Embodiment Construction

[0036] The present invention will be described in detail below with reference to the drawings and embodiments.

[0037] refer to figure 1 , is a flowchart of an embodiment of a display method of a display device according to the present invention. This method is used to sequentially calculate the sampling pixels of the sampled image to convert the original image containing the pixel matrix M*N into a sampled image containing the pixel matrix P*Q, where M, N, P, and Q are all natural numbers, and P≤M , Q≤N, thus, the display device with low resolution can display the original image with high resolution. The method comprises the steps of:

[0038] Step S101: Obtain the grayscale values ​​of the current original pixel of the original image and multiple sub-pixels of its adjacent original pixels.

[0039] to combine figure 2 , is a schematic diagram of a row of pixels of the original image 30 and the sampled image 40 in the display method of the present invention. In this em...

Abstract

The present invention discloses a display device and display method thereof. The method comprises: computing grayscale gradients of primary color subpixels in multiple subpixels of a current original pixel, so as to obtain a maximal grayscale gradient value from the grayscale gradients; then determining, according to the maximal grayscale gradient value, multiple weighting factors corresponding to a current render pixel; and using the multiple weighting factors to compute a weighted sum of grayscale values of respective primary color subpixels of the original pixel and neighboring original pixels thereof, so as to obtain a grayscale value of a primary color subpixel in current subpixels of the current render pixel. In this way, the present invention can effectively eliminate color aliasing and acquire a clear image.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a display method thereof. Background technique [0002] In the field of flat panel display technology, in order to reduce the difficulty of process manufacturing and reduce production costs, it is often used to display high-resolution content on devices with low physical resolution, such as reducing the content of high-resolution 4K2K data to low-resolution 2K1K and displaying It is displayed on the panel, and at the same time, it is necessary to ensure the spatial resolution and detail clarity of the output image. [0003] Sub-pixel sampling (Sub-pixel Rendering) and sub-pixel multiplexing can improve the spatial resolution of the display. In the current sub-pixel sampling method, the RGBW sub-pixels are respectively sampled at each spatial position of the original pixel, and then combined into a new image. This sub-pixel sampling method is called ...
