Shenzhen Yousee Technology Co., Ltd Product Specification

Shenzhen Yousee Technology Co., Ltd Product Specification YX173FHM-N4F is a color active matrix TFT LCD module using amorphous silicon TFT's (Thin Film Transistors) as an active switching devices. This module has a 17.3inch diagonally measured active area with Full-HD resolutions (1920 horizontal by 1080 vertical pixel array). Each pixel is divided into RED, GREEN, BLUE dots which are arranged in vertical stripe and this module can display 8bit colors and color gamut DCI-P3 100%. The TFT-LCD panel used for this module is a low reflection and higher color type. Therefore, this module is suitable...

Shenzhen Yousee Technology Co., Ltd Product Specification

Shenzhen Yousee Technology Co., Ltd Product Specification 4.0 OPTICAL SPECIFICATION4.1 Overview The test of optical specifications shall be measured in a dark room (ambient luminance < 1 lux and temperature = 25±2°C) with the equipment of luminance meter system (PR730&PR810) and test unit shall be located at an approximate distance 50cm from the LCD surface at a viewing angle of 0 and O equal to 0°. We refer to 00=0 (=03 ) as the 3 o’clock direction (the “right”), 00=90 (= 012 ) as the 12 o’clock direction (“upward”), 00=180 (= 09 ) as the 9 o’clock direction (“left”) and 00=27O(= 06 ) as the...

Shenzhen Yousee Technology Co., Ltd Product Specification 1. Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing angles are determined for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12 o’clock direction with respect to the optical axis which is normal to the LCD surface (see Figure 7). 2. Contrast measurements shall be made at viewing angle of ©= 0 and at the center of the LCD surface. Luminance shall be measured with all pixels in the view field set first to white, then to the dark (black) state . (see Figure 7) Luminance Contrast Ratio...

Shenzhen Yousee Technology Co., Ltd Product Specification TFT-LCD module Optical characteristics measurement setup Figure 7. Measurement Set Up Figure 8. White Luminance and Uniformity Measurement Locations (5 points) Center Luminance of white is defined as luminance values of center 5 points across the LCD surface. Luminance shall be measured with all pixels in the view field set first to white. This measurement shall be taken at the locations shown in Figure 7 for a total of the measurements per display.

Shenzhen Yousee Technology Co., Ltd Product Specification Figure 9. Uniformity Measurement Locations (13 points) The White luminance uniformity on LCD surface is then expressed as : ΔY5 = Minimum Luminance of five points / Maximum Luminance of five points (see Figure 8) , ΔY13 = Minimum Luminance of 13 points /Maximum Luminance of 13 points (see Figure 9). Figure 10. Response Time Testing The electro-optical response time measurements shall be made as shown in Figure 10 by switching the “data” input signal ON and OFF. Tr: The luminance to change from 10% to 90% ,Tf: The luminance to change from...

Shenzhen Yousee Technology Co., Ltd Product Specification Figure 11. Cross Talk Modulation Test Description YA = Initial luminance of measured area (cd/m2) YB = Subsequent luminance of measured area (cd/m2) The location 1/2/3/4 measured will be exactly the same in both patterns. The test background gray is from L64 to L192.Take the largest data as the result. Cross Talk of one area of the LCD surface by another shall be measured by comparing the luminance (YA) of a 25mm diameter area, with all display pixels set to a gray level, to the luminance (YB) of that same area when any adjacent area is...
