Problems solved by technology

[0003] However, in this method of separately controlling the direct-type backlight of each block, each block needs to be provided with an independent driving circuit. If there are more backlight partitions, there will be more driving circuits; Power devices occupy a large amount of circuit board area due to heat dissipation. At the same time, the space occupied by the direct-lit backlight is also large, which will lead to complex internal structures of the TV, which is not conducive to the miniaturization of the TV back shell and ultra-thin shape. beautiful design

Embodiment 1

[0045] In TVs, monitors and other devices with screen display functions, local dimming technology is usually used to enhance the contrast of displayed images. As the number of backlight partitions increases, so does the number of driving circuits, and these driving circuits are high-power devices, which will occupy a large amount of circuit board area and the internal space of the TV due to heat dissipation.

[0046] This embodiment provides an image display method with enhanced contrast without increasing the space occupied by the terminal equipment. Based on the BD cell stacked screen display technology, a double contrast enhancement processing method is adopted to make the contrast between bright and dark in image display more obvious and improve The image display effect of the terminal device.

[0047] Such as figure 1 As shown, in an implementation manner of this embodiment, the image display method for enhancing contrast includes the following steps:

[0048] Step S100...

Embodiment 2

[0116] Such as Figure 6 As shown, this embodiment provides a terminal, which includes a processor 10, and a memory 20 connected to the processor 10, the memory 20 stores an image display program with enhanced contrast, and the image display with enhanced contrast When the program is executed by the processor 10, it is used to realize the operation of the image display method for enhancing contrast as described in the first embodiment; the details are as described above.

Embodiment 3

[0118] This embodiment provides a storage medium, wherein the storage medium stores a contrast-enhancing image display program, and when the contrast-enhancing image display program is executed by a processor, the contrast-enhancing image display program as described in Embodiment 1 is used to implement The operation of the image display method; specifically as described above.

[0119] In summary, the present invention is based on the BD cell stacked display technology, adopts double contrast enhancement processing, divides the display image into multiple color block arrays on the main liquid crystal display layer, and calculates a single color block and surrounding color blocks one by one Compared with the average brightness value of the entire image, the brightness value of the color block can be enhanced or reduced, making the contrast between light and dark of the displayed image more obvious; moreover, BD cell backlight is also used on the secondary liquid crystal layer ...

Abstract

The invention discloses a contrast-enhanced image display method, a terminal and a storage medium, and the contrast-enhanced image display method comprises the steps: obtaining a display image in a main liquid crystal display layer, and calculating the average brightness value of the display image through a preset algorithm; dividing the display image into a plurality of color lump arrays, selecting a single color lump as a selected color lump, forming the selected color lump array by the selected color lump and surrounding color lumps, and calculating an average brightness value of the selected color lump array; comparing the average brightness value of the selected color block array with the average brightness value of the display image; and adjusting the brightness of a selected color block in the main liquid crystal display layer according to a comparison result, and controlling the auxiliary liquid crystal layer to execute corresponding light flux control. Based on the BD cell stacked screen display technology, a double contrast enhancement processing method is adopted, so that the brightness contrast of image display is more obvious, and the image display effect of the television is improved.

Description

technical field [0001] The invention relates to the field of terminal applications, in particular to an image display method for enhancing contrast, a terminal and a storage medium. Background technique [0002] Local dimming technology has been widely used in TVs. This technology collects the light and dark information of each area in the image data, and separately controls the direct-lit backlight under these areas, so as to enhance the brightness of bright areas and reduce the brightness of dark areas. The brightness of the area can be adjusted to make the contrast of the image screen more vivid. [0003] However, in this method of separately controlling the direct-type backlight of each block, each block needs to be provided with an independent driving circuit. If there are more backlight partitions, there will be more driving circuits; Power devices occupy a large amount of circuit board area due to heat dissipation. At the same time, the space occupied by the direct-l...
