Wall mounted advertising machine

C, coordination of protective panel and display effect
The picture quality balance of the wall-hung advertising machine protected by 4mm tempered glass: the screen surface is covered with 4mm thick tempered glass panel, and after special optical treatment, the light transmittance reaches 92%, which hardly affects the presentation effect of 350 CD/m brightness and 3000:1 contrast. Toughened glass has hardness up to Mohs 7, which can resist scratching by hard objects such as keys and coins, and has anti-glare function (surface AG atomization treatment). Under strong light irradiation (such as under the skylight of a shopping mall), it can reduce the reflective area, ensure the consistency of brightness and color of the picture when viewed from different angles, and avoid the local picture being unclear due to reflection.
