Color gamut detection device and method

Abstract

The invention discloses a color gamut detection device. The device includes: a detection body, the detection body has a detection chamber, and the detection body is also provided with a detection port communicating with the detection chamber. The detection body It is a non-transparent material, and the detection chamber is used to place a new red powder LED to be detected; a red optical film, and the red optical film is located at the detection port, so that the new red powder LED to be detected is placed in the detection chamber When it is inside, the light beam of the new red LED to be detected is projected on the red optical film. The invention also discloses a color gamut detection method based on the color gamut detection device. The present invention does not need to pack the new pink LED to be tested into a light bar, nor does it need to put the light bar into the back panel of the device, and cover the optical plate, optical film and liquid crystal screen, so the color gamut can be utilized When the detection device detects the new red powder LED to be detected, the detection efficiency is relatively high.

Description

technical field [0001] The invention relates to the field of color detection, in particular to a color gamut detection device and method. Background technique [0002] As a phosphor material, new red powder is used for new red powder LED. Because of the phosphor characteristics of new red powder itself, the color gamut of LED can be increased to NTSC 94%, so new red powder is widely used in the field of display technology. Among them, the new red LED refers to the new red LED that the blue light chip excites the new red phosphor material to produce green light and red light, and then mixes with the blue light to form white light. [0003] In the related art, a color gamut detection device is provided, in which a new red pink LED is molded into a light bar, then loaded into the back panel of the color gamut detection device, covered with an optical plate, an optical film and a liquid crystal screen, and click Brighten the new red pink LED light bar to play the red, green and...
