Panel Identification Method

As the competition intensifies and the technical process level improves, the LCD manufacturers improve the raw material standard. Strengthen internal quality control such as production and inspection, greatly reduce the frequency of bad points. Detection of bad spots is also relatively simple, as long as the LCD screen brightness and contrast to the maximum (display anti-white picture) or to the minimum (display all black picture), you will find how many bright spots and dark spots on the screen. As long as the number of bad points does not exceed A certain standard, it is normal to have multiple bad points, but preferably not below the level A panel standard.

In addition, you can also TEST the other indicators of the LCD with professional TEST software. For example, NOKIA MONITOR TEST is a TEST program that consumers can carry with them on disk. The Software provides 15 options, namely, Geometry and Brightness A) contrast B) High Voltage C) Colors D) Convergence D) Focus Resolution, Moire, Readability, text clarity, Jitter, Sound For LCDS, apart from the inability to test response times, the other major performance parameters are clearly visible, not to mention the downside of consumer concerns. If the display's color purity, contrast and brightness are in question, class B and C panels are no exception.
