Product Details
350 cd/m brightness+3000:1 contrast:
A, core display parameters: define high-definition visual standards.
The scene adaptation value of 350 CD/m brightness: The wall-mounted advertising machine adopts professional LCD backlight module, and the brightness is stably maintained at 350 CD/m, and it supports manual/automatic adjustment of 150-350 CD/m (ambient light sensor is required). In a bright environment (such as a shopping mall window and an outdoor semi-open space), high brightness can offset the interference of external light and ensure that the color of the advertisement screen of the wall-hung advertising machine is saturated and not white; In low light environment (such as hotel corridors and night shops), lowering brightness can avoid glare and reduce energy consumption (every 50 cd/m decrease in brightness will reduce power consumption by 8-10W). According to the actual measurement, the brightness is within the viewing distance of 3-8 meters, and the picture clarity and visual comfort of the wall-hung advertising machine reach the best balance, which is suitable for most public places to watch scenes.
Image quality improvement of 3000:1 static contrast ratio:
By optimizing the pixel arrangement and backlight partition control of the LCD panel of the wall-mounted advertising machine, the static contrast ratio of 3000:1(Typ) is achieved, with deeper black and purer white. When playing brand advertisements with dark background, the details and gradient colors of LOGO can be clearly presented; When displaying the physical pictures of products, the texture of materials (such as metallic luster and fabric texture) can be accurately restored to avoid the problem of gray and white pictures. Compared with the contrast of ordinary advertising machine 2000:1, this parameter improves the layering of the picture by 40%, especially when playing text content (such as promotional information and service terms), the edge of the text is sharper, and it can still be clearly distinguished when viewed from a distance.
Basic configuration of unified display wall-mounted advertising machine: Full-size models (10.1-110 inches) all maintain the golden display ratio of 16:9, and the basic resolution is 19201080(FHD), and the resolution of 38402160(4K) can be selected for models of 27 inches and above; The refresh rate is stable at 60Hz, and there is no drag and jam when playing dynamic videos (such as product promotional videos and activity tidbits), so as to ensure that fast-moving pictures (such as car driving and people's movements) are still smooth and meet the requirements of high-frequency dynamic content playback in the advertising industry.
B. Aluminum alloy frame: structural guarantee for supporting high-definition display.
Material characteristics and display protection: The frame of the wall-hung advertising machine is made of 6063-T5 aluminum alloy, which is anodized to form a matte texture coating on the surface, which not only improves the anti-scratch and anti-fingerprint ability of the machine body (there is no trace of daily wiping), but also effectively shields some electromagnetic interference, reduces the influence of external signals on the display module, and avoids ripples and flicker in the picture. The thickness of the frame is 3-5mm (according to the size), and a protective frame with a width of 15mm is formed around the edge of the screen, which can buffer the impact of slight collision and protect the LCD panel inside the wall-hung advertising machine (especially for small-sized models with a size of 10.1-23.6 inches, so as to avoid bumping the screen during handling or installation).
Structural design and display adaptation: the aluminum alloy frame of the wall-hung advertising machine adopts the design of "reinforcing the four corners+hollowing out the middle", and reinforcing ribs are formed at the four corners by stamping process, thus improving the overall structural stability. Even for a large-size model of 65-110 inches, the frame will not be deformed due to its own weight for a long time, so as to ensure that the screen is always flat and avoid local stretching and distortion of the picture caused by the frame deformation. The frame and the screen are connected by buffer rubber strips, so that on the one hand, gaps are filled to reduce dust entry, on the other hand, slight vibration can be absorbed to protect the display module; Cooling holes (2cm apart) are reserved in the back frame to work together with the built-in cooling fan to ensure that the long-term running temperature of the display module of the wall-hung advertising machine is controlled within 45℃, so as to avoid the influence of high temperature on brightness and contrast stability.
