Features

• Adopt narrow frame design, UHD LED LCD screen, display resolution of 3840*2160, display ratio of 16:9, with anti-glare effect; can work normally under high illumination (110K Lux) environment.
• With rich color details of display and high color reproduction (color gamut ≥ NTSC 85%), the demonstration picture can be presented delicately.
• More than 128 grayscale resolution level of the display ensures the sharpness and layering of the screen display effect.
• Use fit technology without zero distance for paper-like writing experience. The surface tempered glass (7H hardness) can effectively protect the screen, and reduce the polarization and scattering between the panel and the glass, so that the screen display is clearer and more transparent, and the viewing angle is wider.
• With blue light reducing function, which can be activated by touching the menu button with one key.
