Background
This section provides merely background information related to the application, which is not necessarily prior art.
At present, the LCD panel of the mobile phone still occupies a low-end main market in the mobile phone market due to low cost, and the front camera is the standard of the mobile phone at present. Existing front cameras generally have 3 corresponding punching modes: ① . The through hole screen and the LCD through hole scheme are to punch through the LCD panel, the polarizing plate and the backlight together, so that the process from glass to a module is more complicated. ② . The blind hole screen with liquid crystal has the advantages that physical holes are not required to be drilled on the screen completely, only holes are required to be drilled on the backlight layer and the polaroid layer on the TFT LCD display screen, the array glass and the color film glass substrate do not need to be drilled, mask blocking is performed at the hole positions, no graph is manufactured, and the liquid crystal with the hole parts is left in the panel. ③ . The blind hole screen without liquid crystal is almost similar to the blind hole screen with liquid crystal, and the biggest difference between the blind hole screen without liquid crystal and the blind hole screen with liquid crystal is that whether liquid crystal exists in the panel layer or not, the blind hole screen without liquid crystal removes the liquid crystal in the hole area, but an additional packaging process is needed to separate the liquid crystal. Compared with the through hole screen, the blind hole screen without liquid crystal and the blind hole screen with liquid crystal do not need to drill holes on the array glass and the color film glass substrate, so that the process complexity of the glass to the module is greatly reduced, and compared with the blind hole screen without liquid crystal and the blind hole screen with liquid crystal, the blind hole screen with liquid crystal has advantages in beauty and cost, and becomes the mainstream of punching design of the liquid crystal panel.
However, the blind hole screen in the related art is prone to yellowing when pressed around the blind hole position.

In addition, while achieving the difference in the heights of at least part of the spacers 141 in the transition region 110, a new layer (the layer structure of the blind via region 120 is the same as that of the display region 100) is not introduced, so that the manufacturing process is simplified.

Therefore, the strip-shaped spacer 1412 can be lifted, the height difference between the columnar spacer 1411 and the strip-shaped spacer 1412 is increased, and the columnar spacer 1411 can start to provide support only when the strip-shaped spacer 1412 is deformed by enough external force around the blind hole and is insufficient to provide support, so that the compression resistance around the blind hole can be improved, the uniformity of arrangement of the box thickness and the liquid crystal layer can be effectively ensured, the occurrence of yellowing phenomenon is avoided, and the display quality of the display panel 100 is improved.
