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 1):
An LED display system, comprising:\n an LED display panel; and a driver circuitry that drives the LED display panel, wherein the driver circuitry comprises a scrambled PWM generator, a register, and a memory, wherein the scrambled PWM generator receives a compensated image data, of a grayscale value (X+K), X being a grayscale value of a data from an external image source and K being a compensation value generated by the driver circuitry, wherein the scrambled PWM generator distributes the grayscale value (X+K) into a plurality of segments according the following set of 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.
