Wearable 0.96 Inch 128x64 OLED Display SSD1306 IIC White Panel 2.54 mm Header

A wrist device has two constraints: thickness and current. Organic emission answers both. Each pixel in this 128x64 panel is an organic stack that emits white light when current passes, so no backlight adds a millimetre, and an unlit pixel draws nothing. A liquid crystal panel, by contrast, runs its backlight whether the screen shows text or not. The SSD1306 drives the matrix from a frame buffer on the glass and lifts the panel voltage from the 3.3 V rail with its own charge pump, and the whole module is 2.65 mm thick at 27.3 x 27.8 mm with a 21.744 x 10.864 mm window. Averaged over a day of intermittent use, a band display spends most of its time showing a few dozen lit digits, which is what makes a small cell last.

Fitness bands show a step count and a heart rate. Sleep trackers show a clock and a stage. Medical wrist tags show an ID and a dose time. Wearable scanners show a code and a count. Safety wristbands show a zone and a permit state. Each is glanced at for a second, from a device that must not feel thick.

Thickness is the first advantage: at 2.65 mm the module sits in a band housing without a light guide or reflector, which is what usually forces a wearable to grow. Second, power follows the content, so a face with a few digits costs far less than an always lit backlight. Third, full view keeps the readout legible when the wrist is turned, and -40 to +70 C covers a cold run and a hot dashboard.

The module shows digits, icons, simple charts and scrolling text, takes IIC writes, updates a single row so a clock does not repaint the screen, and dims by pixel current. A host can keep the display off until a button press, write one screen and sleep, which is how a band reaches days of runtime.

Integration: hold the module against the housing with a foam gasket, connect 3.3 V, GND, SCL and SDA with pull ups, then send the SSD1306 initialization, set the multiplex ratio, enable the charge pump, and write a frame. Check the address strap and the bus speed, since a long flex in a band can slow the rise time. Run a burn-in at a mid brightness for an hour and inspect for a stuck row before sealing the housing.

Do not run the panel at maximum brightness for long periods, because organic material ages faster at high current and a permanent dim patch can form. Avoid a static layout left on for days, which leaves a retention ghost. Keep sweat and sunscreen away from the panel edge, do not flex the header joints, and never hot plug the connector. Store below 40 C and away from UV.

Shipments leave 5-10 working days after payment. Sample sets go by express for a housing fit check, series orders by air or sea, and capacity near 100,000 pieces per month supports wearable programs.

T/T, L/C at sight and Western Union are accepted. Samples are prepaid and production runs on a deposit plus balance against documents.

Modules ship in anti-static trays with foam separators, sealed in a moisture barrier bag inside a labelled export carton so a production line can count and issue them quickly.

Minimum order is 10 pieces. Units failing at first power-up are replaced after photo verification, the 12 month warranty covers defects, and our team supports brightness settings and housing gasket design.
