"Low light high ash" is the brightness problem is the premise to ensure viewing comfort, user primary concern in the purchase of a small pitch LED product. In traditional LED display technology, led, reduce the screen brightness can cause loss of gray, and the loss of gray will directly affect picture quality, therefore, an important quality criterion small spacing is to reach a "high-low light ash "technical indicators. 2: Display Actual Size: Length 320mm × 9 = 2880mm = 2.88m or 320mm × 10 = 3200mm = 3.2m high 160mm × 12 = 1920mm = 1.92m or 160mm × 13 = 2080mm = 2.08m Screen size: L × H = 2.88m × 1.92m or 3.2m × 2.08m 3: Screen resolution: length 32 × 9 (or 10) = 288 height 16 × 12 (or 13) = 1924: display the number of pixels: 288 × 192 = 55296 The indoor led display, led display despite the length and width can be customized, but in general are in accordance with 16: 9 and 4: 3 ratio of production, because it is more in line with people's visual habits.
