Abstract
A panel device includes a touch sensor, a first light sensor and a second light sensor, a first trace, a second trace and a control circuit. The touch sensor is disposed in a first area of the panel device to generate a touch sensing signal. The first light sensor and the second light sensor are disposed in a second area of the panel device to sense ambient light and generate a first light sensing signal and a second light sensing signal. The first trace is coupled to the first light sensor. The second trace is coupled to the second light sensor. The control circuit connects the first trace and the second trace and receives the first light sensing signal and the second light sensing signal at the same time to determine an ambient brightness. Sensitivities of the first light sensor and the second light sensor are different.
