Outdoor LCD Readability: A Site Test Checklist Before Sign-Off
Can the intended reader find and understand the message where the display will be installed? Make that the starting question for a readability test. A useful acceptance record ties the content, viewing position and site conditions to what the project team actually observed.
This checklist helps buyers and integrators plan that review. It does not prescribe a universal brightness level, text size or viewing distance, and it does not confirm the performance of a JIAMIAI LCD model. Agree the proposed configuration and test conditions with the supplier.
1. Define the reading task
Choose a task that matches the display's purpose: identifying a building, finding a platform, reading an opening time or recognizing a temporary notice. State which part of the message the reader must understand and where they need to be able to do so.
Record whether the intended audience will usually stand, wait or walk past. Include the relevant languages and any symbols. Keep the task specific enough that two observers can report comparable results rather than simply calling the screen “clear.”
2. Mark the viewing positions
Use the site survey to select observation points on a plan. Include the normal approach route, the intended reading location and any side approach that matters to the project. Record approximate distance, observer position and obstacles at each point.
- Check from positions that people can normally use without stepping into a restricted area.
- Include relevant seated and standing viewing positions in the agreed test.
- Note doors, landscaping, parked vehicles or temporary furniture that obstruct the message.
- Keep the same observation points when comparing revisions.
Confirm how the chosen freestanding, wall-mounted or transit display format affects these positions. If the installation location changes, review the test plan rather than reusing the earlier result automatically.
3. Use representative content
Test the messages the operations team expects to publish. Include the longest routine heading, a typical information page, directional symbols and the relevant language characters. Use the intended layout and orientation on the proposed display configuration.
Ask observers to read the essential message and describe the action it suggests. Record cropped text, unclear symbols, missing characters or confusion between headings and supporting details. For rotating content, check whether the agreed reading task can be completed before the message changes.
Change one content variable at a time when investigating a problem. For example, simplify the wording and retest from the same position before deciding whether another layout or display format needs assessment.
4. Record light conditions and reflections
Plan observations for the light conditions relevant to the site. Record the date, local time, weather, screen orientation and visible reflections. If the location operates after dark, include an evening review with the responsible site team.
Ask the supplier to document the display settings used during each test and any supported automatic adjustment mode. Where a setting change is proposed, confirm that it is permitted for the actual configuration and repeat the agreed observations.
A photograph can help identify the position and conditions, but keep it alongside the observer's findings. Do not treat an image captured under one set of conditions as proof that every planned reading task has been met throughout the operating day.
5. Keep unresolved conditions visible
If the visit does not include a relevant condition, mark it as untested. For example, an overcast afternoon review should not be recorded as a completed direct-sunlight test. Agree whether a follow-up visit, further supplier evidence or a different assessment is needed.
Separate observations about readability from claims about environmental suitability or accessibility compliance. Ask the appropriate specialists to define any applicable project requirements and evidence. This planning checklist is not a compliance assessment.
6. Close each issue with a repeatable check
For every observation, record the task, location, content version, settings, conditions, result, responsible party and next action. Use explicit outcomes such as accepted, requires revision or not yet tested.
After a change, repeat the affected test and retain the earlier record. If the supplier proposes different equipment or positioning, update the scope and acceptance checklist before final agreement.
