Abstract

The invention provides an optical distance sensing device and electronic equipment. The light distance sensing device is applied to the electronic equipment and comprises a cover plate and a light distance sensor assembly; the cover plate comprises a light inlet side and a light outlet side which are opposite to each other, and the light distance sensor assembly is arranged on the light outlet side of the cover plate; an arc-shaped groove is formed in the surface of the light emitting side of the cover plate, and the light sensing face of the light distance sensor assembly faces the arc-shaped groove. And light incident from the light incident side of the cover plate penetrates through the arc-shaped groove and irradiates the light sensing surface. The light distance sensing device provided by the invention meets the large-angle range requirement of the light receiving of the light distance sensor, the performance of the light distance sensing device can be improved, the structure is simple, the extra space of electronic equipment is not occupied, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to an optical distance sensing device and electronic equipment. Background technique [0002] The light sensor and the distance sensor can be integrated into a light distance sensor. Among them, the light sensor can adjust the screen brightness of the mobile terminal according to the brightness of the external environment; the distance sensor detects the distance between the shield and the screen through infrared rays or other methods, so as to facilitate the user to control the mobile terminal. [0003] In order to improve the accuracy of detection, the optical distance sensor needs to detect light with a wider angle, that is, the light that finally enters the photosensitive surface of the optical distance sensor has a large angle range. figure 1 It is a structural schematic diagram of increasing the detection angle range of the optical distance sensor in the related art....
