Digital Signage Displays
Large digital signage displays are very popular and are widely used in multiple industries to display certain important information on large flat screens placed in useful locations.. They are used in hospitals, conference rooms, factory floors, retail shops , restaurants, hotels and many places.
We can build inputs for an elegant digital signage using AppSheet and display app data for the intended users in the form of digital signage. The app 's view can be cast on a large TV screen or monitors that can accept remote input.
The sample app below shows a dashboard view being used as a digital display signage built with an AppSheet app.
Change the display dashboard by using Appsheet webhook API to avoid sync screen disturbance

The important thing to note is that the data table behind the dashboard view is updated using an AppSheet API webhook. With this implementation, the view does not need a force sync of the entire view that can be glaring to the viewer. With Webhook API, when the underlying data changes in the other data tables of the app, the webhook seamlessly changes the data in the table of the digital signage dashboard.
One could alternatively try to use "Quick Sync" feature to seamlessly update the digital signage display.. However quick sync feature has certain limitations. So it may not be possible to be used in all apps.
Sample digital signage display. A factory shop floor production plan and company news / updates display
The sample digital display's entire screen looks like below. The left hand side is the production plan for the shop floor of a company for three products ( desktop, laptops and tablet pcs). When the production numbers are updated in the app, those reflect on the :digital signage display that can be placed in the shop floor.
On the right hand side, there are some company news cards that can be shown on the display screen. These company news updates can be changed at predetermined time interval of say 10, 15 minutes by running scheduled bots.
Views' Overview
The "Production Plan " view as well as "Company News" views in the dashboard view are created using Card views. There some SVG code in the "Production Plan" view to create the images showing product items and numbers.
The GIF below shows that when the quantity for the actual production for the desktops changes from 222 to 300 its status color changes to yellow ( meaning a reasonable target completed.)
The slight flicker in the GIFs below are because of GIF recording.
The GIF below shows when the laptops' production is changed to a higher number the actual number status changes to green.
The GIF below shows for tablet PCs when the planned target is increased, the actual number starts showing red.
The concept could be extended to many other industries and businesses. I tested by casting it on a 32 inch TV and it works well.
