switching circuit group are electrically connected with the first type gating signal output terminal or electrically connected with the second type gating signal output terminal. According to the display panel and the display device provided by the invention, the number of channels is reduced, and meanwhile, the problem of vertical stripes is solved.

Description

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 [0002] With the development and progress of display technology, people have put forward higher requirements on the appearance design of display devices, and narrow bezels have become the goal pursued by people. Due to the limitation of the frame space, a demultiplexer (DEMUX) is usually used to decompose a signal channel into multiple signal channels, and time-division multiplex the output signal channels of the driver chip, thereby reducing the number of output pins of the driver chip. [0003] However, the DEMUX circuit decomposes one signal channel into more signal channels. Therefore, more clock control signals CKH are required. Since the clock control signals CKH of the existing DEMUX circuit are driven by both sides, more clock control signals CKH are required. Therefore, a wider chip-...

Problems solved by technology

[0003] However, the DEMUX circuit decomposes one signal channel into more signal channels. Therefore, more clock control signals CKH are required. Since the clock control signals CKH of the existing DEMUX circuit are driven by both sides, more clock control signals CKH are required. Therefore, a wider chip-on-film (COF) is needed to bind the signal line of CKH to the driver chip, so that the chip-on-chip film takes up a large space, which is not conducive to reducing the width of the frame
