TRUE COLOR FLAT PANEL DISPLAY USING AN LED DOT MATRIX AND LED DOT MATRIX DRIVE METHOD AND APPARATUS

摘要

A full color flat panel display module is formed of a matrix of pixels in rowsand columns. Each pixel is formed of respective red,green and blue solid state light emitting diodes that can form any color onthat portion of a CIE curve that falls within a triangle whosesides are formed by a line on the CIE curve between 430 nm and 660 nm, a linebetween 660 nm and a point between 500 and 530 nm, anda line between the 500-530 nm point and 430 nm. The matrix of commonlyconnected LEDs is driven by applying different voltages to thecommonly connected different color LEDs in the matrix of LEDs. A drive circuitmay have commonly connected drivers which multiplexvoltages to an array of commonly connected LEDs such that different voltagesmay be applied to LEDs having different operating voltages.
