Product Overview
The FZ784-4001280 is an industrial-grade 7.84 inch Thin-Film-Transistor Liquid Crystal Display module in an ultra-wide bar (strip) form factor with a 400x1280 portrait resolution. The active area measures 59.4 (H) x 190.08 (V) mm while the LCM outline is only 65.32 (H) x 201.30 (V) x 3.35 (D) mm, giving the panel a slim, elongated appearance that is purpose-built for shelf-edge digital signage, smart-appliance status strips, and industrial control panels where vertical / horizontal mount is required. The a-Si TFT panel uses an in-plane-switching (IPS) cell with ALL viewing direction, so the image stays color-consistent from any angle. Driven by the Novatek NV3051F controller over a 4-lane MIPI-DSI interface, the module delivers 16.7M true-color output at low EMI and high frame rate, which makes it suitable for video-driven HMI scenarios. The backlight uses 12 white LEDs in parallel to provide uniform luminance across the long axis. Engineered and manufactured by Shenzhen FuZheng Photoelectric Co., Ltd, every FZ784-4001280 unit ships with stable production quality, competitive factory pricing, and full OEM/ODM customization (FPC length, pin-out, brightness tuning).

Mechanical Drawing & Notes
The FZ784-4001280 uses an a-Si TFT active-matrix structure with an RGB-stripe pixel arrangement. The LCM outline is 65.32 (H) x 201.30 (V) x 3.35 (D) mm and the active area is 59.4 (H) x 190.08 (V) mm, leaving a 2.96 mm symmetric bezel on the short axis and 5.61 mm symmetric bezel on the long axis. The polarizer is anti-glare treated and the backlight uses 12 white LEDs distributed along the long axis to provide uniform luminance. The FPC is plug-in 40-pin (插接40pin) on a 0.5 mm-pitch connector for easy assembly. Two M3 mounting bosses are reserved on the metal frame for chassis fixation.

FAQ — Frequently Asked Questions
Q1: What makes the FZ784-4001280 a "bar display" and what is it typically used for?
A bar display is a TFT-LCD with an elongated aspect ratio (in this case ~1:3.2 portrait, 400x1280 pixels). It is designed to be installed in narrow spaces where a square or rectangular panel would not fit, such as retail shelf edges, smart appliance doors, elevator indicators, and industrial control strips. The slim 65.32 x 201.30 mm outline makes it ideal for vertical or horizontal mount behind a long, narrow cut-out.
Q2: What is the controller / driver IC and what interface does it use?
The module is built around the Novatek NV3051F controller and uses a MIPI-DSI 4-lane interface (D0P/N, D1P/N, D2P/N, D3P/N plus CLKP/N). This high-bandwidth serial interface delivers smooth 16.7M-color video and is supported by most modern application processors including Rockchip, Allwinner, NXP i.MX and MediaTek.
Q3: What is the recommended backlight driving condition?
The backlight uses 12 white LEDs in parallel. Pin 35 / 36 (LEDA) is the anode and pin 28 / 29 (LEDK) is the cathode. We recommend a constant-current LED driver with a total forward current of 60-120 mA (5-10 mA per LED string × 12). Boost driver ICs such as the MP3302, TPS61165 or similar are commonly used.
Q4: Can the panel be mounted in landscape orientation?
Yes. Although the native resolution is 400x1280 portrait, the IPS cell supports image rotation in the controller. By changing the display orientation register (MADCTL) in the NV3051F, the panel can be driven in 1280x400 landscape mode without any mechanical change. We can also re-flip the polarizer / FPC pinout for OEM/ODM orders to optimize the optical performance in landscape installations.
Q5: What is the operating temperature range? Is it suitable for outdoor use?
The standard operating temperature is -20 ~ +70 °C and storage temperature is -30 ~ +80 °C, which covers most indoor commercial and industrial scenarios. For outdoor or direct-sunlight installations we recommend a customized high-brightness variant (>800 cd/m² backlight) and a UV-resistant polarizer. Contact our sales team for outdoor-grade customization.
Q6: Do you provide initialization code, datasheet, and reference schematics?
Yes. With every sample order we provide the full datasheet (PDF), the NV3051F initialization code, recommended reference schematic, and the MIPI-DSI porting guide for popular application processors. Our engineering team can assist with bring-up questions during your evaluation.
Q7: What is the lead time and minimum order quantity (MOQ)?
Standard FZ784-4001280 variants are kept in stock for sample orders. Mass-production MOQ is typically 500 ~ 1,000 pcs depending on configuration. Lead time is 10 ~ 15 working days for stocked variants and 20 ~ 30 working days for custom variants. Contact our sales team for an exact quote.
