Abstract

The invention provides a sensing device, which comprises a light emitting module and a sensing layer arranged in a stack; the light emitting module comprises a plurality of light emitting elements which emit near infrared light; the sensing layer includes a plurality of quantum dot thin film transistors; the quantum dot thin film transistor comprises an active layer and a quantum dot covering theactive layer; the light emitted by the plurality of light emitting elements is reflected by the object to be measured and received by the plurality of quantum dot thin film transistors. The inventionalso provides a sensing method. The sensing device of the invention can better sense the suspension operation or biometric identification.

Description

technical field [0001] The present invention relates to a sensing device and a sensing method, in particular to a sensing device for sensing suspension operation or biometric identification. Background technique [0002] As a kind of human-computer interaction device, the device capable of sensing floating operation can detect signals such as the relative position, moving speed and moving direction of the control gesture without the gesture action touching the surface of the device. These detected control gestures can be input as control commands to the electronic product installed with the device, such as turning pages to the left, turning pages to the right, turning pages down, turning pages up, and clicking. Sensing devices that combine hover control functions and display functions, such as e-books, tablet computers, etc., have more and more applications. [0003] Existing control panels with suspension are divided into capacitive type and infrared type. The capacitive ...
