Embodiment Construction

[0066] Figure 5 It is a schematic block diagram of a preferred embodiment of the 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] Figure 5A is zoomed in Figure 5 The optical sensing system 400 in. 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 color analyzer, which has an optical sensing system, which is aimed at an area to be tested on a display panel to capture the light emitted by the area to be tested. The optical sensing system includes a light collecting device, a light homogenizing device and a light receiving device. Wherein, the condensing device is used to make the specific light beam emitted from the area to be tested converge on a focusing plane behind it. The light homogenizing device is located on the focal plane, and is used for diffusing and mixing the light converged on the focal plane, and projecting it uniformly backward within a range of a first preset angle. The light receiving device is located behind the light homogenizing device, and is used for receiving the light projected backward by the light homogenizing 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 figure 1 Shown is a sc...
