Light emitting diode display panel |
摘要 |
A light emitting diode display panel includes a control circuit and a plurality of pixels arranged in a matrix. Each of the pixels includes a first light source and a first light sensing element. The first light sensing element receives a first optical signal from a lighting pen and generates a first control signal to the control circuit. According to the first control signal, the control circuit turns on the first light source in the pixel. The pixels further comprise a first polarizer covering the first light sensing element. When the lighting pen emits the first optical signal, a polarization direction of the light from the lighting pen is parallel to a polarization direction of the first polarizer. Therefore, the first optical signal can pass through the first polarizer and be received by the first light sensing element. |
