Differences Between LCD Panel Grades and Their Impact on Pricing

LCD panels are usually classified into different grades based on pixel defects, brightness uniformity, color performance, surface condition, and overall stability. Although specific standards may vary slightly between manufacturers, panels are commonly divided into:

• Grade A

• Grade B

• Grade C

Each grade targets a different market and application.

Grade A panels are the highest quality level and are usually used in brand-new original products.

Main features:

• No bright dots, no dark dots (or extremely strict defect control)

• Uniform brightness and accurate colors

• No scratches, no pressure marks

• Long backlight lifetime and high stability

Typical applications:

• Brand TVs and monitors

• Medical displays

• Professional equipment

• High-end commercial displays

Price level:
Grade A panels have the highest price, but they also provide the lowest risk and best long-term reliability.

Grade B panels are widely used in the aftermarket and commercial projects. They may have very minor cosmetic or pixel defects that do not affect normal display performance.

Main features:

• May allow a few dark dots (no bright dots in most cases)

• Slight brightness or color variation allowed

• Fully functional and stable for continuous operation

• Very high cost-performance ratio

Typical applications:

• Advertising displays

• Industrial equipment

• Commercial monitors

• Large-scale projects with cost control

Price level:
Grade B panels are significantly cheaper than Grade A, while still maintaining good stability. This is the most popular choice for many overseas buyers.

Grade C panels usually have visible cosmetic defects or a higher allowance of dead pixels. These panels are mainly used for low-cost projects or temporary solutions.

Main features:

• Visible dark dots or pixel defects

• Possible scratches or uneven brightness

• Shorter backlight lifetime

• Higher risk of after-sales issues

Typical applications:

• Budget projects

• Short-term usage products

• Non-critical display environments

Price level:
Grade C panels offer the lowest price, but also come with higher quality risks. They are not recommended for long-term commercial or industrial use.

The price difference between panel grades mainly comes from:

• Manufacturing yield rate: Grade A panels come from the best yield section of production.

• Quality inspection standards: Higher grades require stricter testing.

• Backlight lifetime and stability: Higher-grade backlights last longer.

• After-sales risk: Lower-grade panels have a higher failure rate.

In simple words, you are paying not only for the screen, but also for stability, lifespan, and lower risk.

Before placing an order, buyers should clarify:

• What is the final application? (TV, advertising, industrial, medical, etc.)

• Is 24/7 operation required?

• Is the project more price-driven or quality-driven?

• What is the acceptable defect tolerance standard?

For most commercial and industrial projects, Grade B panels offer the best balance between cost and performance. For brand products and high-end equipment, Grade A is strongly recommended.

Different LCD panel grades directly affect display quality, lifespan, failure rate, and final product cost. Choosing the right grade is not about buying the cheapest panel, but about choosing the most suitable panel for your real application.

A professional supplier should clearly explain the grade, testing standard, and real condition of each panel—this transparency is the key to long-term cooperation.
