Embodiment Construction

[0052] As mentioned in the background technology section, in the prior art, the direct type backlight light source uses a large number of LEDs, resulting in increased power consumption of the backlight.

[0053] The inventor found that the reason for the above phenomenon is that in the prior art, in order to improve the advantages of high contrast and high brightness of the display screen with a direct-type backlight, a plurality of micro-LEDs arranged in an array are used as the direct-type backlight, but due to the micro LED The power of the LED backlight is relatively large, and the quantity is large, which results in relatively large power consumption of the direct-lit backlight.

[0054] Based on this, the present invention provides a display method, which is applied to a display device having a direct-type backlight source and a liquid crystal display panel, the direct-type backlight source is divided into a plurality of control blocks, and the display method includes:

Abstract

The invention provides a display method and electronic equipment. The display method is applied to a display device with a direct type backlight source and a liquid crystal display panel, and the direct type backlight source is divided into a plurality of control blocks. The display method comprises the following steps: determining a to-be-displayed image corresponding to to-be-displayed data, and a target control block related to the to-be-displayed image; if the to-be-displayed image and the target control block meet the control condition, adjusting the backlight brightness of the target control block, and adjusting the display data of the pixel units in the display area corresponding to the target control block to be different from the to-be-displayed data. A backlight brightness adjusting technology is combined with gray scale adjustment of a display panel to display an image, so the backlight brightness can be further reduced, and the purpose of saving power consumption of a backlight source is achieved. Due to the fact that the backlight brightness and the gray scale of the display panel are adjusted at the same time, display of more gray scale images can be achieved through different combinations and collocation, and the contrast ratio and the gray scale number of images displayed by the electronic equipment are improved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a display method and electronic equipment. Background technique [0002] At present, most of the LCD screens use LED as the backlight source, and there are two types of LED backlights: side-type and direct-type. High backlight brightness and higher dynamic contrast ratio are gradually being adopted by liquid crystal displays. [0003] However, since a large number of LEDs are used as the light source of the direct-lit backlight, the power consumption of the backlight will increase a lot. Contents of the invention [0004] In view of this, the present invention provides a display method and electronic equipment to solve the problem of high power consumption of backlight light sources in the prior art. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] A display method, applied to a display device with a...
