Technical overview — what these specifications mean for your design
The table above lists the published format of this rectangular display. The notes below explain how each value affects an actual enclosure, firmware and end-product decision, so you can judge fit before requesting a quotation.
Panel, resolution and form factor
The 3.98 inch rectangular panel runs a native 320x480 pixel format. Because the format is built to order, we match the resolution to the host board you already drive — no frame-buffer rework, no scaling artifacts on a non-standard aspect ratio.
Outline and active area
Outline Confirmed per project with an active area of Confirmed per project (all mm). The difference between the two is the bezel, driver area and connector allowance your mechanical drawing must reserve — send us your cut-out drawing and we confirm the fit before tooling.
Brightness and viewing conditions
Specified at 300 cd/m². Indoor builds run standard backlights; semi-outdoor and sunlight-readable builds add a high-brightness backlight, cover glass and optional optical bonding for contrast in direct light.
Interface, glass and touch
Electrical interface: RGB/SPI/MCU. Glass: standard tft glass; cover glass optional. Touch: optional — none / resistive / capacitive (ctp). An HDMI driver board is available as an add-on — hdmi converter driver board available as add-on — so the module connects straight to HDMI sources without a custom carrier board.
How ordering works
This size ships under the Special Shape Displays build-to-order programme — it is separate from the 193-model standard catalogue. Send size, resolution and outline; you get a datasheet, feasibility review and quotation within one business day. Interface, brightness, touch and outline can all be adjusted per project.

Frequently asked questions about the 3.98 inch Rectangular display
What resolution is the 3.98 inch Rectangular display available in?
The 3.98 inch Rectangular format is built on 320x480. We match the native pixel format so your host controller does not need to change — tell us the resolution and interface your board already drives and we confirm the match on the datasheet.
What are the active area and outline of the 3.98 inch Rectangular display?
The published active area for the 3.98 inch build is Confirmed per project. Send us the space available in your enclosure and we confirm the mechanical fit, including any FPC routing and bezel allowance.
What interface does the 3.98 inch Rectangular display use?
RGB/SPI/MCU. We confirm the connector, signal timing and backlight driving as part of the released datasheet.
How bright is the 3.98 inch Rectangular display?
Specified at 300 cd/m². For sunlight-readable or outdoor positions, a high-brightness backlight with cover glass and optical bonding can be reviewed against your brightness and viewing-angle requirement.
What glass type and touch option does the 3.98 inch Rectangular display support?
Standard TFT glass; touch is optional — none / resistive / capacitive (CTP), with or without cover glass. Optical bonding is available for outdoor and high-contrast builds.
Can I get an HDMI driver board for the 3.98 inch Rectangular display?
Yes. An HDMI to MIPI/LVDS converter driver board is available as an add-on so the module plugs into HDMI sources such as media players, SBCs and industrial PCs. We confirm the board match per project.
Is the 3.98 inch Rectangular display in stock or built to order?
The 3.98 inch Rectangular display is built to order. Send us the size, resolution and outline and we return a datasheet, feasibility review and quotation.
