In this article, the term "above" or "below" may refer to a part being located above or below another part in close proximity and a third part between a part and another part and a part being located above or below it relative to another part. In the accompanying drawings, the same reference numerals will be used to indicate the same parts, and in addition, for clarity, some parts in the accompanying drawings may not be shown to scale.

[0030] Combine the following Figures 1 to 4 A touch display module for a transmitter (hereinafter also referred to as “touch display module” for short) according to a first exemplary embodiment of the present application is described in detail. Figure 1 is an exploded perspective view showing a touch display module according to a first exemplary embodiment of the present application, and Figure 2 is a cross-sectional view showing a touch display module according to a first exemplary embodiment of the present application. Figure 1 and Figure 2 As shown, the touch display module 1 according to the first exemplary embodiment of the present application may include a cover plate 10, a sensing layer 30 disposed under the cover plate 10, and a display unit 50 disposed under the sensing layer 30, wherein a first optically transparent adhesive layer 20 may be adhered between the cover plate 10 and the sensing layer 30, and a second optically transparent adhesive layer 40 may be adhered between the sensing layer 30 and the display unit 50, so that the cover plate 10, the sensing layer 30 and the display unit 50 form an integrated touch display module 1 and the display unit 50 can clearly display information through the various components above. Figure 1 As shown, the area of ​​the cover plate 10 and the sensing layer 30 can be larger than the area of ​​the display unit 50, that is, the cover plate 10 and the sensing layer 30 located above the display unit 50 can cover the entire display unit 50. When using the touch display module 1, the user can input instructions by touching any area of ​​the entire cover plate 10, and the sensing layer 30 can sense the touch instructions input on the entire cover plate 10 and generate corresponding sensing signals, and then the display unit 50 provides display information to the user based on the sensing signals.

[0031] In conventional touch display modules, usually only the touch buttons located at the four corners of the periphery of the display unit can be operated, which makes the user's operation inconvenient and the user experience is poor. In the touch display module 1 according to the first exemplary embodiment of the present application, since the sensing layer covers the entire display unit, the user can perform touch operations on the entire area of ​​the cover plate 10, which greatly increases the touch operation area and thus significantly improves the user's experience. That is to say, compared with the conventional touch display module, the touch display module 1 according to the first exemplary embodiment of the present application can greatly increase the area of ​​the touch operation area while the overall outer dimensions are roughly the same as those of the conventional touch display module, thereby providing a touch display module that is easy for the user to operate in a compact structure.

[0032] like Figure 1 As shown, the cover plate 10 may include a first area 12 and a second area 14, the first area 12 may be arranged in the center of the cover plate 10 and be optically transparent, and the second area 14 may be arranged at the periphery of the first area and printed with static buttons. The cover plate 10 may be formed of glass, and static buttons may be formed in the second area 14 of the cover plate by silk-screening the glass. The shape and position of the transparent first area 12 may correspond to the shape and position of the display unit 50, so that the information on the display unit 50 can be clearly and completely displayed in the first area 12 located in the center of the cover plate. Preferably, the area of ​​the first optically transparent adhesive layer 20 may be the same as the area of ​​the cover plate 10 and the sensing layer 30, and the area of ​​the second optically transparent adhesive layer 40 may be the same as the area of ​​the display unit 50, so that the cover plate 10, the sensing layer 30 and the display unit 50 can be firmly bonded together.

[0033] For example, when using the touch display module 1, the user can not only operate by touching the static buttons located in the second area 14, but also operate by touching the power-on display menu located in the first area 12, so that the touch function can be realized on the entire cover 10, thereby greatly increasing the area of ​​the touch operation area and facilitating user operation.

[0034] Reference Figure 1 , the outer side of the sensing layer 30 may be connected to the first signal transmission unit 38, and the outer side of the display unit 50 may be connected to the second signal transmission unit 58. Figure 2 As shown, in the assembled state, the first signal transmission part 38 can be connected with the second signal transmission part 58. Exemplarily, the first signal transmission part 38 and the second signal transmission part 58 can be formed as a strip-shaped flexible printed circuit (FPC), and the flexible printed circuit can be connected together by pressure welding.

[0035] The sensing layer 30 may include a glass substrate and an electrode array arranged on the glass substrate. Figure 3 The electrode array may be formed of a transparent conductive material and include a first electrode group 32 and a second electrode group 34 arranged in a cross pattern. The first electrode group 32 may include a plurality of first electrodes extending along a first direction, and the first electrodes are spaced apart from each other by an equal distance in a second direction perpendicular to the first direction. The second electrode group 34 may include a plurality of second electrodes extending along a second direction, and the second electrodes are spaced apart from each other by an equal distance in the first direction.

[0036] The transparent conductive material may include, for example, indium tin oxide (ITO) and the sensing layer 30 may be formed as a capacitive sensing layer. Specifically, when the user's finger touches the cover plate 10, it affects the coupling between the two electrodes on the sensing layer 30 located near the touch point, thereby changing the capacitance between the two electrodes. Based on the capacitance change data, the processor can calculate the coordinates of the corresponding touch point, and then determine the function that the user expects to achieve by touching a specific position based on the unique functions corresponding to each pre-set coordinate.

[0037] The display unit 50 may include, for example, a liquid crystal display LCD, a light emitting diode display LED or any other suitable display.

[0038] In the touch display module 1 for a transmitter according to the first exemplary embodiment of the present application, the user can use the entire area of ​​the cover plate 10 for touch operation, which greatly increases the area of ​​the touch area compared to conventional touch display modules, and significantly improves the user's convenience. In addition, the touch display module 1 is easy to manufacture and assemble, and can simply form a compact integrated structure, saving processing costs.

[0039] Refer to the following Figure 4 and Figure 5 The touch display module according to the second exemplary embodiment of the present application is described below. Similar to the touch display module according to the first exemplary embodiment of the present application, the touch display module 1A according to the second exemplary embodiment of the present application may include a cover plate 10, a first optically transparent adhesive layer 20, a sensing layer 30, a second optically transparent adhesive layer 40, and a display unit 50. In addition, as Figure 4 As shown, the touch display module 1A according to the second exemplary embodiment of the present application may further include a support portion 60 , a bracket 70 , and a control board 80 .

[0040] The support portion 60 may be formed with an opening area 62. When assembled, the support portion 60 is arranged to surround the periphery of the display unit 50 and abut against the lower surface of the sensing layer 30 so that the display unit 50 is located in the opening area 62. A bracket 70 may be disposed below the support portion 60 and the bracket 70 may be configured to fix the touch display module 1 to the transmitter (i.e., to other components of the transmitter). Preferably, as Figure 4 As shown, the bracket 70 may include an opening area 72 corresponding to the opening area 62, but the present invention is not limited thereto, and the bracket may not include an opening area. Figure 4 The bracket 70 may also include a first direction ( Figure 4 and a first connecting member 74 extending in a second direction ( Figure 4 The first connector 74 can be connected to the connection hole of the support portion 60 and the second connector 76 can be connected to the connection hole of other components of the transmitter. The control board 80 can be arranged below the bracket 70 and include a processor configured to receive a sensing signal from the sensing layer 30 via the first signal transmission portion 38 and provide display information to the display unit 50 via the second signal transmission portion 58. A connector 33 can be provided below the sensing layer 30, and the connector 33 can extend through the socket 68 of the support portion 60, the socket 78 of the bracket 70, and the socket 88 of the control board 80 respectively to assemble the components into one.

[0041] Figure 5 The figure shows a stereoscopic view of the touch display module in the assembled state according to the second exemplary embodiment of the present application. The touch display module 1A can be easily installed in the transmitter by using the second connecting member 76 arranged on the periphery of the bracket 70, so the touch display module can be conveniently integrated into the transmitter without modifying other components of the transmitter. In addition, the touch display module according to the second exemplary embodiment of the present application can increase the area of ​​the touch area, significantly improving the user's convenience.

[0042] Of course, those skilled in the art should understand that the touch display module according to the present invention can also be applied to various other electronic devices with touch functions. The present invention is not limited to the specific embodiments described and shown in detail herein, and those skilled in the art can make various changes to the exemplary embodiments without departing from the scope defined by the claims.
