Description
Technical Field
The invention relates to an electronic product, in particular to a method for manufacturing an LCD integrated black screen.
Background
With the continuous popularization and change of the intelligent display market, the life connection is tighter by the interconnection of everything. The application performance of intelligent wearable display in life is more and more extensive. Compared with an intelligent watch, the intelligent bracelet has the advantages of being light, convenient and low in power consumption, and meanwhile, due to the pertinence of functions, the comprehensive exercise health analysis system is favored by young groups. Depending on the requirement of fashion and convenience of the user group, the display of the bracelet in the existing market is still the LCD display. But be different from the integrative black effect of high-end intelligent wrist-watch OLED, this type bracelet shows still that integrative black effect is poor not enough. The invention mainly faces to wearing intelligent display products, and can effectively replace TP attaching OCA filling materials while realizing the integral black display effect of the intelligent bracelet LCD, thereby realizing the cost saving of process optimization.
The common touch screen is generally made of a PET film, and the PET film is made of an anisotropic material and has a birefringence effect, so that in actual use, a window area displays gray black, a frame displays black, a display area and the frame have different colors after screen refreshing, and the appearance aesthetic effect is poor. The effect of screen black integration is required to be achieved by reducing the transmittance of the cover plate (usually, the transmittance is required to be less than 55%, and the effect is achieved by screen printing or pasting a semi-permeable film material, semi-permeable ink or semi-permeable optical adhesive under the transparent cover plate), but the transmittance during display is also sacrificed, the display brightness is insufficient or the power consumption is too large (the backlight brightness is improved to improve the display brightness, so that the energy consumption is increased), and the consumption requirements of the existing application groups are difficult to match.
Disclosure of Invention
The invention aims to further reduce the power consumption of products, adopts isotropic materials to manufacture the touch screen functional film, and solves the technical problems of high power consumption and low brightness in the prior art by controlling related processes.
The manufacturing method of the low-power-consumption integrated black LCD screen designed for solving the technical problems comprises the steps that the display screen is a touch liquid crystal display screen, the touch liquid crystal display screen comprises a TP cover plate, a display module is attached to the lower portion of the TP cover plate through transparent pressure-sensitive adhesive, a cover film of a touch control screen in the TP cover plate is made of isotropic film materials, and a touch control circuit is sputtered on the cover film; the cover film comprises PMMA, TAC or COP.
The covering film replaces an upper covering film of a front polarizer in the display module and is directly attached to a base material of the polarizer; when the touch control circuit is sputtered, the sheet resistance of the conductive material on the covering film is controlled to be 300-400 ohms; when the touch control circuit is sputtered, the shadow is removed by adopting a shadow removing process; meanwhile, the cover plate in the TP cover plate can be made of a material with high light transmittance.
On the basis of the traditional integrated black display screen, the touch function sheet is made of isotropic materials, so that the integrated black display effect is realized, and the aims of improving the brightness and reducing the energy consumption are also realized in a targeted manner.
Drawings
Fig. 1 is a schematic structural view of an integrated black screen in a conventional mode. Fig. 2 is a schematic structural diagram of an integrated black screen according to the present invention. FIG. 3 is a schematic view of the combination of an integrated black screen cover film and a cover film on a surface polarizer according to the present invention.
Detailed Description
Specific embodiments of the present invention are described with reference to the above drawings.
As can be seen from FIG. 2, the manufacturing method of the low power consumption integrated black LCD screen of the present invention includes that the display screen is a touch liquid crystal display screen, which includes that a TP cover plate 10 is attached to a display module 50 through a transparent pressure sensitive adhesive 20, a cover film 11 of the touch control screen in the TP cover plate 10 is made of an isotropic film material, and a touch control circuit is sputtered on the cover film 11; the cover film 11 preferably comprises PMMA, TAC or COP material, although other isotropic materials are not excluded. The invention utilizes the characteristic of no refraction of isotropic material, thereby eliminating the influence of birefringence and improving the effect of integral black.
Meanwhile, as can be seen from fig. 2 and 3, the cover film 11 is directly attached to the base material of the polarizer instead of the upper cover film of the front polarizer 51 in the display module 50; when the touch control circuit is sputtered, the sheet resistance of the conductive material on the covering film 11 is controlled to be 300-400 ohms; when the sputtering is carried out on the touch control circuit, the shadow is removed by adopting a shadow removing process. On the basis of adopting the isotropic material, the thickness of the conductive material is further controlled, when the square resistance is controlled within the range of 300-400 ohms, the conductive material does not influence the vision and the light transmission, and the influence of the conductive material can be further eliminated by adopting a shadow eliminating process.
In view of the application of the above-mentioned various technologies, the cover plate in the TP cover plate 10 may be made of a material with high light transmittance, and has higher definition and better vision.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
