What are the common 5.7-inch industrial LCD screens?
At present, there are many models of 5.7-inch LCD screens on the market, which can be quickly classified based on core performance parameters. The table below summarizes several typical categories and representative models for your convenience in selecting:
Category/Core Features | Representative model | Typical Resolution | Key features/applicable scenarios |
High brightness/high-performance comprehensive model | - | 640×480 | 1000 cd/m ² high brightness, IPS full view angle, -30~80 ° C wide temperature range, MIPI interface. Suitable for harsh environments such as outdoor and in car use |
Standard VGA resolution version | TM057QDH01 (Tianma)、 G057VN01 V2 (AUO) | 640×480 | The brightness is between 400-700 cd/m ², and the interfaces are mostly RGB/Parallel. It is the most widely used industrial standard |
Entry level QVGA resolution model | G057QTN01.4 (AUO)、AA057QD01(Mitsubishi) discontinued production | 320×240 | Low cost, suitable for displaying simple characters, status information, or cost sensitive devices |
Special requirements (high brightness/wide temperature/protection) | KCG057QV1DH-G68 (Kyocera, wide temperature range -30~70 ° C, IP65) | 320×240 | Highlight a certain characteristic, such as ultra-high brightness or extremely wide operating temperature and strong protection |
Interpretation of Key Models
The models in the table above are very representative:
Omnipotent benchmark:
A representative of high-performance integrated models. It integrates multiple high-end features previously discussed: high resolution (640 × 480 brings clarity of approximately 225 PPI), 1000 nits ultra-high brightness (ensuring visibility under strong light), IPS full viewing angle (no color change when viewed from all angles), and ultra wide operating temperature (-30~80 °C). It is equivalent to a "top of the line" solution, which is very suitable for outdoor terminals, special vehicles, high-end industrial controls, and other scenarios that require extremely high reliability.
Classic Selection: Various 640 × 480 (VGA) standard models
Represented by Tianma TM057QDH01, AU G057VN01 V2, etc., these are the mainstream and classic choices in the industrial field. They balance the clarity of around 140 PPI (meeting most interface requirements) with system cost (moderate requirements for main control performance). If your application environment is a regular indoor environment without extreme temperatures or strong light, this type of model is the most reliable and cost-effective choice.
High cost performance basic model: 320 × 240 (QVGA) model
Like the AU G057QTN01.4, this type of model has the lowest cost, but the pixel count is relatively noticeable (PPI of about 70). It is suitable for devices that only need to display simple data, indicator lights, large buttons, or for situations where old devices need to be directly replaced on the screen.
How to choose?
You can make a decision based on the analysis of resolution in the previous question:
Clear information density and viewing distance: Do you need to display complex charts and small text on one screen? How far is the operator from the screen? This determines whether you need VGA or QVGA resolution.
Assessing environmental challenges: Will the equipment be used in sunlight, low-temperature cold storage, or high-temperature workshops? This determines your requirements for brightness and working temperature.
Weighing the total cost of the system: High resolution, high brightness, and wide temperature screens themselves are more expensive, and they also have higher requirements for the main control chip, interface, and power supply. A comprehensive evaluation of the budget is required.
Verify interface and compatibility: Confirm whether the interface of the screen (such as RGB, LVDS, MIPI) is compatible with your motherboard or driver board, which is the key to successful integration.
Overall, for most conventional industrial applications, the standard model with a resolution of 640 × 480 (VGA) is the "sweet spot" with the best balance. If the environment is harsh, add features such as high brightness and wide temperature range.
If you can share the specific application scenarios of the device (such as outdoor handheld terminals, indoor control panels, etc.) and environmental conditions (lighting, temperature), I can help you make more specific recommendations for screening models of 5.7-inch LCD screens.
