Description
Technical field
The utility model is related to display technology field, more particularly to a kind of In-cell liquid crystal display devices.
Background technology
Liquid crystal display（Liquid Crystal Display, LCD）Shield as a kind of common flat type display,
It is widely used in the screen displays such as television set and computer.Since LCD screen surface refractive index and air refraction are significantly different,
To indoors or extraneous strong light sub-screen will appear reflex, cause display screen be difficult to present in the case where not showing it is pure
Black, the strong influence visual display effect of screen.
Utility model content
The purpose of this utility model is to provide a kind of In-cell liquid crystal display devices, whole by the way that moth eye film is arranged
The anti-reflection effect for improving display screen enhances display screen visual display effect.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of In-cell liquid crystal display devices, including：Touch-control display module, and in the touch-control display module
CF glass, which is characterized in that the touch-control display module includes TFT glass, liquid crystal layer from bottom to top and is integrated in described
Touch control layer on liquid crystal layer, the CF glass top surfaces are provided with moth eye film, and the In-cell liquid crystal display devices are in 550nm
Reflectivity is below 1.15% when wavelength light source irradiates.
Further, the moth eye film is the optical thin film that surface has nanoscale array of protrusions.
Further, the moth eye film includes base film and superficial film, and the skin covering of the surface includes for nanoscale protrusion
Array.
Further, the touch control layer is the nano indium tin metal oxide ITO sensors for sensing touch point.
The utility model additionally provides described in any one of a kind of portable electronic product, including above-mentioned technical proposal
In-cell liquid crystal display devices.
In-cell liquid crystal display devices provided by the utility model, including：Touch-control display module, and touched positioned at described
Control display module on CF glass, which is characterized in that the touch-control display module from bottom to top include TFT glass, liquid crystal layer with
And integrated touch control layer on the liquid crystal layer, the CF glass top surfaces are provided with moth eye film, the In-cell liquid crystal displays
Device when 550nm wavelength light sources irradiate reflectivity below 1.15%；So so that the interface of touch screen upper surface and air
Between refractive index along depth direction be in consecutive variations, hence it is evident that reduce the screen table caused by refractive index change dramatically
Face reflex eventually reduces the reflex of full screen.Technical solution provided by the utility model is relative to existing skill
Art can significantly improve the anti-reflection effect of liquid crystal display device, hence it is evident that improve the display effect of display screen.
Description of the drawings
Fig. 1 is the In-cell liquid crystal display device schematic diagrames of the utility model embodiment.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the In-cell liquid crystal display devices of the utility model embodiment include touch-control display module, and
CF in touch-control display module（Colored filter）Glass 4, wherein touch-control display module include TFT from bottom to top（Film
Transistor）Glass 1, liquid crystal layer 2 and the touch control layer 3 being integrated on liquid crystal layer 2,4 upper surface of CF glass are provided with moth eye film 5,
The In-cell liquid crystal display devices when 550nm wavelength light sources irradiate reflectivity below 1.15%.
In the utility model embodiment, moth eye film 5 is the optical thin film that surface has nano projection array, and moth eye film 5 is wrapped
Base film and superficial film are included, superficial film includes nanoscale array of protrusions.
The touch control layer of the utility model embodiment is the nano indium tin metal oxide ITO sensings for sensing touch point
Device.
When light is propagated between the different object of refractive index, interface that can be between object reflects.Due to sky
Gas refractive index is that 1.0, CF glass top surface refractive index is 1.5, and the two refractive index is significantly different, is shielded indoors or under extraneous strong light
Scene plot face still will appear apparent reflex, cause screen that ater can not be presented, to affect the vision of screen
Display effect.Moth eye film is to imitate the bionics product of the fine uneven structure in moth eyes, and principle is by described
Nano level fine protrusions are arranged in interface, to make refractive index that consecutive variations occur, therefore be not in refractive index obviously not
Same interface, and then achieve the purpose that prevent reflection.The utility model in CF glass top surfaces by being arranged moth eye film, to make
Air to CF glass top surfaces refractive index occur consecutive variations, i.e., the gradual change formed between air and inside of eye it is effective
Refractive index, to which the antireflection rate and contrast of liquid crystal display device be greatly improved.
Reflectivity is the function of refractive index, and is increased with the increase of refractive index.Air refraction is 1, when light from
When being incident on CF glass surfaces in air, 4% reflectivity occurs for appointment, and the In-cell liquid crystal display devices of the utility model pass through
Moth eye film is set in CF glass top surfaces, outermost layer reflectivity can be reduced to 0.3% or so, it is entire to greatly reduce
The reflectivity of product.It is compared by test data, reflectivity is 5.22% to common In-cell display screens at 550 nm, this practicality
Reflectivity is 1.15% to new embodiment In-cell display screens at 550 nm, the In-cell liquid crystals of the utility model embodiment
Showing device greatly reduces the reflectivity on surface, improves the display effect for improving display screen.
Moreover, the utility model embodiment additionally provides a kind of portable electronic product, including above-described embodiment institute
The In-cell liquid crystal display devices stated.
Finally, it should be noted that above example is only to illustrate the technical solution of the utility model embodiment rather than right
It is limited, although the utility model embodiment is described in detail with reference to preferred embodiment, this field it is common
Technical staff should understand that still be modified or replaced equivalently the technical solution of the utility model embodiment, and this
A little ranges changed or equivalent replacement cannot also make modified technical solution be detached from the utility model embodiment technical solution.
