Abstract

To solve the problem wherein a sensor region is always scanned in a pressure pattern sensor to increase power consumption in a non-sensing time, and the extension of the service life of each TFT is hindered because the TFT is always driven. A sensor control circuit connected to an H scanner and a V scanner is formed. The non-sensing state of the sensor region is detected to shut off the control circuit, and the H scanner and the V scanner are set to a wait mode. Thereby, power consumption in the non-sensing time can remarkably be reduced, and the deterioration of the TFTs can be restrained.

Description

technical field [0001] The invention relates to a surface pressure distribution sensor and an action control method thereof, in particular to a surface pressure distribution sensor capable of reducing power consumption and an action control method thereof. Background technique [0002] There is a surface pressure distribution sensor using a flexible conductive film and a thin film transistor (Thin Film Transistor) as a detection device for detecting a fine concave-convex pattern like a fingerprint (for example, refer to Patent Document 1). [0003] Figure 10 It shows an example of an active matrix surface pressure distribution sensor for detecting fingerprint patterns. Figure 10 (a) is a plan view, Figure 10 (b) and (c) are Figure 10 (a) C-C sectional view. [0004] The conventional surface pressure distribution sensor 200 includes a substrate 201 of glass or ceramics made of TFTs 204 a forming a plurality of unit detection elements, and a counter electrode thin film 202...
