0.99 Inch 40x160 Narrow Strip IPS TFT LCD GC9001 4-SPI 10 Pin 400 Nits Pen Display

At 8.6 mm wide and 29.8 mm long, this module is closer to a ribbon than a screen. The 40x160 array on a 6.096 x 24.384 mm area gives a one to four strip, 1.5 mm thick, so it drops into a pen or a toothbrush handle without a bulge. It is a standard transmissive TFT: liquid crystal cells, a transistor and storage capacitor per pixel, two polarisers, a colour filter and a single edge-lit white LED. IPS keeps the crystal rotating in plane, so the narrow picture does not shift colour as the device turns in the hand. The GC9001 controller packs the gate and source drive plus frame memory into a small die, which is what allows a 10 pin 0.7 mm interface to carry a full colour strip at 400 nits.

Toothbrushes show a mode and a timer bar. Smart pens show a battery and a mode icon. Bands show a heart rate beside a time. Pod devices show a level and a puff count. Hearing aid chargers show a charge state per slot. Each narrow face takes only a vertical strip, and needs one or two figures rather than a page.

The mechanical fit is the entire value: an 8.6 mm module width enters a 10 mm handle with room for a lens, which no square panel can do. The strip ratio also lets a fixed set of 40 columns carry an icon column plus four or five characters, so a mode and a number coexist without scrolling. The single LED backlight and 3.3 V rail keep the drive simple in a battery product, and IPS keeps the colour true when a toothbrush or a pen is used at an angle.

The module shows numbers, icons and short labels in 65K colour, takes 4-SPI data, supports windowed updates so a timer digit changes without repainting the strip, and dims through backlight PWM. Because 40x160 is a small frame, even a modest microcontroller with a software SPI port can refresh it, which lowers the host requirement for a low cost device.

Bring-up: apply 3.3 V, release reset, load the GC9001 table for 40x160, set the address window, write the frame, then enable the backlight. The GC9001 is not an ST-compatible part, so an existing ST driver will not work unchanged; confirm the command set and the gamma values, and check the 0.7 mm land pattern before the first board spin.

The long narrow shape is easy to crack: never bend the module along its length and support it near the connection when inserting into a housing. Keep within -20 to +70 C, seal the handle against moisture because these products live in wet environments, and keep the 10 pin solder joint away from flexing stress. A strip that shows a black band after assembly has usually been over-clamped, not failed electrically.

Production ships 5-10 working days after payment. Samples go by express to allow a housing trial, volume by air or sea, with monthly capacity around 100,000 pieces.

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

Modules ship with a protective film, in anti-static trays with foam slots sized to the strip so the ends are not loaded, sealed in a moisture barrier bag and an export carton.

Minimum order is 10 pieces. Units damaged on arrival are replaced after photo verification, the 12 month warranty covers manufacturing defects, and we supply the GC9001 initialization table and a housing support guideline.
