Embodiment Construction

[0030] The technical solution provided by the present invention is to provide multiple image state modes for users to choose, and each image state mode corresponds to a specific screen brightness value. After selecting a certain image state mode, the TV system obtains the corresponding backlight adjustment variable according to the screen brightness value corresponding to the image state mode, and then adjusts the backlight voltage of the TV according to the backlight adjustment variable, so as to realize the adjustment of the screen brightness and the whole machine. Adjustment of the power value.

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. ...

Abstract

The invention discloses an image status adjustment method for a liquid crystal display, which comprises the following steps of a. acquiring backlight adjustment independent variable according to screen brightness value corresponding to an image status mode selected by a user; and b. determining the backlight voltage according to the backlight adjustment independent variable, and adjusting the backlight of the liquid crystal display according to the backlight voltage. The technical proposal of the invention leads the users to select image status modes meeting self needs according to the ambient light and the optimal visual feeling of human eyes, and the television system realizes the adjustment to the screen brightness and overall power consumption according to the selection of the user, thus realizing the harmony of the visual feeling of human eyes, the ambient light and the power consumption of the television when in use.

Description

technical field [0001] The invention belongs to the field of liquid crystal display technology, in particular to a method for adjusting the image state of a liquid crystal display Background technique [0002] The visual experience brought by the brightness of the TV screen to the user is closely related to the magnitude of the ambient light. Experience shows that when the ratio of the two is about 11:1, the human eye feels the most comfortable. According to the architectural lighting design standard, the illuminance requirement for the living room of a residential building is 1001x, and the brightness is about 20-24cd / m 2 , the brightness of the TV screen under this ambient light is set to 260cd / m 2 The effect is good, the brightness of the TV picture is too high or too low, it is not good, the image layering is poor if it is too low, the contrast of the picture is too high, and the color is bright and eye-catching. However, users will feel eye discomfort and fatigue when...
