Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0030] figure 1 It is a schematic diagram of the structure of an existing display panel. like figure 1 As shown, the display panel includes a display area 101 , a transition area 102 and a light transmission area 103 , the transition area 102 at least partially surrounds the light transmission area 103 , and the display area 101 at least partially surrounds the transition area 102 . The transmittance of the light-transmitting area 103 is relatively high, and may be a camera area. When the display panel is full-screen display, t...

Abstract

The invention discloses a display panel and a display device. The display panel includes a first display area, a second display area and a non-display area, the light transmittance of the first display area is greater than that of the second display area; the first display area is provided with a first display unit, and the non-display area is provided with a first display unit. A first gate drive circuit and a first pixel circuit are provided, the first pixel circuit is connected with the first display unit, and is used to provide driving current for the first display unit; the first gate drive circuit is connected with the first pixel circuit, and is used for for providing driving signals for the first pixel circuit. The first pixel circuit is arranged in the non-display area, which can avoid additionally setting the transition area between the first display area and the second display area to place the first pixel circuit, thereby improving the overall display effect of the display panel. In addition, the first gate driving circuit can independently control the first pixel circuit to drive the first display unit to emit light, which can reduce the demand of the display panel for the driving capability and is beneficial to reduce the cost of the display panel.

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] The current display panel is developing in the direction of full screen. In a full screen, a light-transmitting area with a relatively large light transmittance needs to be set in the display area for placing structures such as cameras. At this time, the pixel circuit of the light-transmitting area can be arranged in the peripheral area of ​​the light-transmitting area, so as to ensure the light transmittance of the light-transmitting area. When the pixel circuits are arranged in the peripheral area of ​​the light-transmitting area, the pixel density (Pixels Per Inch, PPI) of the light-transmitting area can be reduced to reduce the number of pixel circuits arranged in the peripheral area, thereby reducing the occupied area of ​​the peripheral area. At this time, the PPI of the light-...
