As a mainstream display technology, liquid crystal screen (LCD) has both advantages and disadvantages, depending on the application scenario and technology iteration (such as Mini-LED backlight improvement).

The following is a comprehensive comparative analysis to help judge its advantages and disadvantages:


**First, the core advantages of LCD screen**

1. **Cost & Accessibility**

- Mature technology, perfect industrial chain, low production cost, covering from low-end to high-end market.

- Suitable for mass consumer electronics (TVs, monitors, tablets, etc.), cost-effective.

2. **High Resolution & Fine Display**

- High pixel density, suitable for displaying detailed content such as text and charts, and obvious advantages in office scenarios.

- The IPS panel provides a wide viewing angle (178°), which is less prone to color casts when viewed by multiple people.

3. **Brightness & Light Resistance**

- Wide range of adjustable backlight brightness, Mini-LED backlight technology further enhances peak brightness (more than 2000 nits), suitable for outdoor or bright light environments.

- Anti-reflective coating technology reduces ambient light interference.

4. **Life & Stability**

- There is no screen burn-in problem of OLED, and the display stability is higher for long-term use.

- Long backlight life (more than 50,000 hours), suitable for industrial, medical and other scenarios.

5. **Power consumption is relatively controllable**

- Lower power consumption when displaying white screen compared to OLED (global control of backlight).

**Second, the main disadvantages of LCD screen**

1. **Contrast & Black Performance**

- Relies on backlight, blacks can't be turned off completely, and contrast ratios are much lower than OLED (typical LCD contrast ratio 1000:1, OLED up to million:1).

- Darkfield images are prone to "graying", which affects the HDR effect.

2. **Response Speed Limit**

- It takes time for liquid crystal molecules to deflect, and the response time of traditional LCD (4-8ms) is lower than that of OLED (0.1ms), and high-speed images may be delayed

(games, sporting events).

3. **Viewing Angle & Color Uniformity**

- The VA panel has a narrow angle of view, and the color shift in the side view is noticeable.

- Uneven backlighting at the edges can lead to "dark areas in the four corners" (common on low-end screens).
