Abstract
A touch sensing display including a carrier, a plurality of light emitting devices arranged in an array on the carrier, a driving unit electrically connected to the light emitting devices and a processing unit electrically connected to the light emitting devices and the driving unit is provided. The driving unit is configured to control the light emitting devices, so as to make a first part of the light emitting devices emit a first light. A second part of the light emitting devices are configured to receive a second light which is related to an object, and the processing unit is configured to determine a location of the object touching or approaching the carrier according to the electrical changes generated by the light emitting devices, which sense the second light, of the second part.
