0.91" White OLED Display (Bare Panel, Unsoldered)

Overview

A bare 0.91“ OLED display panel with its own flexible FPC tail, not yet mounted to any driver/breakout PCB — “unsoldered” per the label. This is the raw glass+FPC component that a breakout board (like the assembled 0.96“ I2C OLED module also newly added to this library) would normally be built around. Ships sealed in an opaque anti-static bag, so the panel itself isn’t visible in the supplied photo — everything below is based on the label plus general specs for this well-documented display class, not a direct inspection of the glass.

Key specs

• Size: 0.91“ diagonal (per label)
• Color: white-on-black (per label, “白色显示屏” = white display)
• Typical for this size class (0.91“ OLED with FPC tail), not confirmed for this specific unit since it hasn’t been unsealed:
  • Resolution: 128×32 pixels (the standard 0.91“ OLED resolution — 128×64 is the 0.96“+ size class instead)
  • Driver IC: SSD1306 (near-universal for this display class)
  • Interface: I2C (4-wire: GND, VCC, SCL, SDA) or SPI depending on the specific FPC/board pairing — not confirmed which this bare panel expects until a driver board is chosen/attached
  • Supply voltage: 2.8V–3.3V logic-level typical for bare OLED panels (as opposed to breakout boards with an onboard regulator accepting 5V)

Pinout

Not applicable yet — this is a bare panel with only an FPC tail, no fixed header pinout until it’s soldered to a driver PCB. FPC pin assignment would need to be read from the panel’s own FPC tail markings (not visible while sealed) or a matching datasheet once the panel’s exact model is confirmed.

Wiring / typical usage

This part isn’t usable as-is — it needs to be soldered (or FPC-connected) to a compatible driver board before it can display anything. Given the “unsoldered” labeling, this is likely intended either for a custom PCB design with a matching FPC connector footprint, or for replacing/repairing a panel on an existing OLED breakout. Confirm the FPC pin count and pitch against whatever target board is planned before attempting to solder or connect it — mismatched FPC connectors won’t seat correctly.

Code / libraries

N/A until mounted to a driver board — once wired, standard SSD1306 I2C/SPI libraries (e.g. Adafruit_SSD1306, u8g2) would apply, consistent with the rest of this display class.

Source material

• Bag label (size, color, “unsoldered” status, manufacturer) read directly from the supplied photo — the panel itself is not visible (sealed opaque bag).
• General 0.91“ OLED display class specs (resolution, driver IC, interface): cross-referenced from ProtoSupplies 0.91“ white OLED listing and BuyDisplay’s 0.91“ OLED product line — generic class references, not this specific unsoldered panel.
• Product photo: /inventory/oled-0.91in-unsoldered/product-photo.jpg — the as-supplied sealed bag; the panel itself isn’t visible without opening the anti-static bag, so this photo shows the label only, not the physical part.
• Local files: see /inventory/oled-0.91in-unsoldered/as-supplied.jpeg

Verification

Bag label read directly from photo — high confidence on size, color, and unsoldered status. Everything else (resolution, driver IC, interface, voltage) is UNVERIFIED — inferred from the general 0.91" OLED display class only, since the panel is sealed and unopened. Confirm actual resolution, driver IC, and interface by inspecting the panel/FPC directly once unsealed, before assuming 128x32/SSD1306/I2C.

Notes / gotchas

• Do not assume this is I2C — bare panels in this size class are sold in both I2C and SPI FPC variants, and the label doesn’t specify which.
• Needs a driver/breakout PCB (or a custom design) before it can be used at all — this is a component for a build, not a drop-in module like the assembled 0.96“ OLED module.
• Update this entry with confirmed resolution/interface once the bag is opened and the panel/FPC markings are read directly.
