Description

Technical Field

[0001] The present application relates to an electronic device, and in particular to a touch panel structure. Background Art

[0002] Touchpads are one of the input devices and have been widely used in notebook computers. In order to meet the needs of consumers, luminous touchpads have also been developed.

[0003] Generally speaking, a touchpad can be defined as a touch area and a non-touch area. In order to ensure that the light from the touchpad's light source only passes through the touch area of ​​the touchpad, the touch area and the non-touch area of ​​the touchpad have different structures. The different structures cause the touch area to have a different reflectivity than the non-touch area when it is not emitting light, resulting in color difference, which leads to a poor visual experience for users.

[0004] Therefore, how to propose a touch panel structure that can improve the above problems is one of the issues that need to be solved urgently in the art. Summary of the Invention

[0005] The purpose of this application is to overcome the deficiencies in the prior art and to provide a touch panel structure to solve the problem of color difference in the touch panel in the prior art.

[0006] To achieve the above objectives, the present application proposes a touch panel structure embodiment, which includes a cover plate, a backlight assembly, a touch circuit layer, a first optical modulation layer, and a second optical modulation layer. The first optical modulation layer is located between the cover plate and the backlight assembly and has a first reflectivity. The second optical modulation layer is located between the first optical modulation layer and the touch circuit layer, and the second optical modulation layer has a light shielding material on the side facing the touch circuit layer, defining a light transmission area. The second optical modulation layer has a second reflectivity and a first transmittance. The second reflectivity is the same as the first reflectivity, or the first reflectivity is the same as the first transmittance.

[0007] As described above, the touch panel structure embodiment of the present application disposes a second optical modulation layer between the light-shielding material and the first optical modulation layer. The second optical modulation layer and the first optical modulation layer have the same reflectivity or transmittance. This allows the touch area and non-touch area of ​​the touch panel structure to have the same refractive index due to the second optical modulation layer and the first optical modulation layer. Consequently, the touch area and non-touch area of ​​the touch panel structure appear the same color when not emitting light, thereby enhancing the user's visual experience.
