Abstract: The disclosure provides a palmprint recognition circuit based on a LTPS technology, a palmprint recognition method and a display screen. The palmprint recognition circuit comprises an optical signal collecting unit, configured to collect an optical signal indicating a palmprint information and convert the collected optical signal into a current signal; a current signal amplifying unit, configured to amplify the converted current signal; and a current signal detecting unit, and configured to detect an intensity of the amplified current signal which indicates a ridge line or a valley line of the palmprint in the palmprint information. Therefore, it can solve the problem of having no palmprint recognition circuit and method for a LTPS-TFT display panel. This can eliminate an influence of a change of parasitic capacitance on the recognition result, wherein the change of parasitic capacitance is caused by a change of a wiring manner in the circuit.

Abstract: The present disclosure proposes a force touch structure, a touch display panel and a display apparatus. The force touch structure comprises a base substrate, a light sensing device located on the base substrate, and a phosphorescence-emitting structure positionally corresponding to the light sensing device. The phosphorescence-emitting structure comprises a first electrode, a second electrode, a phosphorescent layer, and a flexible material layer. The first electrode receives a first voltage signal, the second electrode receives a second voltage signal, and the first electrode and the second electrode are used for forming a capacitor with a constant voltage value under the effects of the first voltage signal and the second voltage signal. The light sensing device is used for receiving phosphorescence emitted by the phosphorescent layer and comparing an intensity of the received phosphorescence with a light intensity detected without force touch to determine the magnitude of force touch.
