Problems solved by technology

The front-facing camera of a smartphone constrains the screen design, making it difficult to design the screen
In order to reduce the space occupied by the camera, screen designs including cutouts or punch holes have been adopted in smartphones, but the screen size is still limited due to the camera so that full screen display cannot be achieved

Abstract

The invention relates to a display panel and a display device using the same. A third pixel region having the same PPI as the first pixel region is disposed between the first pixel region and the second pixel region having different PPIs per inch. In the third pixel region, some of the pixels emit light as on pixels, and the remaining background pixels other than the on pixels are driven as off pixels or low-luminance pixels.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2020-0131112 filed on October 12, 2020, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a display panel having partially different resolutions or pixels per inch (PPI) and a display device using the display panel. Background technique [0004] Electroluminescent display devices are roughly classified into inorganic light emitting display devices and organic light emitting display devices according to the material of the light emitting layer. An active matrix type organic light emitting display device including a self-emitting organic light emitting diode (hereinafter referred to as "OLED") is advantageous in that a response time is fast and luminous efficiency, luminance, and viewing angle are large. In an organic light emitting display device, an OLED is for...
