Organic light-emitting diodes touch display panel and electronic device using same
An OLED touch display panel capable of detecting and reacting to touches on the display includes a signal sending element emitting ultrasonic signals, a driving layer configured to provide display driving signals, a light-emitting element configured to receive the display driving signals and emit light, and a signal receiving element configured for receiving reflected ultrasonic signals. The light-emitting element includes a plurality of light-emitting units and a plurality of black matrixes. Every two adjacent light-emitting units are separated from each other by one of the black matrixes. The signal receiving element includes a plurality of thin film transistor units arranged in a matrix. Each thin film transistor unit is formed on one of the black matrixes.
