Can the audience read the intended content?
The most revealing display sample is the smallest text, symbol or image detail the audience must read. Pair that content with audience positions, movement and light conditions. A demonstration on the proposed configuration can then address a defined viewing requirement.
A public-information screen may depend on readable detail more than the area of a promotional image. Finer pitch can provide more pixels at a given active size, but content design and site conditions still affect legibility. The screen specification needs actual active width, height and resolution.
The KEEYAK LED advertising truck page lists 3.5 to 13 m² display-area references and pitch options P2.6, P3, P4, P5, P6, P8 and P10. These are catalog choices, not a statement that every area, mechanism and pitch combination is available as one installation.

| Requirement | What to put in the brief | Evidence in the proposed package |
|---|---|---|
| Close viewing or detailed text | Audience positions and sample content | Active resolution and a relevant viewing demonstration |
| Wider event viewing | Audience area, content and light conditions | Display arrangement and specified brightness-control scope |
| Lifted or rotating display | Deployed position and site restrictions | Exact mechanism, support arrangement and operating limits |
| Long sessions | Duration, supply and installed equipment | Electrical load, cooling and service requirements |
Confirm the screen package behind the area figure
The screen package should identify the display model or components, active dimensions, pitch, controller, signal interfaces and playback functions. Content preparation and delivery also need an agreed workflow, including software and service responsibilities left to the buyer.
Maintenance access, replacement-module identity and supporting documents are important differences hidden by a screen-area figure. Unit LED's billboard-truck guide covers display specifications and purchase-versus-rental questions. Its market prices and package claims are not terms or performance evidence for a KEEYAK installation.
Where an offer claims protection or environmental suitability, ask for the applicable equipment identity, test or rating and its installation conditions. KEEYAK's catalog includes an equipment-temperature range with its covered equipment still to be confirmed. Do not treat that field as a guarantee that every display, controller or completed truck can operate throughout it.
Put the supporting loads into the power schedule
Displays share the electrical supply with controllers, playback equipment, lighting, cooling and any included audio system. The load schedule and expected operating conditions should determine the proposed supply arrangement. Screen area alone cannot size that package.
KEEYAK lists forced ventilation and optional air conditioning. The quotation should state what is fitted and how the body and equipment will be cooled during the specified session. Ambient conditions, the enclosure and stationary operation belong in that assessment.
External power, onboard generation and other supplies need explicit inclusion or exclusion. The offer should assign connection and changeover responsibilities at the destination, with operating duration, maintenance access and consumables considered together.
Establish where and how the display will deploy
A lifting or rotating display needs an exact mechanism and a documented installation. Stowed and deployed dimensions, support requirements and permitted conditions must cover the intended site. A feature label alone leaves wind, ground and clearance limitations unanswered.
Local parking, road-use, advertising, audio and event permissions can constrain the layout and activity. The operator should establish those restrictions for the intended deployment and include them in the brief. Road travel permission alone does not establish permission to show content or deploy equipment at every site.
Use the quotation-comparison guide to compare chassis, body, display, controller, power, cooling, lifting equipment and commissioning on the same basis. The pre-delivery checklist helps record the equipment identities and agreed demonstrations.
LED truck purchase questions
Is the smallest pixel pitch always the best choice?
Select it with the active screen dimensions, audience position and actual content. Ask for a relevant demonstration. The pitch label alone does not determine whether the message will be legible or justify a more expensive screen package.
Does the listed display area include every screen on the vehicle?
Confirm the number of screens and the active dimensions of each. Ask whether the quoted area is per display or a combined figure, and identify any fixed, lifting or rotating sections separately.
Should a fleet buy a vehicle or hire an advertising service?
Compare your deployment frequency, staff, content production, maintenance and local permissions with the service scope offered by a provider. A purchased screen truck supplies equipment; it does not guarantee campaign reach, audience response or advertising revenue.
