Problems solved by technology
[0003] (1) The above method needs to be processed through complex calculations, and complex calculation software / hardware is required to perform this calculation process, so more resources and costs need to be invested;
[0004] (2) If the above method is processed through direct calculation, the color information of one pixel point must be obtained in several pixel points, so too much pattern information will be lost, resulting in the connection between the graphic pixel points on the liquid crystal display If the drop is too large, graphics will be distorted, such as discontinuous lines or discontinuous colors, making the resolution too low
The method of arranging and sampling the image data has the purpose of simplifying the calculation and reducing the resolution; the main disadvantage of its composition is: the image sampling method is too simple, which will cause obvious image distortion
[0006] It can be seen that the above-mentioned existing methods still have many deficiencies, are not really a good design, and need to be improved urgently.

Embodiment Construction
[0023] The display method of the low-resolution dot-matrix display of the present invention can drive the dot-matrix display with smaller pixels by matrixing the image data with more pixels. This method uses the image data processing method to achieve the lowest degree of color image distortion With the purpose of reducing the picture resolution, the method is to make the pixels (pixels) of an original image data matrix M*N, and the pixels (pixels) to be converted to a dot matrix display are P*Q, where P<=M, Q<=N, set the conversion ratio A=M / P (rounded to an integer), select the data in the first row, every 3*A dots are a group T, and take out a red dot from each group T (r value), one green dot (g value), one blue dot (b value), the sampling calculation method is as follows:
[0024] rm, n=(the sum of all red dot R values (the Sth R value*W) in the population Tn) / (A+W-1);
[0025] gm, n=(addition of all green dot G values (the 2Sth G value*W) in the population Tn) / (A+W-...

A display method for a low degree of analytics dot matrix display including that an image information matrix with more picture elements drives a dot matrix display with less picture elements to get the aim of lowest color image distortion and reducing picture degree of analytics image information processing method so as to select gray-level drive IC of small channels to replace the present high value colorful drive IC to reduce price.
Description
technical field [0001] The present invention relates to a display method of a low-resolution dot-matrix display, in particular to a display method for a low-resolution dot-matrix display that achieves the lowest color image distortion and reduces picture resolution through an image data processing method. method. Background technique [0002] The display method of the known liquid crystal display is to store the image data matrix in another matrix corresponding to the pixel of the liquid crystal display after numerical average operation or filter (Filter) processing through complex calculation processing or direct sampling, and then use This processed matrix is used to drive the LCD screen. Only the above display method has the following disadvantages: [0003] (1) The above method needs to be processed through complex calculations, and complex calculation software / hardware is required to perform this calculation process, so more resources and costs need to be invested; ...
