Answer: The core standard of an A-grade screen is no dead pixels, uniform color, sensitive touch, and no signs of aging. Generally, it can be preliminarily judged through appearance inspection, display testing, and software tools. For specific identification methods, please read the detailed identification methods below:

1、 Inspection of the appearance of the transparent OLED screen
a. Screen surface
- Scratches/Dents: Grade A screens should have a smooth surface without scratches and no bumps or cracks on the edges.
- Fitting process: Check whether the screen and the frame are tightly fitted without any glue overflow or gaps.
b. Display abnormality
- Bad pixels/bright pixels/dark pixels: In a pure black, pure white, red, green, blue or other monochrome background, observe whether there are pixels that are not luminous (dark pixels) or always bright (bright pixels).
- Light leakage: In theory, OLED is completely black when it is not emitting light. If there is whitening or halo when displaying black,
2. Display effect test
a. Color uniformity
- Display a pure color image (such as gray or white) and observe whether the screen has color spots, yellowing, or greening (commonly seen on aging or low-quality screens).
- Compare display consistency at different brightness levels (lowest and highest).
b. Viewing angle
- OLED screens should have wide viewing angles, and the color and brightness should not be significantly attenuated or cast even at a large tilt angle.
c. Image retention/screen burn-in
- After displaying a static image for a long time, switch the screen to observe whether there is any residual image (burn-in). Although A-grade screens may burn in due to aging, obvious residual images in the short term may be a low-quality screen.
3. Software Detection
a. Screen Test Tool
- Use professional apps (such as “Display Tester” and “Screen Test”) to detect dead pixels, touch response, color transitions, etc.
- Use tools such as “Device Info HW” to check the screen manufacturer (such as Samsung, LG, etc.), but please note that some manufacturers may block information.
b. Touch test
- Use the line drawing tool to check whether the touch is sensitive and whether there is any disconnection or failure in the edge area.
4. professional tool assistance
a. Microscope observation
- Check the pixel arrangement through a high-power microscope (such as Samsung Pentile and BOE’s “Zhou Dongyu arrangement”), but professional knowledge is required to determine whether it is consistent with the official specifications.
b. Color Accuracy Tester
- Use a colorimeter (such as SpyderX, X-Rite) to detect color gamut coverage (such as sRGB, DCI-P3), color accuracy (ΔE value), and other parameters. Grade A screens usually have a ΔE<3.
5. Brand and channel verification
a. Original certification
- For new devices, you can check the serial number through official channels to confirm whether the screen is an original accessory.
- For second-hand or replacement screens, pay attention to whether they are marked “original grade A”, but be wary of false advertising by merchants.
b. Purchase channels
- Give priority to official brand stores, authorized dealers, or reputable platforms to avoid low-price traps (screens that are significantly lower than the market price are high-risk).
6. Warranty and After-sales Service
- Warranty label: Original A-grade screens usually have official warranty labels or anti-counterfeiting codes(eg, Figure 1).
- After-sales policy: Screens purchased through formal channels generally come with a warranty of more than 1 year and support returns and exchanges for quality issues.

1. What sizes are available and can they be custom made?
Answer: 1.Currently available sizes are: P5 (1000x320mm), P6.25 (1000x400mm), P8 (1000x400mm), P10 (1000x400mm), P15 (390*990mm), P20 (1000x400mm)
2. Customized sizes can be produced. When the existing module size cannot meet the project requirements, customized sizes are required. Whether customized sizes can be produced requires discussion and consultation between our R&D department and production department to know whether it is feasible.
2. What is the transparency percentage and viewing angle?
Answer: The transparency percentage is 90%, and the viewing angle is 160°
3. What are the brightness levels,s, and can they be adjusted for different lighting conditions?
Answer: 2000 and 4000 brightness (add 1000 yuan/square meter). The brightness can be adjusted using software according to different lighting conditions
4. How are the screens connected to display content such as logos, images, or short videos?
Answer: Upload via mobile APP
5. What types of input sources are supported (e.g., HDMI, USB, Wi-Fi, cloud-based control systems)?
Answer: These input sources all support
6. Is proprietary software required to manage the display? If so, can you provide details on its capabilities and compatibility?
Answer: No proprietary software is required to manage the screen
7. Is it possible to sync multiple screens for a seamless, larger display?
Answer: Multiple screens can be synced for a seamless, larger display
8. Can the LED film screen be cut freely to fit the size of the glass surface?
Answer: Flexible LED film cannot be cut freely. After cutting, the circuit of the circuit board will be destroyed, which will affect the performance and stability of the product. The size can be customized according to your project requirements.
9. What is the peak power of each panel?
Answer: The peak power consumption of the flexible LED film screen is 600w/㎡
10. What is the average power consumption of each panel?
Answer: The average power consumption of a flexible LED film screen is 200w/㎡
11. Recommended control software (NovaStar, Viplex, etc)
Answer: Recommended control software: Novastar/Colorlight
12. Can the content (images or videos) you want to display be uploaded remotely?
Answer: The content (images or videos) you want to display can be uploaded remotely, but the prerequisite is that the sending box is connected to the Internet or has a 4G module.
13. Connectivity (HDMI, WIFI, Bluetooth, USB, etc)
Answer: Supports input sources such as HDMI, USB, Wi-Fi, cloud-based control systems, etc.
14. What file formats can be played?
Answer: A Flexible LED film screen can play various file formats such as text, pictures, videos, etc.

Answer: Yes, it is. the holographic LED display allows you to see what is behind the screen, with a transparency of over 80%.
Answer: If the holographic LED display you purchased is very cheap, and after using it for a period of time, the screen will be covered with a lot of dust due to magnetism, seriously affecting the display effect, then it is very likely to be a low-quality fake.
Kesytech holographic LED display is a genuine product. No matter how long it is used, the screen will not stick to dust, and the screen will not be magnetic. Long-term use will not affect the use of the screen.
When choosing a holographic LED display, you must keep your eyes open and choose a reliable source supplier like us to avoid pitfalls.
Answer: it is not recommended as that approach canbe more costly in the long run. TVs have limited functionality compared to typical kiosk displays or dedicated signage displays.
