What are the resolutions of a 5.7-inch LCD screen?
Date:2026-01-28
5.7-inch industrial LCD screen, with multiple resolutions available on the market for selection. The correspondence between these resolutions and their aspect ratios, common names, and main characteristics is shown in the following table:
Resolution (width * height) | Aspect ratio | Common Naming/Standards | Pixel density reference | Main features and typical uses |
320 × 240 | 4:3 | QVGA (Quarter VGA) | About 70 - 141 PPI | Mainstream industrial specifications, simple drive, low cost, commonly used in industrial control, handheld devices, etc |
640 × 480 | 4:3 | VGA | Approximately 141 PPI | The display content is 4 times more than QVGA, with clearer details. Used for industrial interfaces with slightly higher requirements for graphic or text display |
720 × 240 | 3:1 | Special widescreen display | About 60 PPI | Non standard resolution, large width but low height, suitable for specific industries (such as certain printers, barcode scanners, etc.) |
How to choose the appropriate resolution?
When selecting, you can consider the following perspectives:
1. Evaluate display requirements: If the main focus is on displaying text, numbers, and simple icons, QVGA (320 × 240) is sufficient. If you need to display more complex graphics, curves, or multiple lines of dense text, VGA (640 × 480) would be a better choice.
2. Pay attention to aspect ratio: Most industrial screens use the classic 4:3 ratio. And special ratios such as 3:1 are suitable for horizontal information display, but the UI needs to be specially adapted.
3. Check the hardware interface: The higher the resolution, the higher the requirements for the transmission bandwidth and processing capability of the main control chip. When selecting, it is necessary to confirm that your hardware platform (such as MCU) can smoothly drive the screen of this resolution.
4. Pay attention to the protection level and installation method: According to the knowledge mentioned in the previous round, if used in environments with high dust, splashing water, or vibration, priority should be given to models with high protection levels (such as IP65 or above) and support for embedded installation.
If you could tell me what type of device or scenario you plan to use this 5.7-inch screen for (such as machine tool control panels, portable instruments, or other devices), I can provide you with more targeted recommendations for 5.7-inch LCD screen selection.
