The high-brightness LCD screen has become popular rapidly in recent years, mainly due to the superposition of the four driving forces of technological breakthroughs, scene rigid needs, mature industrial chains, and policy catalysis. The following is analyzed from four dimensions: technology, market, application, and trend

The reasons for its popularity:

   Technological Breakthrough: A Revolution in the Balance of Brightness and Energy Efficiency**

1. **LED Backlight Upgrade**

- The brightness of traditional LCD screens is generally 300-500nits, while the brightness screen is increased to **1000-3000nits** (such as industrial-grade screens up to 5000nits) through technologies such as dual CELL structure and high-density LED lamp beads.

Break through the bottleneck of outdoor bright light visibility.

- **Mini LED backlight technology** popularized (such as BOE P0.9 products) to achieve finer zonal light control, the contrast ratio is increased to 1,000,000:1, and the power consumption is reduced by 30%.

2. **Optical Film Technology Iteration**

- Material innovations such as anti-reflective (AG/AR) coating and brightness enhancement film (BEF) make the reflectivity of the screen less than 2% in strong light (about 8% for ordinary screens), significantly improving outdoor visibility.

3. **Driver IC Optimization**

- Dynamic backlight adjustment algorithms (such as local dimming) achieve adaptive brightness, taking into account the needs of highlighting and energy saving, and extend the service life to **100,000 hours** (about 50,000 hours for ordinary screens).

### **Second, the scene just needs: from outdoor advertising to the outbreak of smart cockpit**

**1. The Digital Wave of Outdoor Advertising**

- According to Statista data, global out-of-home digital advertising spending will reach $41.7 billion in 2023, an increase of 23% year-on-year, and high-brightness screens have become the first choice for advertising machines due to their anti-glare and long life.

- **Case**: Focus Media's elevator advertising screen has been fully upgraded to a 2000nits high-brightness screen to ensure the playback effect in a strong light environment.

#### **2. The Smart Car Display Revolution**

- The brightness requirement of the on-board screen has been increased from 500nits to **1500nits** (to cope with direct sunlight), and the Tesla Model S Plaid is equipped with a 17-inch 2200nits central control screen, which has led to the upgrading of industry standards.

- **Penetration rate**: In 2023, the installation rate of high-brightness screens of new energy vehicles will exceed 60% (vs 20% of traditional vehicles).

**3. Industrial & Medical Professional Scenarios**

- Industrial HMI equipment needs to be clearly displayed in a strong light workshop (≥1000nits), and medical surgical screens need to be bright and accurately color rendering (such as DICOM standards), which promotes high-end customization needs.
