When choosing a TFT LCD display interface, you need to consider multiple factors, including the size, resolution, transmission speed, cost, compatibility, and application scenarios of the display. Here are some specific selection suggestions:
Small-size display:
Usually refers to a display below 3.5 inches with relatively low resolution.
You can choose low-speed serial interfaces such as RGB, MCU, SPI, etc., which perform well at resolutions below 720P.
Medium-size display:
The size is between 3.5 inches and 10.1 inches, with a higher resolution.
You can choose interfaces such as MIPI, LVDS, and EDP. The MIPI interface is more commonly used in vertical screens, the LVDS interface is more commonly used in horizontal screens, and the EDP interface is often used for high-resolution displays.
Large-size display:
Usually refers to a display above 10 inches.
You can choose standard interfaces such as HDMI and VGA, which are easy and quick to use and can be used directly without conversion.
High-speed transmission requirements:
If the display needs to transmit high-resolution images or videos, you should choose an interface that supports high-speed transmission, such as MIPI, LVDS, EDP, etc.
The MIPI interface uses serial data transmission, which can achieve high-speed transmission at low power consumption, which is very suitable for high-resolution image requirements.
The LVDS interface is an efficient differential signal transmission method that can achieve high-speed data transmission at low voltage while reducing signal interference and transmission loss.
Low-speed transmission requirements:
For displays with low resolution and low transmission speed requirements, you can choose low-speed interfaces such as RGB, MCU, SPI, etc.
Cost factors:
The cost of different types of interfaces varies greatly, and the appropriate interface should be selected according to product design and budget requirements.
On the premise of ensuring performance, try to choose a lower-cost interface to reduce product costs.
Compatibility factors:
Make sure that the selected interface is compatible with other components used in the project to avoid problems that cannot be connected.
When selecting an interface, refer to the specifications of the display and the main control chip to ensure that the interface type and signal format match.
Mobile devices:
Mobile devices such as smartphones and tablets usually choose MIPI interfaces to meet the needs of high bandwidth, low power consumption and flexibility.
Industrial or medical industries:
These industries have high requirements for the anti-interference ability of the display screen. You can choose the LVDS interface, which can maintain good anti-interference ability when transmitting high-resolution data.
UHD resolution:
For ultra-high-definition resolution displays, you can choose the EDP interface, which uses a simpler connector and fewer pins to achieve high-resolution signal transmission, and has high transmission rate and excellent anti-electromagnetic interference.
In summary, when choosing a TFT LCD display interface, you need to consider multiple factors such as the size, resolution, transmission speed, cost, compatibility and application scenarios of the display screen. By weighing these factors, you can choose the interface type that best suits your product needs.
