Data sources

  • Specifications from the product page of the factory that builds the PJ4303H04-42H40P400R (Shenzhen PengJi Photoelectricity Co., Ltd.).
  • Specs transcribed from the spec-chart image on the source page; verify against the datasheet. 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 PJ4303H04-42H40P400R’s 800×480 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.

At 400 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 PJ4303H04-42H40P400R?

400 cd/m² typical with the standard backlight. At 400 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.

What interface does the PJ4303H04-42H40P400R use?

RGB. Pin definition and timing are in the datasheet, which you can request on this page.

Which processors can drive the PJ4303H04-42H40P400R?

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 PJ4303H04-42H40P400R 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 PJ4303H04-42H40P400R?

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.
