Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a touch display cover plate and a touch display module. Background Art

[0002] With the development of touch technology, embedded In-cell TFT (Thin Film Transistor) has become the mainstream of TFT touch display technology. TFT touch display devices using embedded In-cell touch technology usually have static electricity problems. In order to solve the static electricity problem, it is necessary to plate a high-resistance film on the surface of the TFT panel. Generally, the TFT panel is thinned before the coating process. Alternatively, a low-resistance polarizer is used, and conductive materials are added to the PSA (Pressure Sensitive Adhesive) of the polarizer. However, the cost of plating a high-resistance film on the surface of the TFT panel is high, and the cycle is long, which greatly increases the production cost. The polarizer with conductive materials added to the PSA has poor high-temperature reliability and cannot meet the needs of automotive products. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] Figure 1 is a schematic diagram of the structure of the touch display cover plate of the embodiment of the present application. It should be noted that if there is substantially the same result, the touch display cover plate of the present application is not used as Figure 1 The structure shown is limited. Figure 1 and Figure 2 As shown, the touch display cover plate 10 includes a cover plate body 11, a conductive layer 12, an insulator 13 and a first electrical connector (not shown). The cover plate body 11 has a first surface 111 and a second surface 112 arranged opposite to each other. The first surface 111 of the cover plate body 11 includes a touch portion 1111 and a frame portion 1112, and the frame portion 1112 is located at the periphery of the touch portion 1111. The conductive layer 12 covers the second surface 112 of the cover plate body 11. The insulator 13 is fixed to the conductive layer 12, and the insulator 13 is located on the side of the conductive layer 12 away from the cover plate body 11, and the insulator 13 is arranged corresponding to the frame portion 1112. The first electrical connector is penetrated by the insulator 13, and both ends of the first electrical connector are exposed on the surface of the insulator 13, and one end of the first electrical connector is connected to the conductive layer 12, so that the conductive layer 12 can be grounded through the first electrical connector.

[0026] In the embodiment of the present application, the cover body 11 has a first surface 111 and a second surface 112 arranged opposite to each other. The first surface 111 of the cover body 11 includes a touch portion 1111 and a frame portion 1112 located outside the touch portion 1111. The conductive layer 12 covers the second surface 112 of the cover body 11, and the conductive layer 12 is grounded through a first electrical connector, thereby solving the static electricity problem of display and touch. In the embodiment of the present application, the conductive layer 12 is arranged on the cover body 11, which effectively reduces the production cost, and has high high temperature reliability, which can effectively meet the needs of vehicle-mounted products.

[0027] In some embodiments, the cover body 11 is made of tempered glass. The tempered glass cover body 11 is not only strong, impact-resistant and scratch-resistant, but also has good light transmittance, thereby effectively protecting the touch display screen 20 and improving the service life and product quality of the touch display module.

[0028] It should be noted that, in other embodiments, the cover plate body 11 may also be made of other materials, which will not be elaborated herein.

[0029] In some embodiments, the conductive layer may be a high-resistance conductive layer. Specifically, the surface resistance of the conductive layer 12 may be 10 7 Ω / sq-10 12 Ω / sq, which not only achieves anti-static effect, but also does not block the touch function, which can effectively improve the user experience.

[0030] In some embodiments, the conductive layer 12 includes an ITO (Indium Tin Oxide) layer. The ITO layer not only has high conductivity and high transparency, but also has good chemical stability and mechanical strength, thereby further improving the performance of the touch display cover plate 10.

[0031] As an example, the conductive layer 12 may be coated on the entire second surface 112 of the cover body 11 , thereby more effectively solving the static electricity problem.

[0032] It should be noted that, in other embodiments, the conductive layer 12 may also include other materials, which will not be described in detail here.

[0033] In some embodiments, from the user's perspective, the touch area 1111 of the cover body 11 appears as a transparent window, and the frame area 1112 appears as a black non-transparent area. Figure 1 The insulator 13 may be a black insulating ink screen-printed around the cover body 11 coated with the conductive layer 12, which not only has a good insulating effect and is easy to produce, but also can make the frame portion 1112 of the cover body 11 appear black.

[0034] It should be noted that, in other embodiments, the insulator 13 may also be made of other processes or other materials, and the insulator 13 may also be other colors, which will not be elaborated here.

[0035] In some embodiments, the first electrical connector may be a conductive ink. Specifically, the first electrical connector may be made of carbon paste, which not only has a good conductive effect, so that the conductive layer 12 can be effectively grounded, but also has a black color, which matches the color of the insulator 13. The black first electrical connector is inserted into the black insulator 13, which can effectively avoid color difference and further improve the appearance quality of the product.

[0036] It should be noted that, in other embodiments, the first electrical connector may also be made of other materials, and the first electrical connector may also be other colors, which will not be elaborated herein.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 The insulator 13 is formed with a conductive via 131 penetrating the insulator 13, which ensures the insulation effect while facilitating the first electrical connector to be inserted into the conductive via 131. In addition, the insulator 13 is formed with a plurality of conductive vias 131, each of which is penetrated by a first electrical connector, so that the conductive layer 12 can be grounded more stably and effectively through the first electrical connector.

[0038] As an example, please refer to Figure 1 There are three conductive vias 131 on the insulator 13, and each conductive via 131 is filled with carbon paste to form a first electrical connector, which not only has a simple structure, but also allows the conductive layer 12 to be stably and effectively grounded through the first electrical connector.

[0039] It should be noted that the above examples are only for illustration, and the present application does not limit the specific number of the conductive vias 131 of the insulator 13 .

[0040] In some examples, the diameter of the conductive via 131 is 0.2 mm-0.6 mm, which can effectively ensure not only the insulation effect of the insulator 13 but also the conductivity effect of the first electrical connector.

[0041] In some embodiments, one end of the first electrical connector is connected to the conductive layer 12, and the other end of the first electrical connector is connected to the ground wire of the circuit board 22, wherein the circuit board 22 can be the circuit board 22 of the touch display screen 20, which not only makes the overall structure more compact, but also can effectively solve the static electricity problem.

[0042] Please refer to Figure 3 The embodiment of the present application provides a touch display module, including the touch display cover plate 10 as described in any of the above embodiments. As an example, the touch display module can be applied to consumer electronics, vehicle display, automatic control and other fields.

In the embodiment of the present application, the conductive layer 12 is arranged on the cover body 11, which effectively reduces the production cost, and has high high temperature reliability, can effectively improve the performance of the touch display module, and expand the application range of the touch display module.

[0044] In some embodiments, please refer to Figure 3 The touch display module also includes a touch display screen 20, which includes a body 21 and a circuit board 22, and the circuit board 22 is connected to the body 21. The touch display cover 10 is fixed to the body 21, and the conductive layer 12 is electrically connected to the ground wire of the circuit board 22 through the first electrical connector, which is not only compact in structure, but also can effectively solve the static electricity problem of the touch display module.

[0045] In some embodiments, please refer to Figure 3 The touch display module further includes a second electrical connector 30, which is pasted between the insulator 13 and the circuit board 22, and the conductive layer 12 is electrically connected to the ground line of the circuit board 22 through the first electrical connector and the second electrical connector 30 in sequence. In this embodiment, the second electrical connector 30 is pasted between the insulator 13 and the circuit board 22, which can not only effectively ground the conductive layer 12 through the ground line of the circuit board 22, but also make the connection relationship between the conductive layer 12 and the circuit board 22 more stable. In addition, the second electrical connector 30 is pasted between the insulator 13 and the circuit board 22, which is not only simple in structure, but also easy to install, and effectively improves the assembly efficiency.

[0046] In one embodiment, the second electrical connector 30 may be a conductive double-sided adhesive tape, which can be quickly attached between the insulator 13 and the circuit board 22 , and can also cooperate with the first electrical connector to effectively electrically connect the conductive layer 12 and the circuit board 22 .

[0047] In one example of the present application, the circuit board 22 is a FPC (Flexible Printed Circuit) board. In other embodiments, the circuit board 22 may also be other types of circuit boards, which will not be described in detail herein.

[0048] It should be noted that the present application does not limit the specific structure of the main body 21 and the circuit board 22 , and the touch screen 20 may be an existing touch screen, which will not be described in detail herein.

[0049] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
