Data sources
- Specifications from the product page of the factory that builds the PJ3501I09-34H40P200R (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 PJ3501I09-34H40P200R’s 320×480 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 | 165 PPI |
|---|---|
| Native orientation | Portrait (320×480); rotate in the driver for landscape UIs |
| Full frame buffer | 300 KB at RGB565 · 450 KB at RGB888 |
| 8080 parallel refresh (theoretical, 10 MHz WR) | 65 fps on a 16-bit bus · 33 fps on an 8-bit bus |
At 200 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.

Frequently asked questions
What is the brightness of the PJ3501I09-34H40P200R?
200 cd/m² typical with the standard backlight. At 200 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.
What interface does the PJ3501I09-34H40P200R use?
MCU. Pin definition and timing are in the datasheet, which you can request on this page.
Which processors can drive the PJ3501I09-34H40P200R?
ESP32-S3: 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.
Does the PJ3501I09-34H40P200R have a touch panel?
Yes, a resistive (RTP) touch panel. The non-touch version and other cover-glass options can be built.
What is the MOQ and lead time for the PJ3501I09-34H40P200R?
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.
