FIG. 1 is a schematic diagram of a touch module according to an embodiment of the invention;
referring to fig. 1, in order to solve the above-mentioned problems, in an embodiment of the invention, a touch module 30 is provided, the touch module 30 is used for being stacked on a display panel 10 for sensing a touch action, and the display panel 10 can display images according to instructions of the touch action.
The display panel 10 includes a driving device for inputting a driving current to the display device to control the display device to emit light, and a display device stacked with the driving device. In some embodiments, the display device includes a first electrode, a second electrode, and an organic light emitting layer, where the organic light emitting layer is located between the first electrode and the second electrode, one of the first electrode and the second electrode is a cathode, and the other of the first electrode and the second electrode is an anode, and specifically, the polarities of the first electrode and the second electrode may be set correspondingly according to the requirement, which is not limited herein. In this manner, the organic light emitting layer is located between the cathode and the anode, and electrons injected from the cathode and holes injected from the anode are combined with each other in the organic light emitting layer to form excitons, and light is emitted when the excitons release energy, thereby realizing the display function of the display panel 10. It will be appreciated that in other embodiments, the display panel 10 may have other display structures, which are not limited herein.
The touch module 30 includes a touch layer 32, and the touch layer 32 has a touch electrode 321 for sensing a touch action. In general, the touch electrode 321 is a metal layer capable of conducting electricity, such as a metal mesh, and the shape of the mesh may be a diamond mesh or a square mesh. In addition, the touch electrode 321 is manufactured through processes such as coating, developing and etching, and the position of the touch electrode is different from the haze of other positions of the touch module 30, which may make the brightness of the area corresponding to the touch electrode 321 on the display panel 100 bigger, and further, the trace of the touch electrode 321 is displayed when the display panel 100 is lighted.
The touch module 30 further includes a cover layer set 34, the cover layer set 34 is covered on the touch layer 32 for protecting the touch layer 32, and the display panel 100 is viewed by naked eyes from a side of the cover layer set 34 facing away from the touch layer 32, that is, light entering the naked eyes is light emitted from the display module 10 to the cover layer set 34. In order to hide the etching lines of the touch electrode 321, the light transmittance of the cover layer set 34 corresponding to the area of the touch electrode 321 can be reduced, so as to shield the etching lines of the touch electrode 321, and finally, the display panel 100 presents a uniform display effect.
Specifically, the cover layer set 34 is laminated on the touch layer 32 and has a display area, and it is understood that the display area of the cover layer set 34 is not the area where the cover layer set 34 emits light, but the area where the cover layer set 34 corresponds to the light emitting position of the display panel 10. The display area includes a first display area and a second display area outside the first display area, where the front projection of the first display area on the touch layer 32 coincides with the touch electrode 321, and the haze of the first display area is greater than the haze of the second display area. That is, the projection of the touch electrode 321 towards the cover plate layer set 34 coincides with the first display area, and the light transmittance of the first display area is smaller than that of the second display area. Equivalently, the shape of the first display area corresponds to the shape of the touch electrode 321 in a matching manner, for example, the shape of the touch electrode 321 is a diamond grid, and the first display area is correspondingly arranged as a diamond grid with the shape and the size consistent with those of the touch electrode 321; if the touch electrode 321 is square, the first display area is correspondingly set to square with the same shape and size as the touch electrode 321. Thus, the shape of the first display area of the cover plate layer group 34 is matched with the shape of the touch electrode 321, and the first display area has higher haze and lower light transmittance, and can shield etching lines formed at the touch electrode 321, so that when the display panel 100 is observed by naked eyes, the brightness of the display area is uniform, and the final display effect is better.

And, set up the shadow layer 347 of eliminating between apron 341 and touch-control layer 32, make the shadow layer 347 of eliminating correspond the partial haze of first display area great, the shadow layer of eliminating 347 corresponds the partial haze of second display area less to through the shadow layer of eliminating 347 corresponding the etching line that the part of first display area sheltered from touch-control electrode 321 department formed, make final display effect more even. It is to be understood that the portion of the shadow eliminating layer 347 corresponding to the second display area may be a transparent layer, or another film layer with lower haze may be formed on the portion of the shadow eliminating layer 347 corresponding to the second display area, or the portion of the shadow eliminating layer 347 corresponding to the second display area may not form a film layer when the shadow eliminating layer 347 is formed, so long as the haze of the shadow eliminating layer 347 corresponding to the second display area is higher.
In some embodiments, a shadow layer 347 is disposed on a surface of the cover 341 facing the touch layer 32, so as to cover the etching lines by the shadow layer 347. Specifically, the shadow eliminating layer 347 may be formed on the cover 341 by processes such as film plating, exposure, development and etching, for example, a groove may be etched in the first display area on the surface of the cover 341 facing the touch layer 32, and a material with a haze greater than that of the second display area is filled in the groove, so that the shadow eliminating layer 347 is formed on the surface of the cover, so that the thickness of the cover layer set 34 is not increased.
