Description

Contact panel and touch control display device thereof
Technical field
A kind of touch technology of the utility model system, espespecially a kind of contact panel and touch control display device thereof.
Background technology
Along with the development of touch technology, contact panel is widely used in various electronic product, refer to shown in Figure 12, contact panel as user's input interface of electronic product comprises a cover plate 21 usually, the one touch-control sensing module 22 of fitting with this cover plate 21, and one is arranged at shielding layer 23 between this cover plate 21 and this touch-control sensing module 22, wherein this shielding layer 23 is light tight structure, and be generally arranged on cover plate 21 non-touch-control face to form the non-visible area IVA of a contact panel, wherein, this cover plate 21 of the non-touch-control face system of this cover plate 21 is in the face of the surface of this touch-control sensing module 22.This shielding layer 23 is the metallic circuit structure 221 of covering in touch-control sensing module 22, makes metallic circuit structure 221 not by consumer's finding.
Above-mentioned shielding layer 23 is formed on this cover plate 21 by the processing procedure be coated with or print usually, due to reasons such as processing procedure tolerances, the metallic circuit structure 221 that shielding layer 23 generally will be able to cover than it is much wide, thus make contact panel non-viewing area IVA also can be relatively wide, therefore, prior art is unfavorable for the narrow frame design of contact panel, does not meet the development trend of the narrow frame of contact panel.
Utility model content
Because the shortcoming of prior art, the utility model system provides a kind of touch control display device and contact panel thereof, and it does not have shielding layer, can reduce the scope of non-visible area, designs the contact panel of narrower frame.
The technological means system that the utility model is taked makes this contact panel define a non-visible area and a pair should the visible area of non-visible area, and includes: a cover plate; One sensing module is be arranged at below this cover plate, comprises the pin configuration that is arranged at this non-visible area; And a housing, be this deck side edge coated, this housing be formed with one in order to the hidden portion of the conductor layer of this sensing module hidden, wherein this concealment part defines this non-visible area below this cover plate.
And touch control display device system of the present utility model includes above-mentioned contact panel and a display module, between the sensing module of this display module and this contact panel, cording has one the 3rd bonding coat, to be fitted in below this sensing module by this display module, form this touch control display device.
It can thus be appreciated that contact panel of the present utility model lies on housing and is formed with hidden portion, this pin configuration hidden by this, makes this pin configuration do not seen by user.For this reason, just without the need to arranging the larger shielding layer of processing procedure tolerance to cover this pin configuration, thus the non-viewing area of contact panel can be reduced, the designer of contact panel just can design the contact panel of the narrower frame of frame, to meet the development trend of the narrow frame of contact panel.
