Embodiment Construction

[0023] 3 is a schematic diagram of the first embodiment of the present invention. In this embodiment, the LED display units 10 are arranged in 5 rows and 6 columns, and the long side of each display unit is deflected 45° to the right relative to the reference coordinate axis Y. In the figure, the display unit 11 with 3 rows and 2 columns in the center of the display is the brightest area when the display panel is working, and displays the required image, which is visually displayed as the image of the number 1. Since the long side of each display unit is deflected relative to the reference coordinate axis Y-axis, the diffuse light of the long side of the display unit 11 in the brightest area is shown by the arrow in Figure 3, that is, the deflection relative to the Y-axis is the same as the above-mentioned deflection angle Diffused to both sides obliquely, at this time, the three display units 12 located at the upper left of the area where the display unit 11 is located and the...

Abstract

The LED display plate comprises the matrix of display units, whose long edge is deflected an angle in 30-60 degrees either right or left deflexion related to the reference coordinate axis. The said deflexion makes the light direction of diffusion generate the relevant deflextion angles so as to create the effect of vision fluctuation. Moreover, light-absorbing materials or reflective materials can be coated on the LED display units, making the LED display plate possess various effects of vision fluctuation. The invention generates virtual 3D vision effect without need of changing the display control program.

Description

Technical field [0001] The invention relates to an LED display board, in particular to an LED display board capable of producing virtual stereoscopic visual effects. Background technique [0002] As shown in Figure 1, the existing LED display board is composed of LED units arranged vertically and horizontally to form a display matrix. Each LED unit 10 has two long sides and two short sides, which are respectively parallel to the reference coordinate axes Y-axis and X-axis ( not shown in the figure). When the LED unit emits light, light will diffuse from the above-mentioned long side and short side. For the convenience of explanation, the present invention only uses the light diffusion of the long side for illustration. The direction of diffusion is shown by the horizontal arrow in the figure. Diffusion is relatively weak and is omitted here. [0003] In Figure 1, the luminance of the LED display unit is expressed by the density of spots marked on the display unit. The dens...
