Panel structure for reducing peripheral brightness of display area

Technical Field

The utility model belongs to the technical field of show, concretely relates to reduce panel framework of peripheral luminance in display area.

Background

With the development of the times and the progress of science and technology, users have more sophisticated requirements on the appearance of mobile phone products, which leads to the continuous development of mobile phone products towards light, thin, power-saving and full-screen directions. The full screen display not only promotes the color value of the product, makes the product look more scientific and technological sense, and the higher screen accounts for the ratio and makes the system can show more information, promotes user's visual experience, so the full screen technique has become a popular trend of present display devices.

In order to increase the screen occupation ratio of the screen, reducing the frame of the screen has become an inevitable trend of current technology development. Mobile phone manufacturers gradually develop various special-shaped full-screen screens without reducing the necessary functions of a front camera, an infrared sensor, a loudspeaker receiver and the like, and the common special-shaped full-screen screens in the market comprise a sea-flowing screen, a water drop screen, a blind hole screen and the like. The screen occupation ratio of the blind hole screen reaches the highest specification, only a single photographic lens is left and arranged in the middle of the display screen after inductors required by all panels are integrated, the screen occupation ratio of more than 90 percent can be achieved, and the use experience of a user is greatly improved.

The conventional special-shaped screen is provided with a circle of BM frames around the display area because the non-display part of the special-shaped screen is positioned outside the AA display area, the BM frames are used for shielding metal wires on the side of a TFT (thin film transistor) which bypasses the position of a border, and the problem of partial brightness of the display area is caused because the liquid crystal Cell thicknesses (Cell Gap) at the periphery of the display area, the BM frames and the normal display area are different under the panel structure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a reduce panel framework of the peripheral luminance of display area to the peripheral problem of showing partially brightly of display area who proposes in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a reduce panel framework of peripheral luminance of display area, includes CF and display area, the edge of display area is provided with BM frame district and border district, be provided with the CF bed course on the CF, the CF bed course of BM frame district department is a district CF bed course, b district CF bed course and c district CF bed course in proper order, and the split becomes three kinds of different CF bed course heights, makes the descending that CF bed course height can two segmentations, in order to reach the purpose of buffering, a district CF bed course is BM, RGB, OC, PS from bottom to top in proper order, b district CF bed course is BM, OC, PS from bottom to top in proper order, c district CF bed course is BM, OC from bottom to top in proper order, reduces the perk of BM frame district position that leads to because of warping up the board effect, avoids the peripheral liquid crystal cell thickness of display area to be high, reduces the problem that the display area periphery is inclined to be bright.

Preferably, the PS includes MPS and SPS, and the PS is provided with a TFT.

Preferably, the height of the CF pad layer in the area a, the height of the CF pad layer in the area b, and the height of the CF pad layer in the area c are gradually decreased, so as to avoid the problem that the liquid crystal cell around the display area is too thick and the periphery of the display area is too bright.

Preferably, the CF cushion layer at the position of the border area is sequentially BM, OC and frame glue from bottom to top, so that a stabilizing effect is achieved.

Preferably, the height of the CF pad layer in the a-region is consistent with that of the CF pad layer in the display region, so that a transition function is conveniently realized.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a panel structure, which can effectively avoid the problem that the periphery of a display area is brighter by adjusting the height of a CF cushion layer at a BM frame and adopting a gradual height reduction mode of the cushion layer; the panel framework is actually measured to effectively reduce the difference between the thickness of the liquid crystal box at the periphery of the display area and the thickness of the liquid crystal box in the normal display area to be within 0.05 mm.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a panel structure for reducing peripheral brightness of a display area comprises a CF and the display area 1, wherein a BM frame area 2 and a border area 3 are arranged at the edge of the display area 1, a CF cushion layer is arranged on the CF, the CF cushion layer at the BM frame area 2 is sequentially a CF cushion layer at an a area, a CF cushion layer at a b area and a CF cushion layer at a c area, and the CF cushion layers are split into three different CF cushion layer heights, so that the CF cushion layer can descend in a two-section mode to achieve the purpose of buffering, the CF cushion layer at the a area is sequentially BM, RGB, OC and PS from bottom to top, the CF cushion layer at the b area is sequentially BM, OC and PS from bottom to top, and the CF cushion layer at the c area is sequentially BM and OC from bottom to top, thereby reducing tilting of the position of the BM frame area caused by a tilting plate effect, avoiding the phenomenon that a liquid crystal box at the periphery of the display area 1 is thicker and avoiding the problem that the periphery of the display area 1 is brighter.
