Problems solved by technology

[0004] It should be noted that since the known liquid crystal display device 100 uses two optical sensors 130 and 140, the material cost of the liquid crystal display device 100 is relatively high
In addition, since the second optical sensor 140 in the known liquid crystal display device 100 is fixed in the display area, the second optical sensor 140 will block part of the display area even when it is not in use.

Abstract

The invention discloses an optical sensing module and a display device using the optical sensing module. The optical sensing module is suitable for being assembled onto a frame of the display device. A display module of the display module is provided with a display area, and the frame is arranged around the display area. The optical sensing module includes a casing and an optical sensor. The casing is pivotally connected with the frame, and the optical sensor is arranged in the casing for sensing light irradiating one side of the casing from the outside. When the side of the casing faces to the display area, the optical sensor is suitable for sensing the brightness of the display area; and when the side of the casing does not face to the display area, the optical sensor is suitable for sensing the brightness of the environment.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device with an optical sensing module. Background technique [0002] The image brightness provided by the current liquid crystal display (LCD) is usually set to a fixed value. Therefore, the user may not see clearly when using the LCD device during the day because the picture is too dark. Eyes may get tired easily due to the bright picture. In addition, the brightness and color of the picture provided by the liquid crystal display device may also deviate over time. In order to detect the brightness of ambient light and the brightness and color of the picture provided by the liquid crystal display device, the known art proposes a liquid crystal display device with two optical sensors. Therefore, the brightness and color stability of the picture provided by the liquid crystal display device can be adjusted through the values ​​sensed by these optical sensors. [0003] Pl...
