Original 7 "Touch Monitoring Panel Advertising Machine

FeaturesThe Display model is a color active matrix thin film transistor (TFT) liquid crystal display (LCD) that uses amorphous silicon TFT as a switching device. This model is composed of a TFT LCD panel, a driving circuit, and a backlight system. This TFT LCD has a 7 inch diagonally measured active display area with 800*480 pixels.  INSPECTION STANDARDS  1. Purpose  This incoming inspection standard shall be applied to TFT-LCD supplied by MAN ZHENG to its customer.  2. Scope  This inspection standard contains Cosmetic Specifications and Electrical Specifications.  3. Classification of defects  3.1 Major defect. The major defect is a defect that is likely to result in product failure or reduction in Product's intended usage.  3.2 Minor defect.  The minor defect is a defect that has little bearing on the effective use or Operation of the product.  4.Handing Precautions  (1) The display panel is made of glass and polarizer. As glass is fragile, it tends to become or chipped during handling especially on the edges. Please avoid dropping or jarring. Do not subject it to a mechanical shock by dropping it or impact. (2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the substance contacts your skin or clothes, wash it off using soap and water. (3) Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary. Do not touch the display with bare hands. This will stain the display area and degraded insulation between terminals (some cosmetics are determined to the polarizer ). (4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully. Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass, tweezers, etc.). Do not put or attach anything on the display area to avoid leaving marks on. Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizer. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air.  5.Inspection conditions is as follows  5.1 Viewing distance is approximately 35-40 cm 5.2 Viewing angle is normal to the LCD panel as 45° 5.3 Ambient temperature is approximately 25±5ºC 5.4 Ambient humidity is 60±5% RH 5.5 Ambient luminance is from 300-500 Lux. 5.6 Input signal timing should be typical value(3s-5s). 5.7 Mura & Light leakage inspection at ND-Filter 6%.  Mechanical Specifications  ITEMSTANDARD VALUESLCD type7" InchPixel arrangement800(RGB)×480 PixelsOutline Dimension165×100×3.45mmDisplay area153.84(H)×85.63(V) mmPixel Pitch0.0641 ×0.1784 mmDisplay ModeNormally white Viewing Direction6 o'clock -- /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
