Problems solved by technology

However, due to factors such as process fluctuations in the preparation of the array substrate, the bridge pressure sensor is unbalanced when the external pressure is not sensed, resulting in the touch display panel being unable to accurately detect the magnitude of the touch pressure on it.

Abstract

The invention discloses an array substrate and a touch display panel. The array substrate comprises a display area, a non-display area surrounding the display area, a plurality of semiconductor pressure sensors located in the non-display area, a voltage applying circuit for applying voltages on the semiconductor pressure sensors, a voltage detecting circuit for obtaining strain voltages of the semiconductor pressure sensors, a plurality of resistance correcting circuits, wherein each semiconductor pressure sensor comprises a plurality of semiconductor resistors for sensing external pressure, at least one semiconductor resistor in each semiconductor pressure sensor corresponds to the resistance correcting circuit, the resistance correcting circuit is used for correcting the specific resistance of the corresponding semiconductor resistors so that the semiconductor resistors in all the semiconductor pressure sensors in the array substrate are balanced when not sensing external pressure, the corresponding strain voltages are preset initial values, and the magnitude of touch pressure can be accurately detected according to the strain voltages through the touch display panel.

Description

technical field [0001] The present application generally relates to the field of display technology, and in particular to an array substrate and a touch display panel including the array substrate. Background technique [0002] At present, more and more electronic devices are equipped with touch display panels, for example, information inquiry machines in halls of public places, mobile phones and computers used by users in daily life. When a user touches the touch display panel with eg a finger, the touch display panel sends a signal to the device. There are many touch display panels in various devices that not only need to detect the touch position, but also need to detect the touch pressure. The touch display panel can usually use a pressure sensor to detect the magnitude of the touch pressure. [0003] The pressure sensor used in the touch display panel in the prior art is usually a bridge type pressure sensor. When the bridge pressure sensor does not sense the external...
