Electronic color card based on multicolor light source color matching

Abstract

The invention relates to an electronic color card based on multi-color light source color matching, which is a handheld device, a PC is connected to a control board through a USB interface, and a serial communication circuit is connected through a serial communication interface on the control board to send the RGB value of a target light source into the control panel. The main control chip in the board, or the RGB value set by the control panel is sent to the main control chip in the control board, and the set value is displayed on the display screen. After the main control chip processes the data, it outputs the duty required for the three primary colors of the target light source The ratios D1, D2, and D3 are sent to the driver chip, and the driver chip drives the three-color light source to work, and the light shines through the light source mirror as an electronic color card after color matching. Using the LED light group as the color matching light source of the electronic color card, the light source of the corresponding color is output by adjusting the mixing duty cycle of the primary color light source, and has the advantages of small size, low power consumption, and easy portability, which solves the problem of easy wear and tear of the traditional color card. To solve the problem of fading, the colors are richer and more precise, which greatly expands the color range of traditional color cards.

Description

technical field [0001] The invention relates to an electronic color card, in particular to an electronic color card based on multi-color light source color matching. Background technique [0002] A color card is a reflection of colors that exist in nature on certain materials (such as paper, fabrics, plastics, etc.). It is used for color selection, comparison, and communication. It is a tool for achieving uniform standards within a certain range of colors. Color cards are currently widely used in fashion accessories, home furnishings, cosmetics, industrial products, paints, interior decoration and other industries. The use of color cards ensures correct color communication and quality assurance at every stage of product development. The production of traditional color cards has high requirements on the color plates, and the instability of the quality of the color plates will affect the accuracy of the color cards, resulting in errors between the produced color cards and the...
