This comprehensive guide explores the specifications, applications, and considerations for a 2.8 inch 640x480 TFT screen. We'll delve into its technical aspects, common use cases, and help you determine if it's the right display for your project. Learn about its resolution, color capabilities, and potential limitations, ensuring you make an informed decision.
The 2.8 inch 640x480 TFT screen boasts a resolution of 640 pixels horizontally and 480 pixels vertically. This resolution provides a decent level of detail for its size. The pixel density, while not as high as modern smartphones, is sufficient for many applications where sharp, high-resolution images aren't critical. The exact pixel density will vary slightly depending on the manufacturer and the specific screen model. For precise measurements, always refer to the manufacturer's specifications.
Most 2.8 inch 640x480 TFT screens utilize a standard TFT (Thin-Film Transistor) technology. This technology offers a good balance between cost and performance, producing acceptable color reproduction and contrast ratios. However, viewing angles can be a limitation with TFT screens. Color accuracy and brightness might decrease significantly when viewed from extreme angles. The specific color gamut and viewing angle will be detailed in the product specifications.
The backlight type (typically LED) influences the screen's brightness and power consumption. While brightness specifications vary between manufacturers, you can generally expect sufficient brightness for indoor use. Outdoor visibility might be limited in direct sunlight. Specific brightness levels should be found in the technical documentation provided by the screen's manufacturer.
This display size and resolution find application in various devices and systems. Here are a few examples:
When selecting a 2.8 inch 640x480 TFT screen, consider factors such as:
Since specific models vary widely, direct comparison is difficult without specifying brands and models. However, key factors to compare include resolution (though we are focusing on 640x480 here), brightness, contrast ratio, viewing angle, and power consumption. Always consult datasheets from the manufacturers for accurate details.
Feature | Model A (Example) | Model B (Example) |
---|---|---|
Brightness (cd/m2) | 300 | 250 |
Contrast Ratio | 500:1 | 400:1 |
Viewing Angle | 80°/80° | 70°/70° |
