Description
Technical Field
The invention relates to a touch screen structure, in particular to a touch screen structure which changes the position of a polarizer, adds a light blocking substance on the end face of a module and overcomes the defects of easy light leakage and easy edge visibility of narrow frame design.
Background
The touch panel has the characteristics of man-machine interaction and design diversity, and is widely applied to the external input interface of the instrument. In recent years, as consumer electronics have been widely used, there are more and more products that combine a touch function with a display, such as a mobile phone (mobile phone), a satellite navigation system (GPS navigator system), a tablet PC (tablet PC), and a notebook PC (laptop PC).
With the development of technology, people have higher and higher quality requirements for electronic products, and under strong competition, electronic manufacturers have increasingly aimed at making electronic products beautiful, light, thin and narrow, and hope that the larger the liquid crystal screen is, the better the screen is. Therefore, the existing mobile phones are developed to be ultra-light and ultra-thin, and the mobile phone screens are also made larger and larger within a limited range, generally, the frame regions around the liquid crystal screens do not have a display effect, and the appearance of the frame regions also affects the visual aesthetic effect, so electronic manufacturers are all dedicated to research and develop frame shrinking technologies.
Therefore, many manufacturers try to narrow the borders on both sides of the mobile phone within the range of the size of the mobile phone, so as to meet the current requirements of users. Referring to fig. 1, a typical touch screen structure 2 includes a cover glass 21, a touch electrode film 23, an adhesive layer 26, a polarizer 22, and a liquid crystal screen module 24. The narrow frame of the mobile phone also reduces the width of the glass black edge ink layer 212 of the liquid crystal display module, so that light cannot be completely blocked, when the backlight module is not lit, the light is easily incident to the backlight module 241 and the color filter panel 242 from the side surface of the touch module structure, and a white line is found to be generated at the edge of the screen when the screen is viewed frontally. When the backlight module 241 is turned on, and the display screen is observed at some angle (for example, 60 °), the edge of the display area may generate a very obvious bright line, which results in a poor visual effect and may not meet the quality requirement of the narrow frame of the mobile phone. Therefore, it is an urgent technical problem in the art to provide a touch screen structure that is used on a narrow bezel of a mobile phone and does not leak light.

Detailed Description
To achieve the above objects and advantages, the technical means and structure adopted by the present invention are described in detail with reference to the following drawings for fully understanding the preferred embodiments of the present invention, but it should be noted that the contents do not limit the present invention.
Fig. 2 is a schematic structural diagram of a touch screen structure according to a preferred embodiment of the invention. The invention provides a touch screen structure 1, which is used for overcoming the defects that white lines are generated at the edge of a conventional narrow-frame screen of a mobile phone under the condition that a backlight module is not lightened and bright lines are generated at the edge of the conventional narrow-frame screen of the mobile phone under the condition that the backlight module is lightened. The touch screen structure 1 includes a cover glass 11, a polarizer 12, a touch electrode film 13 and a liquid crystal screen module 14.
The cover glass 11 has the characteristics of dust prevention, scratch prevention and the like, and is used for protecting the touch electrode film 13 and the liquid crystal screen module 14 from directly contacting with the outside, and the mechanical property of the whole device can be improved at the same time, so that the device is not easy to damage. The cover glass 11 has a visible area 111 and an ink layer 112, the ink layer 112 is coated around an outer edge of a side of the cover glass 11, the visible area 111 can allow light to pass through, and the ink layer 112 can block light from passing through.
The polarizer 12 is attached to the cover glass 11, and the size of the polarizer 12 is slightly larger than the visible region 111, so that the visible region 111 can be covered when the polarizer 12 is attached to the cover glass 11.
The touch electrode film 13 is attached to the polarizer 12 to perform a main touch sensing function, and may be a transparent electrode film commonly used in a general touch module, and at least includes a first axial electrode layer, a first insulating layer, a second axial electrode layer, and a second insulating layer.
The lcd module 14 includes a backlight module 141 and a color filter panel 142, the color filter panel 142 is connected to the touch electrode film 13 through an adhesive layer 16, and the lcd module 14 has a light-reflecting outer edge 143.
The end surfaces of the polarizer 12, the touch electrode film 13 and the color filter panel 142 have a light blocking portion 15, and the light blocking portion 15 may be black ink or a light absorbing material. The light blocking portion 15 also covers the light reflection outer edge 143, and can block light from entering from the end surfaces of the polarizer 12, the touch electrode film 13, and the lcd module 14, and block light from being reflected from the light reflection outer edge 143, and the light blocking portion 15 blocks light from passing through the light reflection outer edge 143.
Referring to fig. 3 and 4, in a general touch screen structure, a polarizer is usually disposed between a liquid crystal display and a touch electrode, and the polarizer 12 is disposed between the cover glass 11 and the touch electrode, and the light blocking portion 15 is matched, so that when the liquid crystal screen module 14 is not lit, when external light passes through the polarizer 12 from the cover glass 11, the light intensity is half blocked, and the light blocking portion 15 can "block" the external light from entering the touch panel module from the side surface, so as to prevent the white line at the edge of the touch panel from being visualized, as shown in fig. 3. When the lcd module 14 is turned on, some light will be emitted from the sidewall of the color filter panel 142, and the light will be blocked and absorbed by the light-shielding material on the outer side, if "a little" light cannot be absorbed, the light intensity of the light will be reduced by half when the light passes through the upper polarizer 12, so as to effectively improve the problem of light leakage and bright line of the lcd module 14, as shown in fig. 4. In summary, it can be seen that the touch screen structure 1 disclosed by the present invention can effectively overcome the defects of light leakage and easy edge viewing in the narrow frame design.
The present invention has been made in view of the above-mentioned detailed description, and it is an object of the present invention to provide a novel and advantageous method and apparatus for carrying out the method. However, the above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e., the appended claims should be interpreted as covering all equivalent variations and modifications.
