Embodiment 1

[0029] Such as figure 2 As shown, this embodiment provides an OLED display screen 200 with a touch function, including an OLED cover plate 201, an OLED substrate 202, and a touch screen 203 arranged in sequence, and a 3D film is arranged between the OLED cover plate 201 and the OLED substrate 202 204 , the side of the OLED cover plate 201 facing the OLED substrate 202 has a pit 201 ′, and the 3D film 204 covers the side of the OLED cover plate 201 facing the OLED substrate 202 .

[0030] The OLED substrate 202 is used to emit light and display images, and may include a base and a pixel unit array disposed on the base. The substrate includes a display area (pixel area) and a non-display area (frame area), and the display area is formed with scan lines, data lines intersecting with the scan lines, and a pixel unit array defined by the scan lines and data lines . Various wires are formed in the non-display area, such as power wires and clock wires, and gate drive circuits and ...

Embodiment 2

[0041] Such as image 3 As shown, this embodiment provides an OLED display screen with a touch function, including an OLED cover plate 201, an OLED substrate 202, and a touch screen 203 arranged in sequence, and a 3D film 204 is arranged between the OLED cover plate 201 and the OLED substrate 202 , the side of the OLED cover plate 201 facing the OLED substrate 202 has a pit 201 ′. The difference between this embodiment and the first embodiment is that the 3D film 204 is located in the pit 201'. Specifically, the 3D film 204 may be disposed at the bottom of the pit 201', and the 3D film 204 covers the entire area of ​​the bottom of the pit 201'. Because the area of ​​the bottom of the pit 201' is generally larger than the area of ​​the display area, the 3D film 204 covers the entire area of ​​the bottom of the pit 201', which can ensure that the 3D film 204 corresponds to the display area. Because the depth of the pit 201' is usually greater than the thickness of the 3D film ...

Embodiment 3

[0043] Such as Figure 4 As shown, this embodiment provides an OLED display screen with a touch function, including an OLED cover plate 201, an OLED substrate 202, and a touch screen 203 arranged in sequence, and a 3D film 204 is arranged between the OLED cover plate 201 and the OLED substrate 202 , the side of the OLED cover plate 201 facing the OLED substrate 202 has a pit 201 ′. The difference between this embodiment and other embodiments is that a part of the 3D film 204 is located in the recess 201', and a part covers the side of the OLED cover plate 201 facing the OLED substrate 202. Specifically, in Figure 4 Among them, the 3D film 204 covers the entire area of ​​the side of the OLED cover plate 201 facing the OLED substrate 202, that is, the 3D film 204 not only covers the bottom and side walls of the pit 201′, but also covers the area of ​​the side of the OLED cover plate 201 facing the OLED substrate 202. other areas.

Abstract

The invention provides an OLED (organic light emitting diode) display screen with a touch function and a preparation method of the display screen. The OLED display screen comprises an OLED cover board, an OLED substrate and a touch panel which are sequentially arranged, a 3D (three-dimensional) film is arranged between the OLED cover board and the OLED substrate, a pit is formed in one surface of the OLED cover board and faces the OLED substrate, the OLED substrate is provided with a display area and a non-display area, and the 3D film and the pit at least correspond to a display area of the OLED substrate. According to the OLED display screen, the pit of the OLED cover board replaces a traditional air gap, the 3D film is directly arranged on the surface of the OLED cover board or partly or completely arranged in the pit of the OLED cover board, so that an overall structure can be thinner and more simple, a process can be simplified, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display screen with a touch function and a manufacturing method thereof. Background technique [0002] Among the input devices that cooperate with the display device, the touch screen is currently the most simple, convenient and natural input device, which has the advantages of durability, fast response, space saving, easy communication, etc., and is widely used in the displays of various portable devices. . [0003] Existing touch-screen display devices usually use a close mechanical fit between the touch-screen finished product and display products such as cathode ray tube (CRT), liquid crystal display (LCD), plasma display (PDP), organic electroluminescent display (OLED), etc. Assembled together for touch functionality. For LCD with touch function, such as figure 1 As shown, after the touch screen body 102 is bonded to the touch screen cover 101 , it is bonded to t...
