Abstract:
An LED display system has and LED display panel coupled to a driver circuitry. The driver circuitry includes a scrambled PWM generator, a register, and a memory. The scrambled PWM generator receives an image data from an external source and, after certain compensations, is sent to a scramble PWM generator to be distributed according to a new set of rules. Compared with existing technologies, this LED display has a host of benefits, including having a uniform optical energy output at low brightness.

Claim (Index 9):
A method for operating an LED display system, comprising:\n connecting an LED display panel to a driver circuitry comprising a scrambled PWM generator; sending an image data to the driver circuitry, wherein the image data has a value of X; adding a compensation value K to the value of the image data X to form a compensated image data having a grayscale value of (X+K); sending the compensated image data into the scrambled PWM generator, wherein the scrambled PWM generator scrambles the compensated image data into a number of segments according to the following rules: when (X+K) equals or is smaller than G 0 *S 0 , S=ceil((X+K)/G 0 ) and R=mod(X+K, G 0 ), wherein G 0  is a grouping number and S 0  is a preset segment number stored in the driver circuitry, S is the number of output segments, among which S\u22121 segments has a pulse width of G 0  GCLKs and one segment has a pulse width of R; and when (X+K) is larger than G 0 *S 0 , M=floor((X+K)/S 0 ) and L=mod(X+K, S 0 ), wherein L is the number of segments that each receives a pulse width of M+1, while the remaining S 0 \u2212L segments each receives a pulse width of M; and sending the PWM pulses from the scrambled PWM generator to a plurality of power or current sources.
