The present invention relates to a field of display panel, and more particularly to a touch control display panel and a display device.
Generally, a touch control display panel includes a touch control conductive film and a liquid crystal display module. In a current touch control display panel, the touch control conductive film has a circuit layer for transmitting the touch signal, and the circuit layer is usually disposed on a side of the touch control conductive film facing the liquid crystal display module.
Referring to
A touch control display panel is provided to solve the problems like that when the touch control conductive film is attached and bonded to the liquid crystal display module, there are air bubbles at the edge of the crystal display module, which results in operation difficulty.
A touch control display panel includes a display module and a touch control conductive film, and the display module and the touch control conductive film are sequentially disposed, and a surface of the display module includes an active region and an inactive region, and the display module includes a substrate, a circuit layer, and a display functional layer which are sequentially disposed, and a sum of an area of the active region and an area of the inactive region is equal to an area of the touch control conductive film.
In one embodiment, the circuit layer is only disposed in the active region.
In one embodiment, the functional layer includes a liquid crystal display functional layer.
In one embodiment, the functional layer includes an organic light emitting diode (OLED) functional layer.
In one embodiment, the inactive region can be cut.
In one embodiment, the circuit layer is disposed on the substrate, the display functional layer is disposed on the circuit layer, and the touch control conductive film is disposed on the display functional layer.
In one embodiment, touch control display panel further includes a glass cover disposed above the touch control conductive film.
In one embodiment, an area of the glass cover is equal to an area of the touch control conductive film.
In one embodiment, an area of the glass cover is greater than an area of the touch control conductive film.
A touch control display device is further provided to include a main body and the touch control display panel according to the embodiments, and the touch control display panel is disposed on the main body.
The touch control display panel according to one embodiment of the present invention increases the area of the inactive region around the display module based on the size of the touch control conductive film, and the area of the inactive region around the display module is identical to the touch control conductive film. Therefore, the attaching and bonding yield of the touch control conductive film and the display module are increased, and the touch control conductive film and the glass cover are not required to be attached together, thereby achieving the purpose of reducing weight and cost.
In order to more clearly illustrate embodiments or technical solutions in the present invention, the drawings used in the description of the embodiments or current technology will be briefly described below. Obviously, the drawings in the following description are merely some embodiments of the present invention. A person skilled in the art may also obtain other drawings without any creative efforts.
The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled persons without creative efforts in the art based on the embodiments of the present invention are within the scope of the present invention.
The specific structure and function disclosed are merely representative and are for the purpose of describing exemplary embodiments of the invention. The present invention may, however, be embodied in many alternative forms and should not be construed as being limited only to the embodiments set forth herein.
In first embodiment, the touch control conductive film has a circuit layer for transmitting the touch signal in current touch control display panels, and the circuit layer is usually disposed on a side of the touch control conductive film facing the liquid crystal display module.
The overall area of the touch control conductive film is larger than the area of liquid crystal display module due to peripheral wire of the touch control conductive film. In addition, the touch control conductive film is a flexible substrate, and when the touch control conductive film is attached and bonded to the liquid crystal display module, there are problems such as air bubbles at the edge of the crystal display module, which results in operation difficulty. Thus, the touch control conductive film can only be attached and bonded to the glass cover. Furthermore, the frame area of the liquid crystal display panel is too small, so it cannot be bonded to the touch module. For the above reasons, current capacitive touch control screens are all provided with a glass cover, so that the weight and cost cannot be reduced.
In one embodiment, a touch control display panel is provided. Referring to
The liquid display module 1 includes an active region 11 and an inactive region 12, and a secondary cutting can be performed on the inactive region 12.
The circuit layer 102 is only disposed in the active region 11, and a secondary cutting can be performed on the inactive region 12. There is no circuit layer in the inactive region 12, otherwise it will cause abnormalities when the inactive region 12 is cut.
The substrate 1 is a polyimide (PI) film, which is used as a substrate of the liquid crystal display module 1. The polyimide film is a film-type insulating material with better performance in the world, and has strong tensile strength. It is obtained by polycondensation and casting of pyromellitic dianhydride and diaminodiphenyl ether in a strong polar solvent to form a film and then the film is aminated.
In the embodiment, the display functional layer is a liquid crystal display functional layer. In other embodiments, the display functional layer may also be an organic light emitting diode display functional layer, which may be adopted as needed, and is not limited herein.
A sum of an area of the active region 11 and an area of the inactive region 12 is equal to an area of the touch control conductive film 2. Therefore, it can avoid that the peripheral wire of the touch control conductive film is floated in the prior art.
The attaching and bonding yield of the touch control conductive film and the display module are increased, and the touch control conductive film and the glass cover are not required to be attached together, thereby achieving the purpose of reducing weight and cost.
In second embodiment, referring to
In other embodiments, an area of the glass cover is greater than an area of the touch control conductive film, and it is not limited herein.
The touch control display panel according to one embodiment of the present invention increases the area of the inactive region around the display module based on the size of the touch control conductive film, and the area of the inactive region around the display module is identical to the touch control conductive film. Therefore, the attaching and bonding yield of the touch control conductive film and the display module are increased.
In third embodiment, a touch control display device includes a main body, and the touch control display panel of the first embodiment is disposed on main body.
The touch control display panel according to one embodiment of the present invention increases the area of the inactive region around the display module based on the size of the touch control conductive film, and the area of the inactive region around the display module is identical to the touch control conductive film. Therefore, the attaching and bonding yield of the touch control conductive film and the display module are increased, and the touch control conductive film and the glass cover are not required to be attached together, thereby achieving the purpose of reducing weight and cost.
In the above, the present application has been described in the above preferred embodiments, but the preferred embodiments are not intended to limit the scope of the invention, and a person skilled in the art may make various modifications without departing from the spirit and scope of the application. The scope of the present application is determined by claims.
