Problems solved by technology

[0005] However, the production cycle of LED light strips in the prior art is relatively long, usually 1 to 2 weeks, and because different LED light strips need to be selected for re-testing, this can easily lead to an extension of the entire liquid crystal display development and production cycle; therefore, If the LED light source can be used for white balance test, and then help to select the chromaticity and brightness level of the LED light bar required by the display module, the R&D and production cycle of the LCD can be shortened to a certain extent

Abstract

The invention relates to the technical field of display, in particular to a light source luminescence characteristic detection device which comprises a positioning mechanism and a detector, wherein the positioning mechanism is used for fixing a light source, and the detector is used for acquiring parameters of emergent light of the light source. By the aid of the positioning mechanism and the detector, luminescence characteristics of the light source can be detected, the chrominance and the brightness level of the light source needed by a display module can be selected, and the research, development and production cycle of a liquid crystal display is shortened.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a device for detecting light emission characteristics of a light source. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is widely used in televisions, mobile phones, monitors and other electronic products due to its advantages of stable picture, vivid image, radiation elimination, space saving and energy saving. , has occupied a dominant position in the flat panel display field. [0003] Since the liquid crystal display panel itself does not emit light, a backlight module is required to provide a light source for it. At present, the main components of the backlight module include light strips, reflectors, light guide plates, optical film materials, plastic frames, and backplanes; because LED (Light-Emitting Diode, light-emitting diode) light strips have small size, low operating voltage, Due to the advantages of small working current, unifo...
