Problems solved by technology

However, during operation, the existing light sensor often cannot accurately sense external light due to external interference
For example, when the user accidentally covers the light sensor with his hands or other objects, and the light in the actual environment has not changed much at this time, the light sensor will mistakenly think that the ambient brightness is low at this time, and then pass the The control unit automatically turns down the brightness of the display, causing inconvenience to the user

Embodiment Construction

[0012] see figure 1 The display device 100 provided by the preferred embodiment of the present invention can be applied to any electronic product with a display function, such as a computer, a tablet computer or a mobile phone. The display device 100 includes a display unit 10 , a light sensing unit 20 , a control unit 30 and a storage unit 40 .

[0013] Please also refer to figure 2 A receiving hole 11 is defined in the middle of the top of the display unit 10 for receiving the light sensing unit 20 . The apex angle α of the vertical section of the accommodating hole 11 is an obtuse angle, such as 120 degrees.

[0014] The light sensing unit 20 is disposed in the accommodating hole 11 for periodically sensing the brightness value of the surrounding environment of the display device 100 . In this embodiment, since the apex angle α of the vertical section of the accommodating hole 11 is an obtuse angle, the light sensing unit 20 can collect the light of the surrounding envi...

Abstract

The invention provides a display device which comprises a display unit, a photoinduction unit and a control unit. An accommodating hole is formed in the middle position of the top of the display unit. The vertex angle of the vertical cross-section of the accommodating hole is an obtuse angle. The photoinduction unit is arranged in the accommodating hole and used for periodically inducting the brightness of the environment surrounding the display device. The control unit is electrically connected with the photoinduction unit and used for obtaining the ambient brightness value inducted by the photoinduction unit so as to determine a current brightness level corresponding to the current ambient brightness value and judge whether the current brightness level changes relative to a historical brightness level; if the current brightness level changes, the display brightness of the display unit is adjusted according to the current brightness level. The display device can be effectively prevented from being touched by a user by mistake, and can collect the light in the environment surrounding the display device to the maximum extent so as to improve the sensing accuracy.

Description

technical field [0001] The invention relates to a display device, in particular to a display device capable of automatically adjusting its own brightness. Background technique [0002] Currently, most displays are equipped with light sensors to obtain ambient brightness and automatically adjust display brightness according to the ambient brightness. For example, when the light sensor senses that the ambient light is bright, the control unit inside the display will increase the brightness of the display, so that the human eyes can see the content displayed on the display more clearly. Conversely, when the light sensor detects that the ambient light is relatively dark, the control unit inside the display will lower the brightness of the display to avoid glare to human eyes caused by the high brightness of the display. However, during operation, the existing light sensor is often unable to accurately sense external light due to external interference. For example, when the use...
