3 Appearance, Animation and Screen Control

Fonts and Text Styles

The font list mixes pre-installed and uploaded fonts, defaulting to one suitable for Chinese. Missing fonts fall back to the default automatically.

Uploading fonts:

• TTF and OTF, up to 10 MB each;
• uploaded fonts appear in the dropdown;
• list names come from file names — rename to English or digits beforehand, e.g. BrandSans-Bold.ttf, for readability;
• if the font's internal name differs greatly from the file name it may fall back; refresh the management page if an upload seems ineffective, and contact the supplier if it still fails.

Text colors use 6-digit hex like #FFFFFF. Bold, italic, underline and shadow are supported. Shadows suit dark backgrounds — don't stack too many effects or text blurs at a distance.

The "number font" in the column panel is column-level: changes sync to every number in the column and override number-level settings. To change one number only, select and edit it individually.

Column Background and Corner Radius

Column backgrounds use 8-digit hex #RRGGBBAA — six digits of color plus two of alpha, 00 fully transparent and FF opaque. Corner radius ranges 0~400 pixels.

Screen Background

• PNG, JPG and JPEG, up to 5 MB each.
• "Choose image": pick a local file, scaled proportionally to the screen and uploaded as the current background; mismatched ratios are padded with the default base color.
• "Upload image": re-uploads the image cached in the current browser — useful when the copy on the device is lost but this browser still holds the original.
• "Delete image": clears the background; the screen returns to the default base color.
• "Force stretch": stretches the image to fill the canvas — some distortion, but no letterboxing.
• "Show / hide background": affects the browser canvas only, for checking column placement while editing.

The device keeps only the current background. After a successful switch the old file is cleaned; keep local copies of anything worth keeping. If the stored image is lost, the editor reports "background file missing", the screen shows the default base color, and choosing or uploading again restores it.

Shake and Scrolling Marquee

Shake: enable "Shake" on a selected number and it wiggles slightly on the screen to urge pickup. The direction switches between vertical and horizontal. The animation loops on the screen side and costs no network bandwidth.

Scrolling marquee: once enabled, the number's content loops right-to-left inside its cell window, fitting longer notices like "please proceed to window 3".

• content up to 512 characters;
• text scrolls within the number's cell window, never covering neighbors;
• long content cycles through the window completely, not just the opening;
• three speeds — slow, medium, fast — with the speed buttons available only while the marquee is on.

Shake and marquee are mutually exclusive, with the marquee taking precedence: enabling one disables the other. Each number uses one animation at a time.

Screen On/Off and Working Hours (DPMS)

Choose under "Overall Settings" → "DPMS Control":

Automatic mode uses the "working hours" settings:

• start and end times in HH:MM format;
• the screen lights at the start time and blanks at the end time;
• crossing midnight is supported, e.g. 22:00 to 06:00;
• checked once per minute, so switching may lag by about a minute.

Default working hours are 08:00 to 22:00 — adjust to your business hours to avoid blanking during opening hours or staying lit overnight. Manual modes override the schedule until "Automatic" returns.

Blanking only turns off the display output — editing, saving and networking continue. Content can still be edited in the browser while blanked, and the newest picture appears at wake. Some monitors show "no signal" or a standby message after blanking; that is the monitor's own behavior — choose "Always on" or "Automatic", or wait for working hours to resume.
