Evaluation of brightness and color uniformity of LCD displays
By using a two-dimensional color brightness meter for measurement, it is possible to evaluate unevenness and other factors!
Our company conducts evaluations of brightness and color uniformity for emitting surfaces such as OLEDs, titled "Evaluation of Brightness and Color Uniformity of LCD Displays." In brightness measurement (using a two-dimensional luminance meter to measure the display surface), we compare the digital camera images of the LCD display surface with the results obtained from the luminance measurements taken with the two-dimensional luminance meter. While the distribution of uniformity is difficult to discern in the digital camera images, the color scale display of the luminance distribution highlights areas with luminance variation, making it easier to understand. 【Overview of Measurement Equipment】 ■ Measurement Items: Tristimulus Values (X, Y, Z), Chromaticity (x, y) ■ Measurement Range: 0.01 cd/m² to 1,000,000 cd/m² ■ Effective Pixel Count: 1376 × 1024 ■ Emitting Surface Size: Approximately 15 to 115 inches ■ Installation Method/Fixtures: Vertical, horizontal, etc., adaptable to shape *For more details, please refer to the PDF document or feel free to contact us.
