Problems solved by technology

When the number of pixels in the display device further increases, the number of transistors in the demultiplexer circuit increases accordingly, so that the size of the demultiplexer circuit increases, and the occupied frame area increases, which is not conducive to the design requirements of the narrow frame of the display device.

Abstract

The embodiment of the invention provides a display panel and a display device. A plurality of transistors of a multiplexer circuit of the display panel comprise at least one first transistor. The first transistor comprises two control electrodes; the two control electrodes are respectively and electrically connected with the same clock control signal line through different connecting lines; therefore, the length of the first transistor can be increased in the arrangement direction of the data signal lines, the width of the first transistor in the extension direction of the data signal lines isreduced, the occupied area of the multiplexer circuit is reduced, the size of a non-display area in the extension direction of the data signal lines is reduced, and a narrow frame of the display panel is facilitated.

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] There are multiple pixels in the active matrix display panel, wherein the pixels in the same row can share one scanning signal line, and the pixels in the same column can share one data signal line, and each pixel is provided with a driving transistor, and the scanning signal line can The scanning signal provided by the driving chip is sequentially input to each row of pixels, and the driving transistor of the corresponding pixel is controlled to be turned on. The data signal line can input the data voltage signal provided by the driving chip into the pixel, so that the pixel can display and emit light. [0003] With the development of display technology, the requirements for the display effect of the display panel are getting higher and higher. The number of pixels in the display panel is increasing, an...
