2-inch TFT LCD screen

  1. Quality priority - choose reliable brands

  The quality of LCD screens is crucial to the quality of products. It is recommended to choose screen glass from reliable brands that have a high reputation in the market and focus on product quality and technological innovation. Some well-known glass brands such as Qunzhuang, Youda, and BOE are all options worth considering.

  2. Resolution and display effect

  The resolution of the screen directly determines the clarity and detail expression of the display effect. Higher resolution can provide a more detailed image display, especially suitable for application scenarios that require displaying a large amount of details. When selecting, it is recommended to choose a screen with a resolution higher than 240x320 to ensure the clarity of the image display.

  3. Touch function - select as needed

  A 2-inch LCD screen usually has two options: touch function and non touch function. If your project or usage requirements require interactive operations, it is recommended to choose a screen with touch function. Touch screens are divided into resistive touch screens and capacitive touch screens. The former is suitable for scenes that require objects such as fingers, pens, or gloves to touch, while the latter is suitable for scenes that require higher sensitivity and multi touch.

  4. Size and Packaging Form

  2-inch LCD screens typically come in two packaging forms: square and rectangular. When selecting, you need to determine the optimal size and packaging form based on the project or usage needs. If you need to display more information, such as text, icons, etc., it is recommended to choose a rectangular screen. If the requirement is relatively simple, such as displaying a single icon or indicator light, a square screen may be more suitable.

  5. Compatibility and Interface Selection

  During the selection process, it is necessary to ensure that the LCD screen is compatible with your device. Understand the interface types of your device, such as SPI, I2C, RGB, LVDS, etc., in order to select the corresponding screen interface. At the same time, it is also necessary to pay attention to the working voltage and current characteristics of the screen to ensure normal driving.

  In summary, selecting a suitable 2-inch LCD screen requires comprehensive consideration of factors such as quality, resolution, touch function, size, compatibility, etc. I hope this article can help you clarify your needs and select the screen that is most suitable for your project or use.
