1.4 Inch ALL O`Clock ST7789V2 Mini LCD Screen Display

The mono LCD display in question is a 1.4-inch TFT transmissive panel with a resolution of 240 (R.G.B) * 240 dots. It utilizes a-SI (amorphous silicon) technology and supports up to 262K colors. The display features a normal black background, providing a visually pleasing and crisp contrast.

With a diagonal length of 1.4 inches, this LCD screen offers a compact yet functional viewing experience. Its viewing direction is designed to cover all angles, allowing users to comfortably view the content displayed on the screen from any direction.

The dot arrangement on the display is arranged in a matrix of 240 by 240 dots, using the RGB (red, green, blue) color model. This configuration enables the screen to render vibrant and accurate colors, enhancing the visual quality of images, graphics, and text.

In terms of physical dimensions, the module measures 27.40*30.23*1.64 mm, making it a small and compact display suitable for integration into various devices. The active area of the screen is 25.20*25.20 mm, providing ample space for content display while maintaining an overall compact form factor.

Each individual pixel on the display has a size of 0.105*0.105 mm, ensuring a high level of detail and clarity in the rendered content. This fine pixel size allows for smooth text rendering and sharp images, contributing to an immersive viewing experience.

To provide illumination, the LCD display employs three white LED backlights. These backlights, consisting of three light-emitting diodes (LEDs), deliver a consistent and uniform distribution of light across the screen. This ensures that the content on the display remains visible and legible, even in low-light environments.

The display utilizes the ST7789V2 driver IC, which serves as the control interface between the display module and the external device. This driver IC enables efficient communication and control of the display, facilitating the smooth operation of the screen and ensuring compatibility with various device architectures.

The interface type employed by this display is 4SPI (Serial Peripheral Interface), a common protocol used for data exchange between microcontrollers and peripheral devices. The 4SPI interface offers fast and reliable data transfer, ensuring quick updates and seamless interaction with the display.

With a luminance rating of 350cd/m2 (typical), this LCD display delivers a bright and vivid output. The high luminance ensures excellent visibility, even in well-lit environments, making it suitable for a wide range of applications.

In terms of temperature tolerance, the operating temperature range of the display spans from -20℃ to 70℃. This allows the screen to function optimally in various climatic conditions and environments. For storage purposes, the display can withstand temperatures ranging from -30℃ to 80℃, ensuring safe and reliable storage over extended periods.

In conclusion, the mono LCD display described above offers a compact and visually appealing solution for displaying content. With its TFT transmissive technology, high resolution, and accurate color rendering, it is well-suited for applications requiring detailed and vibrant visuals. The display's small form factor, wide viewing angles, and compatibility with the ST7789V2 driver IC and 4SPI interface make it an ideal choice for integration into a variety of devices. Additionally, its LED backlighting, high luminance, and wide temperature tolerance contribute to its versatility and reliability in different environments.
