Abstract

An electronic device includes a touch sensing module. The touch sensing module has a transparent area and a non-transparent area, and includes a touch sensing layer, a transparent substrate, a light source module, and a control module. The touch sensing layer has a first side and a second side opposite to each other. The transparent substrate is disposed on the first side. The light source module is disposed on the second side. The light source module emits multiple illumination lights and transmits them to the touch sensing layer. The illumination lights pass through the touch sensing layer and the transparent substrate and are emitted from the transparent area of ​​the touch sensing module. The control module is electrically connected to the touch sensing layer and the light source module, and is used to control the light intensity of the illumination lights according to the position where the touch sensing layer is touched.

Claims

1. An electronic device comprising a touch sensing module, wherein the touch sensing module has a transparent area and a non-transparent area, and includes: A touch sensing layer having a first side and a second side opposite to each other; A transparent substrate is disposed on the first side; A light source module is disposed on the second side, which emits multiple illumination lights that pass through the touch sensing layer and the transparent substrate and are emitted from the transparent area of ​​the touch sensing module; and a control module is electrically connected to the touch sensing layer and the light source module to control the light intensity of the illumination lights according to the position where the touch sensing layer is touched.

2. The electronic device as claimed in claim 1, wherein the light source module comprises: A light guide plate having an input light side and an output light side; And multiple light sources are disposed next to the light guide plate and used to emit the illumination light, wherein the illumination light enters the light guide plate from the light-incident side of the light guide plate, is transmitted in the light guide plate, and is then emitted from the light-exit side of the light guide plate to be transmitted to the touch sensing layer.

3. The electronic device as claimed in claim 2, wherein the light guide plate has a plurality of light-guiding microstructures on the surface of the light-emitting side facing the touch sensing layer.

4. The electronic device as claimed in claim 3, wherein: The light-guiding microstructures are disposed in the non-transparent area of ​​the touch sensing module; or a portion of the light-guiding microstructures are disposed in the transparent area of ​​the touch sensing module.

5. The electronic device of claim 2, wherein the light guide plate has a plurality of light-diffusing microstructures on the surface of the light-incident side facing the light sources.

6. The electronic device as claimed in claim 2, wherein the light source module further comprises: A reflective layer is disposed on at least one surface of the light guide plate.

7. The electronic device of claim 2, wherein the control module is configured to control the luminous intensity of each of the light sources according to the location where the touch sensing layer is touched.

8. The electronic device as claimed in claim 1, further comprising: An ink layer is disposed on the transparent substrate to allow the illumination light to pass through when the light source module emits light, making the touch sensing module transparent, and to make the touch sensing module non-transparent when the light source module does not emit light.

9. The electronic device as claimed in claim 1, further comprising: A motherboard is electrically connected to the control module, wherein the control module is used to transmit the signal of the touch sensing layer being touched to the motherboard, and to directly control the light source module to emit light according to the touch sensing layer being touched.

10. The electronic device as claimed in claim 1, further comprising: A switch module is disposed in the non-transparent area of ​​the touch sensing module and is electrically connected to the touch sensing layer; A conversion circuit board is disposed between the touch sensing layer and the switch module, electrically connected to the switch module and the touch sensing layer, and used to convert the circuit pattern of the touch sensing layer into the circuit pattern of the switch module.

11. The electronic device as claimed in claim 1, further comprising: A frame is disposed on the touch sensing layer and in the non-transparent area of ​​the touch sensing module, wherein the frame has an opening and the extent of the opening defines the extent of the transparent area of ​​the touch sensing module.

12. The electronic device as claimed in claim 1, further comprising: A textured structure layer is disposed on the transmission path of the illumination light emitted from the light source module, so as to receive the illumination light and reflect it to the touch sensing layer so that the illumination light forms a specific pattern.
