At present, the comprehensive screen requirement of the mobile phone is fully developed, and the comprehensive screen becomes the future trend. The screen of the full screen may be divided into a VA Area (Visual Area), an AA Area (Active Area), and a BM Area (Black Matrix). The VA area is all visible parts of the screen panel, the AA area is a part where display can be programmed and controlled, and the VA area is larger than the AA area. And the BM area is located at the outermost periphery of the VA, i.e., a screen black edge portion. Due to the structure of the screen, the width of the BM area, namely the width of the black edge, is also wider, and the current narrowest BM area of the OLED display screen is about 1.6mm, which is an obstacle to realizing the full screen technology. This application punches through the OCA glue film at the black border region of screen, makes the regional OCA glue film of black border have the effect of leaded light membrane or astigmatism piece, makes it light source conduction such as built-in OLED lamp on with light or center edge on the screen light and lights BM region.

When the screen is lightened, the BM area of the screen is lightened, the width of a black edge is visually reduced or the black edge is eliminated, and the maximum overall screen visual effect is realized.
As shown in fig. 2 to 4, in an embodiment, the screen 100 has a square structure, and includes a cover plate 110, a touch display device 120, an OCA adhesive layer 130, and an ink layer 140. The cover plate 110 and the touch display element 120 are stacked, and the area of the cover plate 110 is larger than that of the touch display element 120, so that the peripheral edge of the cover plate 110 protrudes out of the peripheral edge of the touch display element 120. The touch display element 120 includes a touch layer and a display layer, so that the screen 100 has a touch function and a display function. The ink layer 140 is located on the lower surface of the cover plate 110, the ink layer 140 extends inward from the edge of the cover plate 110 to form a ring structure, and at least a part of the ink layer 140 is located in the projection of the touch display element 120 on the cover plate 110. It can be understood that the ink layer 140 is a square ring-shaped structure and is located at the edge of the lower surface of the cover plate 110, and the inner ring of the ink layer 140 is located between the cover plate 110 and the touch display element 120, so that a part of the structure of the ink layer 140 overlaps with the edge of the touch display element 120. The lower surface of the cover plate 110 may be understood as a surface of the cover plate 110 facing a side of the touch display element 120. The portion of the touch display device 120 enclosed by the ink layer 140 is an effective area of the screen 100, as shown in fig. 3, the structure enclosed by the ink layer 140 is an AA area of the screen 100.
As shown in fig. 4, in an embodiment, the OCA glue layer 130 is adhered between the cover plate 110 and the touch display element 120. The area of the OCA adhesive layer 130 is smaller than or equal to the area of the cover plate 110, the area of the OCA adhesive layer 130 is larger than the area of the touch display element 120, and the edge of the OCA adhesive layer 130 protrudes out of the edge of the ink layer 140. The tip and the printing ink layer 140 coincide of OCA glue film 130, the thickness of OCA glue film 130 is greater than the thickness of printing ink layer 140.
As shown in fig. 4, in an embodiment, a hole 131 is formed in an end portion of the OCA adhesive layer 130 attached to the ink layer 140, and the ink layer 140 can transmit light, so that the BM area can be lighted when the screen 100 operates. The end of the OCA adhesive layer 130 attached to the ink layer 140 is provided with a hole 131, and light rays in the screen 100 can penetrate through the hole 131, so that the end of the OCA adhesive layer has the effect of a light guide film or a light diffuser. The ink layer 140 is made of black transparent ink, so that the ink layer 140 has a certain light transmittance, and a part of light transmitted by the light guide element 150 can pass through, which shows that the BM area is lighted.
The transparent ink is mainly characterized in that the ink has low covering power and good transparency, and is mainly prepared from a colorant or most of the ink prepared from fuel. The transparency of the clear ink is determined by the dye (pigment) and vehicle (containing auxiliaries), with the former playing a major role and the latter having little effect. The magnitude of transparency can be expressed in transmission coefficient. Assuming that the intensity of light entering the ink is I0 and the intensity of light passing through the ink is I, when the thickness of the ink is one centimeter, the ratio Q of I/I0 is called the transmission coefficient of the mineral. It can be seen that the stronger the absorption, the more opaque, i.e. the smaller the transmission coefficient. The light transmittance of the ink layer 140 is determined by the transparency of the transparent ink used in the present application, and the transparency of the transparent ink used in the present application is greater than 50%, so that the light transmittance of the ink layer 140 is greater than 50%, and light rays in the screen 100 can pass through the ink layer 140 to illuminate the ink layer 140.
As shown in fig. 4 and 5, in an embodiment, the light source 161 is disposed on the middle frame 160, and light is transmitted to the ink layer 140 through the hole 131 and penetrates the ink layer 140 to illuminate the BM area of the screen 100.
