Abstract

The invention discloses a filter type imaging colorimeter. The filter type imaging colorimeter comprises an optical lens, a reflecting device, a plurality of wavelength selection assemblies with different spectral transmittance and image sensors corresponding to the wavelength selection assemblies, the optical lens focuses light emitted by an object to be measured and then guides the light to the reflection device along an incident light path. The reflecting device is driven by external force to rotate, an included angle between a reflecting surface of the reflecting device and an incident light path is adjusted so as to change the direction of light radiation reflected by the reflecting surface, and light transmitted along the incident light path is sequentially reflected to different wavelength selection assemblies; each wavelength selection assembly filters the received optical radiation so as to transmit an optical signal with a corresponding frequency; each image sensor is arranged on one side, far away from the reflection device, of the wavelength selection assembly so as to receive an optical signal transmitted by the corresponding filter and image; according to the structure, the rotational inertia and the switching angle on the motor are small, the measurement efficiency of the imaging type colorimeter can be improved, and the jamming probability of a rotating system is reduced.

Description

technical field [0001] The present application relates to the technical field of luminance and chromaticity detection, and more specifically, to a filter-type imaging colorimeter. Background technique [0002] At present, the display panel has been widely applied in various scenes of people's life, and has become an indispensable part of daily life. In the production, manufacturing, testing, installation and other processes of display panels, it is a key link to test the quality of the panels before leaving the factory. Among them, the uniformity of chromaticity and brightness produced by the display panel at different positions is an important index for considering the quality of the display panel. Usually there are two ways to measure the chromaticity and brightness of the display screen by point type and imaging type. As the name implies, the point colorimeter has a small measurement area, and the diameter of the measurement area is usually within 30mm. Therefore, it is...
