Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0023] Please see figure 1 The illustrated electronic device 100 of the present application is disposed on a side of the light-transmittable display panel 30 away from the light-emitting surface 31 . The display panel 30 generally includes a first polarizer 41 , and the first polarizer 41 can be used to eliminate light reflection of ambient light in the display panel 30 and perform polarization filtering on incident ambient light. The display panel 30 include...

Abstract

The invention relates to a photosensitive module which is arranged on one side, far away from a light-emitting surface, of a light-transmitting display panel. The light-emitting surface of the displaypanel comprises a first polaroid, and the photosensitive module comprises a first optical sensor, a second optical sensor and a second polaroid. The optical axis of the first polaroid is perpendicular to the optical axis of the second polaroid, and the second polaroid is arranged between the second optical sensor and the display panel. Therefore, the first light sensor can receive ambient light and light generated by the display panel, and the second light sensor can only receive light generated by the display panel. The current ambient light intensity can be obtained by calculating the lightdifference received by the first light sensor and the second light sensor. The invention further relates to a display device and electronic equipment equipped with the photosensitive module, and since a hole does not need to be formed in the display panel to monitor ambient light, a full screen can be realized, and the use experience of a user is improved.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a photosensitive module that avoids openings on a display surface, and a display device and electronic equipment using the photosensitive module. Background technique [0002] Current electronic equipment is usually equipped with an ambient light sensor and a proximity sensor. The ambient light sensor is mostly used to monitor the intensity of ambient light to automatically adjust the display brightness of the screen. The proximity sensor is mostly used to automatically turn off the screen when the user answers the phone. These sensors are usually placed under the screen, and usually need to open holes in the screen to receive external light. In the process of the development of electronic devices towards a full screen, the traditional way of using sensors can no longer meet the needs of users. How to accurately detect ambient light without opening holes has become ...
