1. A panel device, comprising:
a touch sensor, disposed in a first area of the panel device and to generate a touch sensing signal;
a first light sensor and a second light sensor, disposed in a second area of the panel device, to respectively sense ambient light and accordingly generate a first light sensing signal and a second light sensing signal;
a first trace, coupled to the first light sensor;
a second trace, coupled to the second light sensor; and
a control circuit, connected to the first trace and the second trace to receive the first light sensing signal and the second light sensing signal at the same time and determine an ambient brightness,
wherein a sensitivity of the first light sensor and a sensitivity of the second light sensor are different.
