Technical indicators of Electronic sand table
Pure plane display
LCD is the representative of flat panel display devices, which is a true flat panel display, completely free of curvature, large images, and distortion.
Uniform brightness, stable and non flickering image
Due to the fact that each point of the LCD maintains that color and brightness after receiving the signal, unlike CRT, which requires constant refreshing of highlights. Therefore, LEDs have uniform brightness, high image quality, and absolutely do not flicker.
120HZ frequency doubling refresh frequency
120Hz frequency doubling liquid crystal display technology can effectively solve the trailing and blurring during rapid image movement, enhance the clarity and contrast of the image, make the picture clearer, and the human eye is not prone to fatigue when viewed for a long time.
Longer service life
The service life of the backlight for ordinary NB, PC, and TV LED LCD screens is 10000 to 30000 hours, and the service life of the backlight for large lcd screen can all reach 60000 hours or more, which ensures the consistency of brightness, contrast, and chromaticity of each LCD screen used for mosaic curtain walls after long-term use and ensures that the service life of the curtain wall is not less than 60000 hours.
Adopt 3D high-quality image digital processing technology
3D digital comb filtering and 3D digital image noise reduction technology can greatly eliminate clutter interference and edge aliasing in image details.
Adopt RC intelligent adaptive digital processing technology
RC refers to adaptive control circuits such as DLC (Dynamic Scene Control), WLE (White Level Extension), and BLE (Black Level Extension). It is particularly suitable for night monitoring when the color to black camera outputs weak signals, and can automatically adjust the gray level and color temperature of the image, ensuring the authenticity of the image and effectively improving the depth of the scene.
Adopt H2S wide dynamic technology
Video high-definition wide dynamic synchronization adaptive dual bitstream technology can quickly adapt to processing high-definition video image signals at different frequencies, thoroughly solving the visual fatigue caused by image flicker at different frequencies.
In particular, the matching with the front-end special industrial control computer system has undergone professional testing and thoroughly resolved the distortion and attenuation during the secondary playback of the main control computer, eliminating the missing space after 1/2 signal sampling of the data. It is fully capable of automatically adapting to high-speed image signals under different field frequency states, achieving stability, clarity, and real-time performance of the image.

Adopt special edge sharpness image enhancement processing technology
Using a special image edge hooking circuit can greatly eliminate cross color, sawtooth, etc. on the image edges, making the image contour clearer and more hierarchical, thereby more effectively improving the clarity and sharpness of the image.
Adopt fast image capture technology
On the details of the captured person’s face, it can accurately distinguish wrinkles, scars, black stains, etc. on the face, without obvious tail dragging, ghosting, etc., making the restoration of skin color more realistic and realistic.
Intelligent automatic shadow elimination technology is adopted
When the input image is in a static state for a period of time, the system starts a “residual image elimination engine”, which automatically recognizes the static or moving status of the input image, judges the dynamic or static status of the currently displayed screen, and promptly issues commands to cause a certain amount of phase displacement in the horizontal direction of the still image displayed on the screen, thereby eliminating the possibility of liquid crystal molecules being damaged during the still image, Effectively extend the service life of the LCD screen.
High reliability, high stability, long service life, and low maintenance cost
Compared with ordinary LCD TV (display) LCD panels, industrial grade LCD panels use industrial grade power supply modules, low noise fan cooling systems, and operate continuously for over 60000 hours. LCD technology does not have any consumable equipment that requires regular replacement, so maintenance and repair costs are extremely low.
Electronic Sand Table product appearance
The surface coating of the metal shell should not expose the underlying metal, and there should be no bubbles, corrosion, scratches, coating peeling, and sand holes. A third-party inspection report certificate should be provided.
Electronic Sand Table product stability test
Under normal operating conditions, the equipment shall operate continuously for 168 hours without electrical, mechanical, or operating system failures. An inspection report from a third-party inspection agency is required.
