With the rapid development of liquid crystal display technology, TFT LCD display has become the mainstream choice in many industries. Whether in consumer electronics, industrial control, medical equipment or car display, TFT display plays an irreplaceable role. However, facing the dazzling array of TFT display products on the market, how to choose the most suitable model for you? TThis article will provide you with a comprehensive purchase guide to help you find the ideal TFT display.
Application scenario
The first step in choosing a TFT LCD display is to clarify the application scenario. Different scenarios have different requirements for TFT display screens, mainly reflected in resolution, brightness, contrast, response time, viewing angle, etc. For example:
- Consumer electronics: requires high resolution, wide viewing angle and high color reproduction LCD display screen to enhance the user’s visual experience.
- Industrial control: usually requires high brightness, strong anti-interference ability and wide temperature range display screen to adapt to complex industrial environments.
- Medical equipment: has strict requirements for color accuracy and high resolution to ensure the clarity of medical imaging.
- Car display: emphasizes high brightness and anti-reflective performance to ensure clear visibility outdoors and under strong light conditions.
Display parameter analysis
Understanding the core parameters of TFT display can help you choose the right model more accurately. Here are some key parameters:
- Resolution: Resolution determines the clarity of the displayed content. Common resolutions include 720p, 1080p, 2K, 4K, etc. The higher the resolution, the more delicate the display effect. Choose the appropriate resolution according to the usage requirements to avoid wasting resources.
- Brightness: The unit of brightness is cd/m² (nit). The higher the brightness, the better the visibility of the display in a strong light environment. Generally speaking, it is recommended to choose a brightness of more than 800 nits for outdoor use, while 400-600 nits is sufficient for indoor use.
- Contrast: Contrast refers to the brightness ratio between the brightest and darkest parts of the display. A higher contrast can enhance the image’s ability to express details. Common contrast ratios are 1000:1 or higher.
- Response time: The shorter the response time, the smoother the screen switching, which is suitable for scenes that need to play dynamic videos or animations. Generally, a response time of less than 8ms can meet most needs.
- Viewing angle: The viewing angle determines whether the image will be distorted when viewing the display from different directions. For scenes where multiple people are watching or multi-angle operation is required, it is recommended to choose a TFT display with a viewing angle of more than 170°.
Special functional requirements
Depending on the different usage environments, you may also need to consider the following functions of the TFT display:
- Touch function: If interactive operation is required, you can choose a TFT display with capacitive touch or resistive touch function. Capacitive touch screens are more responsive and suitable for consumer electronics; while resistive touch screens are more durable and suitable for industrial environments.
- Sunlight or night display: In special environments such as industry and medical care, the angle light function of the display during the day or at night is very important.
- Operating temperature range: Normal display screens can ensure stable operation at -20°C to 70°C, equipment working in extreme temperature environments, or a display screen that can operate stably in a wider temperature range of -30°C to 80°C.
Display interface type and motherboard compatibility
The interface type and compatibility of the display screen are also important factors to consider when choosing. Common interface types include LVDS, SPI, MCU, RGB and MIPI. When choosing, you need to ensure that the interface of the display is compatible with the motherboard compatibility output interface, and consider the data transmission speed and signal stability.
Brand and quality assurance
At Hongcai Technology, we recommend TFT display products that have been strictly tested and quality certified to ensure the reliability and stability of the products. Choosing products from well-known brands can reduce the risk of failure and extend the service life of the equipment. In addition, after-sales service is also an important factor in purchasing. High-quality after-sales service can provide you with long-term technical support and maintenance guarantees.
Price is also an important factor to consider when choosing a TFT display. On the premise of meeting the needs, choose the product with the highest cost performance. Displays with too low prices may have quality risks, while high-end products may have too many unnecessary functions. Therefore, it is recommended to find a balance between quality and price according to actual needs.
