Backlight Accessories

Most LCD panels that we are asked to support have built-in backlight drivers, but whether they are built-in or separate the brightness control method is currently trending to PWM rather than analog. As shown on the LCD Controller Summary all Digital View LCD controllers boards support both analog and PWM backlight adjustment (the exception is the MIPI controller board which is PWM only).

CCFL: As of May 2020 virtually all LCD panels with built-in backlights are using LED, the use of CCFL has effectively stopped (only 9 models were listed as still in production).
