0.96 Inch 80x160 IPS TFT LCD Display Module ST7735 4-SPI 8 Pin 400 Nits Full Colour

This panel works on the same principle as every TFT: a liquid crystal cell per pixel, gated by a thin film transistor, lit by a white LED and read through two polarisers. At 0.96 inch the cell is IPS, both electrodes on one substrate, so the crystal rotates in the plane of the glass; that keeps colour and contrast stable when the eye moves off axis, which matters on a wrist never held square to the face. The 80x160 array on 10.8 x 21.7 mm at 0.135 mm pitch is driven by the long established ST7735 over four wire SPI, and the 8 pin 2.54 mm header exposes GND, VCC, SCL, SDA, RS, RST, CS and BL so a prototype needs no flex.

Fitness bands show a heart rate and a step count. Watches use the strip for a notification. Pocket oximeters show a waveform and a saturation figure. Handheld testers show a menu and a reading. Smart sockets show consumption. Each is a battery device read at 20 to 30 cm, where a tall window fits the product shape.

The first argument is power: a single LED backlight and 20 mA at 3.3 V let a 300 mAh cell run a screen-on cycle for days, which no larger panel in this class can match. The second is the 2.54 mm header, which drops the connector, the flex and a reflow step from a low volume build. The third is the ST7735, whose registers are documented in countless open source libraries, so firmware exists before the hardware arrives. And the IPS cell keeps the small screen readable at an angle, which is the difference between a band that can be glanced at and one that must be turned.

The module displays text, icons, simple graphs and 65K colour images, takes 4-SPI writes, supports partial window updates for a changing digit, controls brightness through the BL pin with a PWM signal, and enters sleep with the display RAM retained. At 80x160 a frame is small enough that even a software SPI port on a modest microcontroller can refresh it without visible tearing.

Initialize in this order: power the 3.3 V rail, hold reset low for at least 10 ms, send the ST7735 initialization sequence including the frame rate and the 80x160 window, then enable the backlight. A common fault is enabling the backlight before the panel is initialized, which shows a white screen the operator reads as a dead unit rather than a firmware bug.

Never exceed 3.6 V, and drive the backlight through a resistor sized for the LED forward voltage rather than directly from the rail. Keep the panel within -20 to +70 C, avoid static discharge when handling the exposed header pins, and do not flex the glass when pressing the module into a bezel. A dim screen usually means a backlight resistor value error, not a panel fault.

Orders ship within 5-10 working days after payment. Prototype quantities go by express, series production by air or sea, and capacity near 100,000 pieces per month covers wearable programs.

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

Modules ship with a protective film, in anti-static trays with foam dividers, sealed in a moisture barrier bag and an export carton marked with model and quantity.

Minimum order is 10 pieces. Transit damage or first power-up failure is replaced after photo verification, the 12 month warranty applies, and we supply the initialization code and pin definition with each shipment.
