What are the application directions of standard TFT screens?

Standard TFT (Thin Film Transistor) screens have shown extensive application potential in multiple fields due to their technological maturity, high stability, and cost controllability. The following are its main application directions and typical cases:

1. Consumer electronics products

Smartphones and tablets: TFT screens have become the mainstream choice for mid to low end smartphones and tablets due to their high resolution, fast response, and excellent color performance. For example, the demand for small and medium-sized TFT LCD screens in the consumer electronics field continues to grow, with global shipments reaching 2.6 billion pieces in 2020.

TVs and laptops: Large TFT LCD screens are used for high-resolution TVs and laptops to meet users' demand for high-definition display. Chinese manufacturers such as BOE and Huaxing Optoelectronics have approached the international advanced level in panel manufacturing technology.

Wearable devices: Low frequency LTPS-TFT technology can support 1Hz off screen display of smart wearable devices, significantly reducing power consumption, such as the application of ViSino's solution in smart watches.

2. Automotive Electronics

In car central control screen: TFT LCD screen is widely used in the field of automotive central control screen, especially the embedded touch TFT LCD display screen has become the mainstream trend due to its high integration and simplified supply chain. It is expected that by 2025, its shipment share in automotive central control screens will exceed 50%, mainly used for large screen displays of 10 inches or more.

Instrument panel and rearview mirror: The high brightness and high reliability TFT screen is suitable for car instrument panels and electronic rearview mirrors, improving the clarity of driving information display.

3. Medical equipment

Diagnostic instruments: The high contrast and stability of TFT LCD screens make them used in ultrasound diagnostic devices, electrocardiographs, and other equipment to help doctors accurately interpret data.

Monitoring equipment: Medical devices such as blood pressure monitors and thermometers rely on the stability and low-power characteristics of TFT screens to ensure long-term reliability.

4. Industrial automation

Industrial control panel: TFT screens are used in CNC machine tools, industrial robots, and process control systems to display real-time data. Their high toughness and anti-interference ability meet the requirements of industrial environments.

Human Machine Interface (HMI): Combined with touch technology, TFT screens simplify the operation process of industrial equipment. For example, the full screen under screen fingerprint technology of Dexin Array can integrate touch and display functions.

5. Smart Home and Internet of Things

Home appliance display panel: TFT color screen is used as the interactive interface for smart refrigerators, washing machines and other home appliances. LeSheng Semiconductor's display control chip has entered the supply chain of Midea, Xiaomi and other companies, promoting the upgrading of home appliance displays.

IoT terminals: Smart door locks, POS machines, and smart home devices achieve human-machine interaction through TFT screens. In the future, flexible TFT technology will further adapt to diverse forms of IoT devices.

6. Emerging fields and future trends

Flexible display: Flexible TFT screens are gradually being applied in wearable devices and foldable screen devices to meet the needs of being thin, lightweight, and bendable.

Smart City and Security: TFT screens are used for public information display, access control systems, and monitoring terminals, combined with touch technology to enhance interaction efficiency.

Summarize

Standard TFT screens continuously expand their application boundaries through technological iterations such as low-frequency LTPS and embedded touch, covering multiple fields such as consumer electronics, automotive, medical, and industrial. In the future, with breakthroughs in high-definition, low-power, and flexible technologies, their application scenarios will further expand, especially in emerging fields such as intelligent cockpits and IoT devices, with significant potential.
