Problems solved by technology

[0003] However, if the liquid crystal molecules corresponding to the non-display area are maintained at an opaque angle for a long time, the liquid crystal molecules maintained at a fixed angle will easily age, which will affect the display quality of the display device.

Embodiment Construction

[0021] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0022] Please refer to figure 1 , which is a functional block diagram of a display device according to an embodiment of the present invention. The display device 100 includes a controller 110 , a display panel 120 and a backlight module 130 . The display panel 120 and the backlight module 130 are controlled by the controller 110 . Wherein, the display panel 120 is, for example, a liquid crystal display panel.

[0023] Please refer to figure 2 , which shows figure 1 An exploded view of the display unit. The display panel 120 has a display surface 120d, and the display surface 120d defines a non-display area 120d1 and a display area 120d2. When the display device 100 is in a partial image display state, a part of the display surface 120d does not display an image...

Abstract

The invention relates to a control method for a display device and a display device adopting the same. The display device comprises a controller, a display panel and a backlight module, wherein, the display surface of the display panel comprises a nondisplay area; the backlight module selectively opens or closes the backlight brightness of the nondisplay area; when the backlight module closes thebacklight brightness and the time of the display panel outputting dynamic picture signal exceeds a first time interval, the display panel outputs dark picture to the nondisplay area, then the backlight module opens the backlight brightness; before the backlight module opens the backlight brightness, the display panel outputs the dark picture to the nondisplay area at first, and after the backlight module opens the backlight brightness, the display panel outputs dynamic picture signal to the nondisplay area; and when the time of the backlight module opening the backlight brightness exceeds a second time interval, the backlight module closes backlight brightness and the display panel outputs dynamic picture signal to the nondisplay area. The invention can avoid rapid ageing of liquid crystal molecules and the backlight module.

Description

technical field [0001] The present invention relates to a control method for a display device and a display device using the same, and in particular to a control method for a display screen capable of controlling the brightness of a local backlight and a display device using the same. Background technique [0002] When the display device is in a partial picture display state, the non-display area of ​​the display surface usually does not display any color picture, for example, the non-display area usually displays a black picture, so that the liquid crystal molecules corresponding to the non-display area (when the display device is a liquid crystal display device) ) maintained at an opaque angle. [0003] However, if the liquid crystal molecules corresponding to the non-display area are maintained at an opaque angle for a long time, the liquid crystal molecules maintained at a fixed angle are prone to aging, which will affect the display quality of the display device. Cont...
