Problems solved by technology
[0003] The above-mentioned touch panel can make the light source pass through the light-guiding film composed of the second black light-shielding film 08, the second white ink layer 07, the light-guiding film 06, the first white ink layer 05, the first black light-shielding film 04, and the double-sided adhesive tape 03. The layer backlights the button graphics, but the above-mentioned touch panel, due to the double-sided adhesive 03, the first black light-shielding film 04 and the first white ink layer 05, makes the light guide layer thicker; and because the double-sided adhesive 03, Both the first black light-shielding film 04 and the first white ink layer 05 are provided with light-transmitting holes, so that after the light-guiding film 06 is attached to the first black light-shielding film 04, it is easy to make the double-sided adhesive tape 03, the first black light-shielding film 04 and the air in the light holes of the first white ink layer 05 enter between the double-sided adhesive tape 03, the first black light-shielding film 04 and the first white ink layer 05, so that the double-sided adhesive tape 03, the first black light-shielding film Bubbles are generated between 04 and the first white ink layer 05, resulting in insensitive touch; and since the double-sided adhesive tape 03, the first black light-shielding film 04 and the first white ink layer 05 are provided with light-transmitting holes, when the light When it is irradiated on the light-transmitting holes on the double-sided adhesive tape 03, the first black light-shielding film 04 and the first white ink layer 05, it is easy to form a halo, thereby affecting the display effect of the button graphics

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Depend on figure 2 As shown, the touch panel of the present invention includes a glass cover 1 , a light guide film 4 , a black light shielding film 6 and a touch module 7 .
[0021] A button area 101 is arranged on the glass cover, and several button graphics are arranged on the button area. A first white ink layer 2 is printed on the back of the button area. A pair of overlapping hollow holes 201 .
[0022] The light guide film is covered on the first white ink layer and is bonded and fixed to the first white ink layer by a transparent double-sided adhesive tape 3 . There are several light guide dots 401, and the transparent double-sided adhesive tape 3 has a light transmittance of at least 80%.
[0023] The black light-shielding film 6 is provided with several first light-transmitting holes 601, and a second white ink la...

The invention discloses a touch control panel. A light guide layer is formed by a black light-shielding film, a second white printing ink layer, a light guide film and a double-faced adhesive tape. The light guide layer is much thinner and causes no bubbles during adhesion, so touch control sensitivity can be improved and key image displaying effect can be enhanced.
Description
technical field [0001] The invention relates to a touch panel. Background technique [0002] State-of-the-art touch panels such as figure 1 As shown, the first black light-shielding film 04, the light-guiding film 06, the second black light-shielding film 08, and the touch module 09 are generally stacked layer by layer on the back of the key area 02 of the glass cover plate 01. The first black light-shielding film 04 The button area 02 of the glass cover plate 01 is bonded by double-sided adhesive tape 03, the surface of the first black light-shielding film 04 that is attached to the light-guiding film 06 is printed with a first white ink layer 05, and the second black light-shielding film 08 The second white ink layer 07 is printed on the surface that is attached to the light-guiding film 06, and the light emitted by the light source is irradiated on the light-guiding film 06 through the light-transmitting hole on the second black light-shielding film 08, and the light-gui...
