Data sources
- Specifications from the product page of the factory that builds the PJ4302B04-36H40P300C (Shenzhen PengJi Photoelectricity Co., Ltd.).
- 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. Touch panel type from the part-number suffix (R = resistive, C = capacitive) and the thicker module outline; confirm the touch controller with the datasheet.
- Confirm final values against the datasheet supplied with samples.
Integration calculations
Figures below are calculated from the PJ4302B04-36H40P300C’s 480×800 resolution and RGB (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 | 217 PPI |
|---|---|
| Native orientation | Portrait (480×800); rotate in the driver for landscape UIs |
| Full frame buffer | 750 KB at RGB565 · 1.10 MB at RGB888 |
| RGB pixel clock for 60 Hz | ≈ 27.6 MHz (incl. ~20% blanking) |
| RGB bus width | 24 data lines (16.7M colors) + PCLK, HSYNC, VSYNC, DE; can be wired as 16-bit RGB565 with the low bits tied |
At 300 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.
Hosts with a native RGB (parallel) peripheral
RGB LCD peripheral (16-bit RGB565) with the 750 KB frame buffer in PSRAM.
- STM32 with LTDC
F429/F7/H7 families drive 16- to 24-bit RGB panels from external SDRAM.
- Raspberry Pi (DPI)
Parallel RGB over the GPIO header via the DPI overlay.
Interface support is based on each processor’s published display peripherals, not a bench test of this module. Ask us for tested init code.

Frequently asked questions
What is the brightness of the PJ4302B04-36H40P300C?
300 cd/m² typical with the standard backlight. At 300 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.
What interface does the PJ4302B04-36H40P300C use?
RGB. Pin definition and timing are in the datasheet, which you can request on this page.
Which processors can drive the PJ4302B04-36H40P300C?
ESP32-S3: RGB LCD peripheral (16-bit RGB565) with the 750 KB frame buffer in PSRAM. STM32 with LTDC: F429/F7/H7 families drive 16- to 24-bit RGB panels from external SDRAM. Raspberry Pi (DPI): Parallel RGB over the GPIO header via the DPI overlay.
Does the PJ4302B04-36H40P300C have a touch panel?
Yes, a capacitive (CTP) touch panel. The non-touch version and other cover-glass options can be built.
What is the MOQ and lead time for the PJ4302B04-36H40P300C?
Samples start from 1 pc. Production MOQ and lead time depend on quantity and any customization (FPC length, backlight, touch), and are agreed per project with our sales team. Send your annual volume and target date for a quote.
