Embodiment Construction
[0043] In the proximity detection device and the electronic equipment of the embodiment of the present invention, by setting at least two pairs of detection modules, each pair of detection modules includes a transmitting unit and a receiving unit, and the proximity judging device detects the reflection of the pointing object by the receiving unit. After emitting the light emitted by the unit, it can be determined that the pointing object is approaching.
[0044] Such as figure 1 As shown, the proximity detection device of the embodiment of the present invention includes at least two detection modules and a proximity determination module, wherein:
[0045] The at least two detection modules include:
[0046] a first detection module correspondingly provided with a first light emission unit and a first light detection unit; and
[0047] A second detection module correspondingly provided with a second light emitting unit and a second light detection unit;
[0048] The approach...

The present invention provides an approach detection apparatus and an electronic equipment , and the approach detection apparatus comprises: a first detection module which possesses a first light emitting unit and a first light detection unit and is used for obtaining a first light detection result of a direction object; a second detection module which possesses a second light emitting unit and a second light detection unit and is used for obtaining a second light detection result of the direction object; an approach determination module which is connected with the first detection module and the second detection module and is used for determining whether the direction object approaches an area or not according to the first light detection result and the second light detection result; wherein, the distance between the first light emitting unit and the first light detection unit is less than the distance between the first light emitting unit and the second light detection unit; the distance between the second light emitting unit and second light detection unit is less than the distance between the second light emitting unit and the first light detection unit. The present invention realizes the reliable and accurate approach detection.
Description
technical field [0001] The invention relates to the technical field of touch, in particular to a proximity detection device and electronic equipment. Background technique [0002] Touchscreens are increasingly used on personal computers and various handheld devices. [0003] However, the current touch screen responds only when a pointing object (such as a finger or a stylus, etc.) touches the touch screen or the pointing object is very close to the screen, resulting in poor user experience. [0004] If the approach and possible contact point of the pointing object can be detected before the pointing object touches the touch screen, more and better experiences will be provided to the user. Contents of the invention [0005] The purpose of the embodiments of the present invention is to provide a proximity detection device, a touch screen and electronic equipment, which are used in the touch screen, so that the pointing object can be detected at a certain distance from the t...
