Description

technical field

[0001] Embodiments of the present invention relate to display technologies, and in particular to a display panel and a manufacturing method thereof. Background technique

[0002] At present, the full screen almost occupies a large proportion of the consumer product market, and the full screen on the market is essentially a display with a very high screen ratio. Therefore, how to further increase the screen ratio of the full screen has become the current display. A popular development direction of the screen. Based on this, the full screen punching technology (including actual digging and transparent blind hole technology) came into being. The full screen with punching design can not only meet the high screen ratio, but also cooperate well with accessories such as cameras. .

[0003] The display screen adopts a perforated design, and functional devices such as a camera can be placed at the perforated position. Using this full-screen technology can achieve a ...
