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 the display method of the display device of the present invention. This method is used to sequentially calculate the sampled pixels of the sampled image to convert the original image containing the pixel matrix M*N into the sampled image containing the pixel matrix P*Q, where M, N, P, Q are all natural numbers, and P≤M , Q≤N, so that the display device with low resolution can display the original image with high resolution. The method includes the following steps:

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

[0039] Combine figure 2 , Is a schematic diagram of one line of pixels of the original image 30 and the sampled image 40 in the display method of the present invention. In this embodiment, the resol...

Abstract

The invention discloses a display device and a display method thereof. According to the method, the gray scale gradients of primary color sub-pixels in multiple sub-pixels of a current original pixel are calculated so that the maximum gray scale gradient value can be selected from the gray scale gradients, then multiple weights corresponding to a current sampling pixel are determined according to the maximum gray scale gradient value, and weighted summation is conducted on the gray scale values of primary color sub-pixels of the current original pixel and an adjacent original pixel by means of the multiple weights, so that the gray scale value of a primary color sub-pixel in a current sub-pixel of the current sampling pixel is obtained. In this way, color aliasing can be effectively eliminated, and a sharp image can be obtained.

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 manufacturing difficulty and reduce the production cost, it is often used to display high-resolution content on low physical resolution devices, such as reducing the content of high-resolution 4K2K data to low-resolution 2K1K and displaying Display on the panel, while ensuring the spatial resolution and detail clarity of the output image. [0003] 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-pixel is sampled separately at each spatial position of the original pixel, and then combined into a new image. This sub-pixel sampling method is called direct sub-pixel down sampling (DSD, DirectSubpixel -basedDown-sampling). However, a...
