Data sources
- Specifications from the product page of the factory that builds the PJ2804G01-30H50P100 (Shenzhen PengJi Photoelectricity Co., Ltd.).
- Specs transcribed from the spec-chart image on the source page; verify against the datasheet. Surface treatment LR+HC (inner haze 80%). Brightness is the standard-backlight typical value encoded in the PengJi part number (e.g. …P400 = 400 cd/m²), cross-checked against PengJi's product table and datasheets; other backlight levels can be built.
- Confirm final values against the datasheet supplied with samples.
Integration calculations
Figures below are calculated from the PJ2804G01-30H50P100’s 240×400 resolution and MCU (8080 parallel), so you can size the host before requesting samples. Refresh rates are theoretical bus limits; real throughput is lower once command overhead and rendering time are included.
| Pixel density | 167 PPI |
|---|---|
| Native orientation | Portrait (240×400); rotate in the driver for landscape UIs |
| Full frame buffer | 188 KB at RGB565 · 281 KB at RGB888 |
| 8080 parallel refresh (theoretical, 10 MHz WR) | 100+ fps on a 16-bit bus · 52 fps on an 8-bit bus |
At 100 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.
Hosts with a native MCU (8080 parallel) peripheral
LCD_CAM peripheral drives 8/16-bit 8080 (i80) panels with DMA.
- STM32 with FSMC/FMC
The external memory controller maps the panel as memory for fast writes.
Interface support is based on each processor’s published display peripherals, not a bench test of this module. Ask us for tested init code.
