Touch-sensing display panel and manufacturing method thereof

摘要

A touch-sensing display panel including a front substrate, scan lines, data lines, pixel structures, photo-sensors, readout devices, a rear substrate and a display medium is provided. The front substrate has an inner surface. The scan lines and the data lines are on the inner surface of the front substrate and intersected to each other. The pixel structures are disposed on the inner surface of the front substrate, and each pixel structure is electrically connected to one of the scan lines and one of the data lines correspondingly. The photo-sensors are disposed on the inner surface of the front substrate. Each readout device is electrically connected to one of the photo-sensor correspondingly. The rear substrate is disposed opposite to the front substrate. The display medium is sealed between the front substrate and the rear substrate.
