PRODUCTION DATA
Taking 4K micro-LED televation for example, the resolution of the screen is 3840 × 2160, and the screen consists of many modules. The following sections show an example to build a LED display module with 240 × 180 pixels.
The example uses the following values as the system design parameters.
| DESIGN PARAMETER | EXAMPLE VALUE |
|---|---|
| VCC and VR | 2.8 V |
| VG and VB | 3.8 V |
| Maximum current per LED | IRED = 3 mA, IGREEN = 2 mA, IBLUE = 1 mA |
| PWM resolution | 14 bits |
| Frame rate | 120 Hz |
| Refresh rate | 3840 Hz |
| Display module size | 240 × 180 pixels |
| cascaded devices number | 8 |
| devices number per LED display module | 96 |
