Abstract
The utility model discloses a kind of cover board, touch screen and display modules.The cover board includes transparent substrate and the black ink and colourless semi-transparent ink that are arranged on the transparent substrate back side, and the black ink is located in non-visible area, and the colourless semi-transparent ink is located on visible area.The cover board reaches reduction reflection light by reducing light-inletting quantity of the ambient on visible area, improves breath screen between visible area and non-visible area integrally black effect, moreover it is possible to improve and be bonded effect with touch function layer or display screen, prevent from generating bubble when being bonded.
Description
Technical field
The utility model relates to display field more particularly to a kind of cover boards, touch screen and display module.
Background technique
Have in the visible area of display module and permitted multilayered structure, include cover board, touch function layer and display screen, and touches
Functional layer includes touch electrode and touches substrate again, include again in display screen upper polarisation, upper substrate, CF film, liquid crystal molecule,
TFT electrode, lower substrate and lower polarisation, will also be along with the OCA glue of stickup between each layer, when ambient is injected from upper one layer
At next layer, since optical index difference will generate light reflection between two layer structures, cause visible area when ceasing screen state
And non-fully black, but the color effects of " partially grey ", " partially thoroughly " are showed, but the black ink in non-visible area has been
All black, there is obvious line of demarcation between the Ink-- Black in the non-visible area of display module and visible area top panel black,
Affect the black effect of one of the display module when ceasing screen.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of cover board, touch screen and display module.It should
Cover board reaches reduction reflection light by reducing light-inletting quantity of the ambient on visible area, improves visible area and non-visible area
Between the integrated black effect of breath screen, moreover it is possible to improve and be bonded effect with touch function layer or display screen, prevent from generating gas when being bonded
Bubble.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of cover board, including transparent substrate and the black ink and colourless semi-transparent oil that are arranged on the transparent substrate back side
Ink, the black ink are located in non-visible area, and the colourless semi-transparent ink is located on visible area.
Further, the light transmittance of the colourless semi-transparent ink is between 30%-70%.
Further, the surface of the black ink and colourless semi-transparent ink flushes.
Further, the transparent substrate is plastic base, glass substrate or sapphire substrate.
A kind of touch screen, including above-mentioned cover board and touch function layer, the touch function layer is fitted in the cover board
On the back side.
Further, the touch-sensitive area of the touch function layer is located at visible area, and peripheral wiring area is located at non-visible area.
Further, the touch function layer is fitted on the cover board entirely by the first OCA glue.
A kind of display module, including above-mentioned cover board or above-mentioned touch screen and display screen, the display screen fitting
On the back side of the cover board or touch screen.
Further, the viewing area of the display screen is located on visible area, and rim area is located in non-visible area.
Further, the display screen is fitted on the back side of the cover board or touch screen entirely by the 2nd OCA glue.
The utility model has the following beneficial effects: cover board silk-screen on visible area has one layer of colourless semi-transparent ink, institute
Stating colourless semi-transparent ink can isolate a part of ambient, reduces light-inletting quantity of the ambient on visible area, exists in this way
Reflection light can also be reduced in the case that the touch function layer and display screen of rear end are constant to the reflectivity of ambient, so that
Visible area seems more black when ceasing screen state, improves breath screen between visible area and non-visible area integrally black effect.
Detailed description of the invention
Fig. 1 is the schematic diagram of cover board provided by the utility model；
Fig. 2 is the schematic diagram of touch screen provided by the utility model；
Fig. 3 is the schematic diagram of display module provided by the utility model；
Fig. 4 is the schematic diagram of another display module provided by the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in Figure 1, a kind of cover board, including transparent substrate 101 and the black oil being arranged on the transparent substrate back side
Ink 102 and colourless semi-transparent ink 103, the black ink 102 are located in non-visible area, and the colourless semi-transparent ink 103 is located at
On visible area.
Cover board silk-screen on visible area has one layer of colourless semi-transparent ink 103, and the colourless semi-transparent ink 103 can isolate
Fall a part of ambient, light-inletting quantity of the ambient on visible area is reduced, in this way in the touch function layer of rear end and display
Reflection light can also be reduced in the case that screen is constant to the mass reflex rate of ambient, so that visible area is when ceasing screen state
Seem more black, improves breath screen between visible area and non-visible area integrally black effect.
Preferably, the light transmittance of the colourless semi-transparent ink 103 is between 30%-70%.
In addition, due to the presence of the colourless semi-transparent ink 103, so that visible area and non-visible area on the cover board back side
Between difference in height it is smaller, can reduce subsequent fitting touch function layer 201 or fitting difficulty when display screen 301, improve
It is bonded effect with touch function layer 201 or display screen 301, prevents from generating bubble when fitting.
It is therefore preferred that the surface of the black ink 102 and colourless semi-transparent ink 103 flushes.
The transparent substrate 101 can be, but not limited to as plastic base, glass substrate or sapphire substrate.
Embodiment two
As shown in Fig. 2, a kind of touch screen, including cover board described in embodiment one and touch function layer 201, the touch
Functional layer 201 is fitted on the back side of the cover board.
The touch-sensitive area that touch sensor is used to form in the touch function layer 201 is located at visible area, for binding
The peripheral wiring area for touching FPC and touching driving IC is located at non-visible area.
The touch function layer 201 is preferably fitted on the cover board by the first OCA glue 202 entirely.
