Display module with pressure sensor
First Claim
1. A display module, comprising:
- a front panel comprising an array of display pixels;
a backlight panel disposed under the front panel;
a pressure sensor disposed under the backlight panel and attached on the backlight panel, and the pressure sensor comprising a top electrode layer, an interlayer and a bottom electrode layer, wherein the bottom electrode layer comprises plural sub-electrodes, wherein areas of the sub-electrodes are determined according to distances between the sub-electrodes to a geometric center of the bottom electrode layer; and
the sub-electrodes comprise a first sub-electrode, a second sub-electrode and a third sub-electrode, wherein if a first area of the first sub-electrode is smaller than a second area of the second sub-electrode and the second area of the second sub-electrode is smaller than a third area of the third sub-electrode, a first distance between the first sub-electrode and the geometric center is shorter than a second distance between the second sub-electrode and the geometric center, and the second distance between the second sub-electrode and the geometric center is shorter than a third distance between the third sub-electrode and the geometric center; and
a panel frame disposed under the pressure sensor,wherein when an applied pressure is received by the front panel, a magnitude of the applied pressure is sensed by the pressure sensor.

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.
