Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of color display devices, in particular to a color display structure controlled by a motor array. BACKGROUND

[0002] In the existing display technology, most large-screen display devices, such as large screens in shopping malls, use LED, LCD or projector devices as display media. These display devices usually use additive color systems to form large screens.

[0003] Additive color system is a method of creating new colors by adding different colored light sources. The basic principle is that by combining red, green and blue light together at different intensities and proportions, all other colors can be generated. In the additive color system, the maximum intensity of all three colors of light produces white, and no light produces black.

[0004] Subtractive color system is generally based on the mixing of pigments, usually taking cyan, magenta and yellow as the basic colors. When pigments are mixed, the color becomes darker, so when cyan, magenta and yellow pigments are completely mixed, the result is black.

[0005] The traditional RGB additive color system screen such as LED display screen has the following disadvantages when in use:

[0006] 1. Huge power consumption for displaying static pictures;

[0007] 2. Poor visual comfort: due to the active light emission of pixel points, the screen is refreshed multiple times per second, resulting in a flicker effect, so the comfort level is poor when viewed at close range. The present device uses external lighting and has no flicker, so the visual comfort is good.

[0008] The traditional CMY subtractive color system such as printed advertisements has the following disadvantages when in use:

[0009] 1. The picture is completely static and cannot be switched;
