Description
Technical Field
The invention relates to the field of display, in particular to a display panel and a manufacturing method of the display panel.
Background
At present, the in-plane hole opening technology in the industry is divided into a through hole and a blind hole, wherein the through hole means that a circular hole space is reserved in a glass substrate color film and an array substrate during film coating, and the circular hole is ground during cutting so as to realize the in-plane hole opening design of a liquid crystal display panel product. And when the color film substrate and the array substrate are laminated, liquid crystal is dripped into the round hole space, a round light-transmitting area is formed on the glass substrate, and the design of blind holes in the surface of a liquid crystal display panel product is realized.
Because of no support column (PS) process in the blind hole position of the blind hole product, when a color film substrate and an array substrate are combined into a plate, in the vacuum assembly process, glass on the blind hole can deform to a certain extent due to the influence of vacuum pressure, the glass substrate at the blind hole is sunken inwards, the light transmission path of the blind hole is influenced, and therefore the camera shooting function of the product is influenced.
Specifically, as shown in fig. 1, which is a schematic structural diagram of an existing liquid crystal display panel when completing vacuum assembly into a cell, a liquid crystal display panel 90 includes an array substrate 91 and a color filter substrate 92 that are oppositely disposed, a first slot 911 is disposed in the array substrate 91, a second slot 921 corresponding to the first slot 911 is disposed in the color filter substrate 92, and a blind hole 93 is formed by the first slot 911 and the second slot 921; in the production process, the light transmittance of the blind holes 93 can be ensured by using the form of hollowing out the light shielding layer in the blind holes 93 and filling the liquid crystal 941. However, since a part of the film layer is hollowed in the blind hole 93, there is no supporting pillar process in the blind hole 93, that is, there is no supporting pillar in the blind hole 93 to play a supporting role, so that after the liquid crystal 941 is dropped in vacuum, when the color film substrate 92 and the array substrate 91 complete vacuum assembly into a box and enter an atmospheric pressure environment, the color film substrate 92 and the array substrate 91 in the blind hole 93 will be recessed inwards under the influence of atmospheric pressure, and the curvature of the surfaces of the color film substrate 92 and the array substrate 91 changes, so that the color film substrate 92 and the array substrate 91 form a concave lens effect in the blind hole 93, and interference fringes appear in the blind hole 93.
Fig. 2 is a schematic structural view of the liquid crystal display panel shown in fig. 1 being depressed inward under the influence of atmospheric pressure. And liquid crystal display panel 90 and apron are carrying out the vacuum laminating back, have the vacuum cavity between apron and the liquid crystal display panel 90, because the effect of vacuum cavity negative pressure makes apron towards vacuum cavity lateral buckling, can aggravate concave lens phenomenon, finally cause the unable normal focus of camera under the hole, influence the camera effect of shooing.
