3 Inch Bar Type LCD Display 268×800 IPS
The Perfect Fit for Slim Electronics.
This 3 Inch Bar Type LCD (technically 2.99 inch) is designed for devices that require a long, narrow display interface. With a high density 268 × 800 resolution, it offers crisp, vibrant visuals in a compact 1:3 aspect ratio.
Powered by the industry-standard ST7701S Driver IC, it utilizes an SPI + RGB interface to ensure high-speed data transmission and smooth 60Hz refresh rates. The IPS panel ensures consistent colors from all viewing angles (80/80/80/80), making it ideal for smart pens, handheld instruments, and modern appliance controls.

3 Inch Bar Type LCD: Compact & High Definition
As electronics become smarter and smaller, the demand for non-standard display shapes is exploding. The 3 Inch Bar Type LCD Display (Model: 2.99 inch) is engineered to replace boring LED segments with rich, full-color graphical interfaces in narrow spaces.
Why Choose This 2.99″ Stretched Display?
1. Unique 1:3 Form Factor
With an active area of 24.1mm x 72mm, this screen is perfectly shaped for:
-
Smart Pens: Dictionaries and scanners.
-
Vape/E-Cigarettes: Showing detailed usage stats.
-
Audio Equipment: Digital VU meters and equalizers.
-
Appliance Handles: Washing machines or coffee makers where space is limited horizontally but available vertically.
2. High-Resolution IPS Panel
Don’t let the size fool you. This module packs 268×800 pixels, resulting in a very high PPI (Pixel Per Inch). Text is razor-sharp, and icons are crystal clear. The IPS technology guarantees that the user sees accurate colors even when holding the device at an angle (80/80/80/80 degrees).
3. Proven ST7701S Driver + RGB Interface
The module uses the ST7701S driver IC, which is widely supported in the industry.
-
SPI: Used for sending initialization commands (Init Code) to configure the screen.
-
RGB: Used for high-speed video data transmission, ensuring smooth animations and UI transitions without lag.

Technical FAQ
Q: What is the difference between 3 inch and 2.99 inch?
A: They refer to the exact same product. 2.99 inch is the precise diagonal measurement of the active area, while “3 Inch” is the commonly used industry marketing term.
Q: Can I use this with an MCU like ESP32?
A: Driving 268×800 via RGB requires a lot of RAM and pins. Standard ESP32 (SPI only) is too slow. However, the ESP32-S3 (with RGB interface support) can drive this screen, provided you manage the frame buffer memory correctly. It is best suited for Linux SoCs or higher-end MCUs (STM32H7).
Q: Do you provide the initialization code for ST7701S?
A: Yes. Since this interface requires an SPI init sequence before sending RGB data, we provide the full Init Code and timing parameters to ensure a quick bring-up of your prototype.
