Mobile SMD Screens: The Rise of LED “Video Vans” in Pakistan
Mobile SMD screens mounted on vans, trucks and trailers let advertisers take moving digital content to different locations. This guide…

Election periods in Pakistan bring large public gatherings, from big rallies (jalsas) in city parks to smaller community meetings and press conferences. Organisers of these events, whatever their party or affiliation, face the same practical problem: making sure people far from the stage can see and hear what is happening. That is why many events use SMD screens for political campaigns and other large gatherings.
At a large rally, many attendees stand far from the stage. A good sound system carries voices, but people at the back may not see the speakers at all. Large LED screens placed through the venue let more of the audience see the stage clearly.
This guide is about the equipment: which types of SMD screens for political campaigns suit different events, what to consider for outdoor and indoor use, and the safety and regulatory points organisers must keep in mind. SMDLED supplies equipment on a neutral basis and does not advise on campaign strategy.
Large public gatherings in cities like Lahore, Karachi and Peshawar can cover big areas. A public address (PA) system carries sound, but visibility drops off quickly with distance.
A common solution is a main screen beside or behind the stage, plus additional “delay” screens placed further back in the venue, mounted on properly engineered structures. These show a live camera feed of the stage so people at the back can see the speakers. Audio and video timing should be aligned so the picture matches the sound at each screen position.
Good visibility helps attendees follow the event. Screen positions should be planned with the event’s safety team so that structures do not block sightlines, exits or emergency routes.
Screens are a visual medium, so they can display graphics and text alongside the live feed, such as the event name, programme timings and general information.
Before speakers arrive, screens can show pre-recorded content. Any content shown, including information about voting, must be accurate and comply with the Election Commission of Pakistan’s code of conduct and other applicable rules; this is the responsibility of the organiser.
For readability, keep text large, use high-contrast colours, and allow enough time on screen for people further away to read it.
Not every event takes place at a large venue. Some organisers use LED screens mounted on vans or trailers for smaller gatherings where a full stage setup is not practical.
Mobile screens are covered in more detail in our guide to mobile SMD screens and video vans. In short, they should be operated only at approved locations, following traffic rules, local authority permissions and noise limits, and without causing distraction to drivers.
Organisers are responsible for obtaining the necessary permissions for where and when mobile screens are used, and for ensuring that audio is kept within permitted limits, especially in residential areas.
Outdoor events in Pakistan may face strong sun, heat, dust, rain and wind. Equipment must be suited to these conditions, and plans must include what to do if the weather turns.
Indoor screens are not bright enough for daytime outdoor use and are not weather-protected. Outdoor events need outdoor-rated screens with enough brightness for daylight.
For outdoor use, the BIA Outdoor SMD Screen Module is one option.
Weather-rated modules are only part of the picture. Screen structures and scaffolds must be designed by a qualified engineer for the screen’s weight and expected wind loads, and installed by experienced crews. The event plan should set wind and weather limits; in high winds, storms or lightning, screens may need to be switched off, lowered or the area around them cleared.
Many events take place indoors, such as town hall meetings, dinners and press conferences. These need a different setup from outdoor rallies.
For press conferences and indoor events, an LED backdrop can show logos, titles or presentation content. For events that will be filmed, choose screens with high refresh rates so they look good on camera.
For indoor events, the BIA Indoor SMD Screen Module is one option.
For high-resolution indoor backdrops, the BIA HDR 4K LED Video Wall is another option.
Indoor LED backdrops can give events a clean, professional look on camera.
Large gatherings carry real safety risks, including overcrowding and medical emergencies. Crowd safety depends mainly on venue design, capacity limits, stewards, police and medical teams, and a clear emergency plan agreed with the authorities.
Screens can support that plan. If the control position is set up for it, the event’s safety team can replace the live feed with safety messages, such as directions to particular exits or instructions to stay calm, alongside PA announcements and stewards.
Pre-prepared safety slides and a clear chain of command for who can switch to them make this more effective. Screens should be powered in a way that the safety plan accounts for, and should not be relied on as the only means of emergency communication.
Many events today combine the physical gathering with online channels. Technically, screens can show live streams, approved social media posts or messages from attendees.
If social media content is shown, it should be moderated before it appears on screen, and organisers should respect people’s privacy and the applicable rules on campaign content. Displaying attendees’ photos or posts should be done only with their permission.
From the equipment side, this needs a media server or switcher that can combine these sources with the stage camera feed.
Organisers need to budget carefully. Screen costs depend on size, pixel pitch, indoor or outdoor type, structures, power, cameras, crew and the number of event days.
For large outdoor events, screens are often one of the main ways people at the back can follow proceedings, so it is worth budgeting for adequate size and brightness.
LED screens are reusable, so for a series of events, renting or buying may be compared based on the number of events and logistics. You can view our hardware on the Products page and ask us for quotes for your specific requirements.
Live events leave little room for error, so reliability matters. Ask suppliers what spares, backup playback and technical staff they provide on site.
Choose a supplier with suitable equipment and experienced crews. SMD LED Screen Pakistan supplies indoor and outdoor LED screens and can advise on suitable equipment for your event.
Key points to discuss include power backup, structural design for wind, and colour calibration. You can follow our updates on our Official Facebook Page.
For large gatherings, well-planned SMD screens for political campaigns and similar events can provide:
With suitable equipment, careful planning and attention to safety and the rules, screens can help large audiences follow an event clearly.

1. Why are screens used at large rallies?
At large gatherings, many attendees cannot see the stage. Screens placed through the venue show a live feed of the stage so more people can see the speakers.
2. Can outdoor screens cope with summer heat and rain?
Outdoor-rated modules such as the BIA Outdoor module are designed for outdoor conditions, but performance also depends on the structure, power setup and installation. Follow the manufacturer’s limits and the event’s weather plan; in storms or high winds, screens may need to be switched off or lowered.
3. Can mobile screens be used during election periods?
Where permitted, yes. Organisers must follow the election code of conduct, traffic rules, local authority permissions and noise limits, and operate screens safely.
4. Can screens be used indoors for press conferences?
Yes, using indoor screens such as the BIA Indoor module or BIA HDR 4K LED Video Wall. Choose a high refresh rate if the event will be filmed.
5. How can screens help with crowd safety?
Screens can display safety messages and exit directions as part of the event’s emergency plan, alongside PA announcements, stewards and the authorities. They support crowd safety but do not replace proper planning and staffing.
