Abstract
A display module includes a front panel, a backlight panel, a pressure sensor and a panel frame. The front panel includes an array of display pixels. The backlight panel is disposed under the front panel. The pressure sensor is disposed under the backlight panel, and includes a top electrode layer, an interlayer and a bottom electrode layer. The bottom electrode layer includes plural sub-electrodes. If a first distance between a first sub-electrode and a geometric center of the bottom electrode layer is shorter than a second distance between a second sub-electrode and the geometric center, an area of the second sub-electrode is larger than an area of the first sub-electrode. The panel frame is disposed under the pressure sensor. When an applied pressure is received by the front panel, a magnitude of the applied pressure is sensed by the pressure sensor.
