A process for the configuration of optimized contrast voltage values for tft - lcds

摘要

A device (20) for the optimization of a first contrast voltage value (13) of a first: contrast tension and a plurality of second contrast voltage values (15) of second contrast voltages of a tft - lcds (3), wherein the first: contrast tension on a common counter-electrode for all pixel - capacitors of the tft - lcds (3) is placed, wherein the second contrast voltages from a reference voltage pairs, in which a respective voltage on the charge reversal of a pixel on positive and negative image point voltage, wherein the device (20) can be used in order to improve the contrast,– the apparatus (20) a display unit (9), a computing unit (1) and a test pattern generator (5) comprises,– the display unit (9) the tft - lcd (3) and a control circuit (10) comprises,– the control circuit (10) a microcontroller (6) with pulse width modulation, a damper (4), a data memory (7) and a set of voltage sources (8) comprises,– the apparatus (20) has a camera (2), which for the determination of the luminance of the tft - lcds (3) with the use of a..
