  • Patent number: 11648627
    Abstract: A touch display device is provided in some embodiments of the present disclosure, including a transparent cover, a patterned touch sensing film layer, a light-shielding layer, and a UV-blocking layer. The patterned touch sensing film layer covers a first surface of the transparent cover. The light-shielding layer is located between the transparent cover and the patterned touch sensing film layer. The UV-blocking layer prevents UV from irradiating the light-shielding layer. The UV-blocking layer is located between the light-shielding layer and the patterned touch sensing film layer and covers the light-shielding layer. A method of forming a touch display device is also provided. The touch display device and formation method thereof provided in some embodiments avoid the injury of the light-shielding layer caused by the laser by disposing of the UV-blocking layer in the single-side electrode structure, which replaces the wet etching steps and decreases the cost of the etching steps.

The spring member also includes a second arm that biases a first force electrode toward the housing and allows the first force electrode to move toward a second force electrode when a force is applied to the force input surface. A non-binary amount of the force is determinable using a change in a mutual capacitance between the first force electrode and the second force electrode. The mutual capacitance between the first force electrode and the second force electrode may be measured upon detecting a touch using the touch sensor.
