Patent ID: 11287684

Abstract:
A display panel includes a first substrate, a second substrate, active switches, pixel electrodes, a color filter layer, a light-obstructing layer, a control chip and at least one photosensor. The second substrate is disposed opposite to the first substrate. The active switches are disposed on the second substrate, and each of them comprises an electro-conductive channel. The pixel electrodes are disposed on the second substrate and coupled to the active switches. The color filter layer is disposed on the second substrate and corresponded to the pixel electrodes. The light-obstructing layer is disposed on the first substrate and disposed in correspondence with the electro-conductive channel. The light-obstructing layer covers the electro-conductive channel and is made of an electro-conductive material. The control chip is coupled to the light-obstructing layer. The photosensor is disposed between the first substrate and the light-obstructing layer.
