1.65 Inch 142x428 IPS TFT LCD Panel NV3007 4-SPI 13 Pin 350 Nits Slim Bar Display Module

This panel is built around an extreme aspect ratio: 142x428 on a 13.16 x 39.68 mm active area, roughly one to three, the shape of a wrist band rather than a phone. It is a transmissive TFT, each pixel a liquid crystal cell switched by its own transistor, lit by three white LEDs and read through crossed polarisers, with a colour filter giving red, green and blue subpixels. IPS puts both electrodes on one substrate so the crystal rotates in plane and colour holds across a full angle. The NV3007 controller handles the gate and source drive, the frame memory and the SPI interface, and it is what makes a 428 line panel practical on a four wire bus. At 1.19 g and a 0.7 mm pitch 13 pin solder connection, the module is light enough to ride on a wrist without a counterweight.

Sports watches show pace, heart rate and a lap list on one narrow face. Bands stack notifications. Wearable patches show a trend and a timestamp. Cycling computers show gradient, cadence and elapsed time. Each housing is about 15 mm wide, where the strip supports six to eight text rows instead of two.

The ratio is the product: a one to three window turns a watch face into a list, so pace, heart rate and split times coexist without paging. Weight is the second factor at 1.19 g, which keeps the module from dominating the balance of a light wearable. The 3.3 V single rail and the SPI bus keep the host simple, and the NV3007's internal RAM means the host can sleep while the panel holds a frame. IPS keeps the display readable when the wrist is turned, which on a band is most of the time.

The module shows text rows, icons, progress bars and 65K colour graphics, accepts 4-SPI writes, supports windowed updates so a single changing figure does not repaint the strip, and dims through backlight PWM. Vertical scroll in the controller lets a host move a list without redrawing it, which suits a lap or notification feed.

Start-up: apply 3.3 V, reset, load the NV3007 initialization table for 142x428, set the address window, write the frame, then switch on the backlight. Because NV3007 is not an ST7789 part, an existing ST driver will not work as is; confirm the command set and the gamma table before the first enclosure build, and check the 0.7 mm solder land pattern against the drawing.

The 13 pin solder connection is the weak point in a wearable: specify a strain relief and avoid repeated flexing of that joint, otherwise a wrist movement becomes an intermittent column fault. Keep within -20 to +70 C, do not press on the glass when fitting a cover, and keep moisture out of the bond area. Exceeding 3.6 V on the logic rail will damage the controller before the panel shows any symptom.

Production ships in 5-10 working days after payment. Samples go by express, volume by air or sea freight, and monthly capacity near 100,000 pieces supports wearable production runs.

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

Each panel ships with a protective film, in anti-static trays with foam separators, sealed in a moisture barrier bag and a rigid export carton marked with model and quantity.

Minimum order is 10 pieces. Units failing on arrival are replaced after photo verification, the 12 month warranty covers manufacturing defects, and our engineers supply the NV3007 initialization sequence and land pattern review.
