  • Method for driving a passive matrix LED display
    Patent number: 11357087
    Abstract: A passive matrix LED display driving scheme based on subframe pulse width modulation (PWM) to increase frame scan rate and further with channel-to-channel compensation is provided. The scheme may comprise: dividing each frame of the display video into T number of subframes; converting a driving signal for a pixel into a N-bit driving data, compensating the driving data with a compensation value; mapping the compensated driving data into the T number of subframes respectively.
    Type: Grant
