Abstract
The present invention relates to touch-screen button technical field, and in particular to a kind of touch-screen button back lighting device and preparation method.Shown for touch-screen, button is on the cover plate of touch-screen, including LED and light guide ink layer, solve the problems, such as that key-press backlight is dazzling and light guiding film is bonded off normal, press key backlight device uses ink layer as light-conductive media, directly in cover plate back side key zone ink for screen printing layer, so that the LED lamplight passed through is soft dim uniformly without dazzling, the fitting tolerance issues of tool and artificial fitting light guiding film are avoided, save tool and cost of labor, prevent to be bonded bad caused by off normal.
Description
Technical field
The present invention relates to touch-screen button technical field, and in particular to a kind of touch-screen button back lighting device and making side
Method.
Background technology
As shown in figure 1, button 3 is often provided with the cover plate 1 of the touch-screen such as mobile phone, flat board or Vehicular display device,
Button 3 is equipped with LED 4 below, and when our hands touch button 3, LED 4 lights, it can be seen that the button effect after lighting
Fruit.It is about 7-10 μm, both thin and saturating because the profile and color of button 3 are made by ink for screen printing, plus the brightness of LED 4
Height, if without any processing, the light come is appeared at button 3 can be very dazzling, has a strong impact on Consumer's Experience effect.
Normal practice is that (the cover plate back side) pastes a light guiding film 2 under button 3 at present, and the light that LED is sent is by guide-lighting
Become uniform after film 2, it is not dazzling.But need to use tool to attach during patch light guiding film 2, artificial fitting, and fitting be present
Tolerance, misoperation are easily caused fitting off normal, and because light guide sheet has certain thickness, some light will be from the side of light guide sheet
Appear, here it is the light leakage phenomena being commonly called as in industry.
The content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of touch-screen button back lighting device and preparation method, its
Purpose is, there is provided a kind of back lighting device that can provide soft light source, by the back lighting device, it is dazzling to solve key-press backlight
The problem of off normal being bonded with light guiding film.
The present invention provides a kind of touch-screen button back lighting device, shows for touch-screen button, is set on the cover plate of touch-screen
There is button, it is characterised in that including：
LED, it is located at button back side correspondence position；
Light guide ink layer, it is the light element of the LED, and the light guide ink layer is attached at the described of the cover plate
The key area back side.
As further improvement of the invention, the material of the light guide ink layer is milky white color ink.
Improved as of the invention further, the light guide ink layer for the milky white color ink of 1-3 layers.
As further improvement of the invention, the periphery of the light guide ink layer exceedes the periphery 0.3mm- of the button
1.0mm。
As further improvement of the invention, the touch-screen is provided with several buttons, and the back side of each button is corresponding
Position is provided with a LED, and the light element of all LEDs is a strip ink for screen printing layer.
The present invention also provides a kind of touch-screen button back lighting device preparation method, including：
Step 1, the cover plate provided with the button is prepared；
Step 2, in the region of button described in the cover plate back side, the milky white color ink of silk-screen predetermined number of layers, formed guide-lighting
Ink layer；
Step 3, the LED is fitted on the light guide ink layer.
As further improvement of the invention, predetermined number of layers described in step 2 is 1-3 layers.
The present invention has the advantages that：The press key backlight device of the present invention using ink layer as light-conductive media, directly
It is connected on cover plate back side key zone ink for screen printing layer so that the LED lamplight of transmission is soft dim uniformly without dazzling, avoids tool
With the fitting tolerance issues of artificial fitting light guiding film, tool and cost of labor are saved, prevents to be bonded bad caused by off normal.

Embodiment
Below in conjunction with the accompanying drawings, and specific embodiment is described in further detail to the present invention.
Embodiment 1, as shown in Figure 3,4, a kind of touch-screen button back lighting device, shown for touch-screen button, touch-screen
Cover plate 1 be provided with button 3, it is characterised in that including：
LED 4, it is located at the back side correspondence position of button 3；
Light guide ink layer 5, it is the light element of LED 4, and light guide ink layer 5 is attached at the region of button 3 back of the body of cover plate
Face.For the light stopped and scattering LED lamp 4 is sent, the material of light guide ink layer 5 is milky white color ink, light guide ink layer 5
For the milky white color ink of 1-3 layers, ink is thicker, and transparency is lower, and the LED lamplight of transmission is more dim, and atomizing effect is better.
The material of light guide ink layer 5 is milky white color ink.
Light guide ink layer 5 for the milky white color ink of 1-3 layers.
The periphery of light guide ink layer 5 exceedes the periphery 0.3mm-1.0mm of button 3.
Touch-screen is provided with several buttons 3, and the back side correspondence position of each button 3 is provided with a LED 4, all LED
