Embodiment Construction

[0066] FIG. 5 is a schematic block diagram of a preferred embodiment of a three-stimulus color analyzer of the present invention. The color analyzer has an optical sensing system 400 and a signal processing body 500 . The optical sensing system 400 is aimed at the region MR to be measured on the display panel, so as to capture light from the region MR to be measured and convert it into electrical signals. These electric signals are then transmitted to the signal processing main body 500 for calculation through cables, so as to measure and analyze the optical and color characteristics of the display panel.

[0067] FIG. 5A is an enlarged view of the optical sensing system 400 shown in FIG. 5 . As shown in the figure, the optical sensing system 400 has a light concentrating device 420 , a light homogenizing device 430 and a light receiving device 440 . Wherein, the light converging device 420 is used for converging the specific light beam emitted by the area to be measured on ...

Abstract

The invention relates to a colorful analyzer, comprising an optical sensitive system, facing an object area on a display panel, for picking up the light emitted from the object area. The optical sensing system comprises a spotlight device, a light homogenize device, and a light receiver, wherein the spotlight device can focus special light beam emitted from the object area to a back focus plant. The homogenize device is at the focus plate to disperse and mix the light focused on the focus plate and homogenize the light in a first preset angle to project the light backwards. The light receiver is at the back of the light homogenize device for receiving the light backward projected by the light homogenize device.

Description

technical field [0001] The present invention relates to an optical sensing system and a color analyzer with the optical sensing system, especially an optical sensing system capable of measuring the optical and color characteristics of a flat panel display and an optical sensing system with the optical sensing system Color Analyzer. Background technique [0002] Electromagnetic waves with a wavelength range of 380nm to 780nm can produce vision for the human eye, which is called the visible light band. Within this wavelength range, the human eye can perceive various colors, including violet, indigo, blue, green, yellow, orange, and red. The International Commission on Illumination (CIE) experimented with the human eye in 1931 and formulated a tristimulus value XYZ method to express the color value of each color to quantify the color rendering of various color-related devices, such as digital cameras, monitors, and printers. . [0003] Please refer to FIG. 1 , which is a sch...
