TAILOR PIXELS TECHNOLOGY CO., LTD. 7 Optical Characteristics Items Viewing angles Symbol Condition Min θT θB Center CR≥10 θL θR - Contrast Ratio Response Time Chromaticity White Uniformity NTSC Luminance Test Conditions: 1. IF= 20mA (one channel), the ambient temperature is 25. 2. The test systems refer to Note 1 and Note 2. Note 1: Definition of optical measurement system. The optical characteristics should be measured in dark room. After 5 minutes operation, the optical properties are measured at the center point of the LCD screen. All input terminals LCD panel must be ground when measuring...

TAILOR PIXELS TECHNOLOGY CO., LTD. Note 2: Definition of viewing angle range and measurement system. Viewing angle is measured at the center point of the LCD by CONOSCOPE (ergo-80). Note 3: Definition of contrast ratio “White state “: The state is that the LCD should drive by Vwhite. “Black state”: The state is that the LCD should drive by Vblack. Vwhite: To be determined Vblack: To be determined. Note 4: Definition of Response time The response time is defined as the LCD optical switching time interval between “White” state and “Black” state. Rise time (TON) is the time between photo detector...

TAILOR PIXELS TECHNOLOGY CO., LTD. Note 5: Definition of color chromaticity (CIE1931). Color coordinates measured at center point of LCD. Note 6: Definition of Luminance Uniformity Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at thecenter of each measuring area. Luminance Uniformity (U) = Lmin/ Lmax L-------Active area length W----- Active area width Fig. 2 Definition of uniformity Lmax: The measured maximum luminance of all measurement position. Lmin: The measured minimum luminance of all measurement position. Note 7: Definition of Luminance:...

TAILOR PIXELS TECHNOLOGY CO., LTD. 9 Precautions For Use of LCD modules 9.1 Handling Precautions 9.1.1The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high place, etc. 9.1.2 If the display panel is damaged and the liquid crystal substance inside it leaks out, be sure not to get any in your mouth, if the substance comes into contact with your skin or clothes, promptly wash it off using soap and water. 9.1.3 Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary. 9.1.4 The polarizer...
