A display panel is disclosed. The display panel includes a pixel driving circuit. The pixel driving circuit includes: a first transistor, wherein the first transistor and a light-emitting device are series-connected between a first power line and a second power line; and a second transistor, wherein the second transistor and the light-emitting device are series-connected between the first power line and the second power line. A width-to-length ratio of the first transistor is greater than a width-to-length ratio of the second transistor. A display device is further disclosed.

Display panel and display device

The present disclosure provides a display panel. The display panel includes: a substrate; a pixel driving circuit disposed on the substrate, the pixel driving circuit comprises driving sub-circuits; and a pixel layer disposed on the substrate, the pixel layer comprises pixel units arranged in an array, each of the pixel units comprises a red pixel, a green pixel, a first blue pixel, and a second blue pixel; each of the driving sub-circuits is in one-to-one correspondence with each color pixel, and a light transmission band of the first blue pixel is different from a light transmission band of the second blue pixel; in a first display mode, the pixel driving circuit drives the red pixels, the green pixels, and the first blue pixels to light up; in a second display mode, the pixel driving circuit drives the red pixels, the green pixels, and the second blue pixels to light up.

Display panel, control method of display panel, and display device

A display panel and a manufacturing method thereof, the display panel includes a first sub-pixel strip, a second sub-pixel strip, and a third sub-pixel strip arranged in a row direction or a column direction. The sub-pixels on each sub-pixel strip of the present disclosure have the same color and are arranged in series. The first sub-pixels on the first sub-pixel strip and the second sub-pixels on the second sub-pixel strip are staggered to improve flatness of printing the luminous material and luminous uniformity of OLED devices.

Display panel and manufacturing method thereof

The present invention provides a display panel. The display panel includes at least three sub-pixel regions. The sub-pixel regions are arranged along a direction of a scan line. A channel region of each driving TFT in the same sub-pixel region has a same width-to-length ratio. Along a direction from a signal input end to a signal output end of the scan line, the width-to-length ratio of the channel region of each driving TFT of any of the sub-pixel regions is smaller than that of a previous one of the sub-pixel regions.
