Technical Field

[0001] The invention relates to a touch panel, and in particular to a luminous touch panel. Background Art

[0002] Touchpads are widely used in electronic products. For example, touchpads can be used in smart phones to allow users to quickly execute set actions or open set applications. Alternatively, touchpads can be used in laptops to replace the mouse function.

[0003] In order to further enhance the convenience of the touchpad, an application pattern can be set on the touchpad. When the application pattern is touched, the system will open the corresponding application. However, for users, there is still room for improvement in the design of the touchpads currently on the market. Summary of the invention

[0004] The invention provides a luminous touch panel which can provide intuitive operation functions.

[0005] An embodiment of the present invention provides a light-emitting touch panel, which includes a protective layer, a touch module, a lens array layer and a light source module. The touch module is arranged between the protective layer and the lens array layer. The lens array layer is arranged between the touch module and the light source module. The light source module is used to generate a plurality of light-emitting patterns. Light of the light-emitting pattern passes through the lens array layer, the touch module and the protective layer to form a plurality of stereoscopic images.

[0006] Based on the above, in one embodiment of the present invention, the light-emitting touch panel generates multiple light-emitting patterns through the light source module, and the light of the light-emitting pattern passes through the lens array layer, the touch module and the protective layer to form multiple stereoscopic images. Therefore, the system can present stereoscopic images by emitting light, so that the user can still operate the light-emitting touch panel in an environment with low lighting. Moreover, the system can present operable actions or openable applications through stereoscopic images, thereby further improving the user's adaptability to using the light-emitting touch panel.

[0012] Figure 1 FIG. 1 is a schematic diagram of applying a light-emitting touch panel to an electronic device according to an embodiment of the present invention. Figure 2 is a cross-sectional schematic diagram of a light-emitting touch panel according to an embodiment of the present invention. Figure 1 and Figure 2 An embodiment of the present invention provides a light-emitting touch panel 100, which is suitable for application in an electronic device 10. The electronic device 10 is, for example, a notebook computer, a smart phone, or a keyboard, but the present invention is not limited thereto.

[0013] In this embodiment, the light-emitting touch panel 100 includes a protective layer 110, a touch module 120, a lens array layer 130 and a light source module 140. The protective layer 110 is a flat plate made of transparent materials such as plastic and glass. In one embodiment, the protective layer 110 can be a light-transmitting flat plate that has been atomized.

[0014] In this embodiment, the touch module 120 is disposed between the protective layer 110 and the lens array layer 130. The lens array layer 130 is disposed between the touch module 120 and the light source module 140. The light source module 140 is used to generate a plurality of light patterns. The light of the light pattern passes through the lens array layer 130, the touch module 120 and the protective layer 110 to form a plurality of stereoscopic images SI.

[0015] In detail, in the present embodiment, the light source module 140 includes a pattern layer 142, a light guide layer 144, and a light source 146. The pattern layer 142 is disposed on a side of the lens array layer 130 relative to the touch module 120. The pattern layer 142 is disposed between the lens array layer 130 and the light guide layer 144. The pattern layer 142 includes a plurality of patterns PT. The pattern layer 142 has a light-transmitting area TA and a non-light-transmitting area NTA, and the pattern P is disposed in the light-transmitting area TA.

[0016] For example, the non-light-transmitting area NTA may be black opaque ink. Alternatively, the color of the non-light-transmitting area NTA may be the same as the color of the electronic device 10, so that the luminous touch panel 100 has visual consistency with the electronic device 10 when not emitting light.

[0017] In the present embodiment, the light source 146 is, for example, a light-emitting diode (LED) light source or other suitable light source. The light source 146 is disposed next to the light guide layer 144 and is used to emit an illumination light beam IL. The light guide layer 144 is, for example, a light guide film or a light guide plate. The illumination light beam IL is first transmitted to the light guide layer 144, and then transmitted to the pattern PT through the light guide layer 144 to generate a light-emitting pattern. In other words, when the illumination light beam IL is transmitted to the pre-designed pattern PT to generate a light-emitting pattern, these light-emitting patterns are transmitted to the left eye or right eye of the viewer through the lens array layer 130, so that the viewer visually produces the effect of seeing a stereoscopic image SI. Figure 1 For example, the stereoscopic image SI may be play, forward, backward, increase volume, decrease volume, etc. In another embodiment, the stereoscopic image SI may also be presented in the form of text.

[0018] In order to improve the visual consistency between the luminous touch panel 100 and the electronic device 10 when not emitting light, in the present embodiment, the light transmittance of the light-transmitting area TA is preferably less than 70%.

[0019] In this embodiment, the luminous touch panel 100 further includes a controller 150. The controller 150 is electrically connected to the touch module 120 and the light source module 140. The controller 150 controls the light source module 140 to generate a luminous pattern and generates a corresponding function signal FS when a position P corresponding to the stereoscopic image SI on the luminous touch panel 100 (protective layer 110) is touched.

[0020] In this embodiment, the controller 150 includes, for example, a microcontroller unit (MCU), a central processing unit (CPU), a microprocessor (microprocessor), a digital signal processor (DSP), a programmable controller, a programmable logic device (PLD), or other similar devices or a combination of these devices, and the present invention is not limited. In addition, in one embodiment, each function of the controller 150 can be implemented as a plurality of program codes. These program codes will be stored in a memory, and the controller 150 will execute these program codes. Alternatively, in one embodiment, each function of the controller 150 can be implemented as one or more circuits. The present invention is not limited to implementing each function of the controller 150 in software or hardware.

[0021] Figure 3 Schematic diagram of the viewing angle of a 3D image on a light-emitting touch panel according to an embodiment of the present invention. Figure 3In this embodiment, the viewing angle θ of the stereoscopic image SI is less than or equal to 60 degrees.

[0022] Based on the above, in one embodiment of the present invention, the luminous touch panel 100 includes a protective layer 110, a touch module 120, a lens array layer 130 and a light source module 140. The light source module 140 is used to generate a plurality of luminous patterns, and the light of the luminous patterns passes through the lens array layer 130, the touch module 120 and the protective layer 110 to form a plurality of stereoscopic images SI. Therefore, the system can present the stereoscopic image SI in a luminous manner, so that the user can still operate the luminous touch panel 100 in an environment with low lighting. Moreover, the system can present operable actions or openable applications through the stereoscopic image SI, which can further enhance the user's adaptability to using the luminous touch panel 100.

[0023] Figure 4 is a schematic diagram of a light-emitting touch panel according to an embodiment of the present invention. Figure 4 , the luminous touch panel 100A and Figure 2 The controller 150 is similar to the luminous touch panel 100 of FIG. 1 , and the main differences are as follows. In the present embodiment, the protective layer 110A has a plurality of non-luminous patterns NPT on a side relative to the touch module 120. When a position corresponding to the non-luminous pattern NPT on the luminous touch panel 100A (protective layer 110A) is touched, the controller 150 generates a corresponding function signal FS. For example, the non-luminous pattern NPT may be an illustration or name of a commonly used application (such as a browser, calculator software, video software, etc.). When a user touches the non-luminous pattern NPT, the system may open the corresponding application.

[0024] Figure 5 is a cross-sectional schematic diagram of a light-emitting touch panel according to an embodiment of the present invention. Figure 5 , the luminous touch panel 100B and Figure 2 The illuminated touch panel 100 or Figure 4 The light source module 140B is similar to the light emitting touch panel 100A, and the main differences are as follows. In this embodiment, the light source module 140B is a display module, such as a liquid crystal display, an organic light emitting diode (OLED) display, etc. In other words, the display module can directly generate a light pattern. Therefore, the system can change the stereoscopic image SI generated by the light emitting touch panel 100B by changing the light pattern; or, the stereoscopic image SI generated by the light emitting touch panel 100B can change with different applications opened by the system.

[0025] In summary, in one embodiment of the present invention, the luminous touch panel includes a protective layer, a touch module, a lens array layer and a light source module. The light source module is used to generate a plurality of luminous patterns, and the light of the luminous patterns passes through the lens array layer, the touch module and the protective layer to form a plurality of stereoscopic images. Therefore, the system can present a stereoscopic image by luminescence, so that the user can still operate the luminous touch panel in an environment with low lighting. Moreover, the system can present operable actions or openable applications through stereoscopic images, which can further enhance the user's adaptability to using the luminous touch panel.
