Embodiment 1

[0024] An ordinary LCD monitor and a high-density virtual LED display screen have a resolution of 192×192 and a dot pitch of P1.25, which uses an equivalent 8-bit gray scale. A video processor for realizing virtual reality, the image processing and control system used such as Figure 4 shown.

[0025] Select a picture as the display image, display it on the LCD monitor, and then use MATLAB to process the image according to image 3 The mask is used to process the image, and then each pixel is processed according to the control method of the present invention, that is, the color value of the corresponding point is extracted according to the order of the actual screen. If the actual screen arrangement is as follows figure 2 Arranged in the same way, then extract the value of the red sub-pixel at point (1, 1) of the image as the value of R, and extract the value of the green sub-pixel at point (1, 2) as the value of G, so that it is extracted in order The values ​​of the vario...

Abstract

The invention generally relates to optical modeling and especially relates to an LED virtual display model, for solving the problem of adaptability of a conventional virtual LED display screen modeling method to green, red and blue colors of LED pixel points in the prior art and the problem of gray-scale compromise of a time-division multiplexing technology. The LED virtual display model provided by the invention comprises a modeling method and a control method. In the modeling method, a screen is divided into a plurality of triangles by taking each sub-pixel as a summit, and virtual pixel points are disposed at the center of each triangle. In the control method, a mask layer is created by use of a smooth filter, according to an actual screen sequence, color values of corresponding points are extracted, if the actual screen is arranged in the same way as the modeling method, values of red sub-pixels are extracted at a (1,1) point of an image as the value of R, values of green sub-pixels are extracted at a (1,2) point as the value of G, and thus a new one-dimensional matrix can be re-gained through extracted values of various sub-pixels according to the sequence.

Description

technical field [0001] The present invention relates generally to optical modeling, and more particularly to a LED virtual display model. Background technique [0002] When the human eye observes the scene, it takes a short period of time for the light signal to be transmitted to the brain nerves. After the effect of the light is over, the visual image does not disappear immediately, but lasts for 0.1 second. This property of the human eye is called For "persistence of vision of the eyes". The display principle of the LED display mainly uses the persistence of vision of the human eye: the LED display can be refreshed 60 times within 1 second to form a series of flashing, continuous images in the human eye. Each LED lamp bead is subdivided into two stages of lighting and extinguishing in each refresh process. Since the time interval of a refresh is very short, the refresh process is only light and dark to the human eye. During the display process, the color is formed by adj...
