Embodiment Construction

[0039] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040] In the present invention, the sensor is applied in a three-dimensional space, the plane where the light-incident surface of the sensor is located is the xy plane, and the z-axis is perpendicular to the xy plane.

[0041] As an aspect of the present invention, a kind of sensor is provided, such as figure 1 As shown, the sensor includes along the thickness direction of the sensor (ie, figure 1 The grating 110 and the sensor array 120 are arranged in sequence in the up and down direction. The sensor array 120 includes a plurality of photosensitive sensor units 121 , and light can pass through the light-transmitting gaps of the grating 110 to reach the phot...

Abstract

The present application provides a sensor comprising a grating and a sensor array sequentially disposed in a thickness direction of the sensor, wherein the sensor array comprises a plurality of photosensitive sensor units, and light passing through a light transmission gap of the grating reaches the plurality of photosensitive sensor units. The present application further provides a display device comprising the sensor. The sensor may detect three-dimensional coordinates of an object so that the display device can realize three-dimensional touch control.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a sensor and a display device including the sensor. Background technique [0002] In order to facilitate human-computer interaction, touch display devices have appeared. When the operator's finger touches the display surface of the touch display device, the coordinates of the touch point can be determined. However, at present, only the coordinates of the touch point in the two-dimensional plane can be determined, but the coordinates of the touch point in the three-dimensional space cannot be determined, so that other functions such as three-dimensional touch cannot be realized. [0003] Therefore, how to determine the coordinates of the touch point in the three-dimensional space has become an urgent technical problem in this field. Contents of the invention [0004] The object of the present invention is to provide a sensor and a display device including the sensor. Th...
