Patchwork Truth

8mm patchwork-the best balance between visual coherence and cost

Don't blow "seamless", just talk about whether you can see it from your viewing distance.

  • Patchwork definition:8mm refers to the total width of bilateral patchwork (single screen 4mm 4mm), specially designed for 3-5 meters viewing distance
  • Visual experience:From the appearance of 3 meters, the 8mm seam is almost invisible. There is no feeling at all from 5 meters away.
  • Cost advantages:Compared with 3.5mm / 1.8mm / 0.88mm ultra-narrow patchwork seam, the cost is 30-40% lower
  • Industrial grade panel:LG / BOE original VA/IPS panel, 500nits brightness, 24/7 continuous operation
Tell us frankly (we do not avoid):
  • 2 meters close view, visible patchwork
  • Light solid background (such as white PPT) is more likely to expose patchwork than dark content
  • When text is displayed across the screen, patchwork has obvious influence, while video/picture has less influence.
  • It is suggested that the content design should avoid the patchwork area, and we provide the content avoidance design suggestion.

The real difference of the same picture in different patchwork width and viewing distance

Patchwork Selection Guide-Don't spend more money on the narrow patchwork you won't use.

Patchwork widthApplicable viewing distanceApplicable scenariosCost comparison
0.88mm1-2 metersControl room, high-end showroomHIGH (REF)
1.8mm2-3 metersCorporate lobby, conference roomMedium-high (+15-20%)
3.5mm3-4 metersRetail stores, showroomsMedium (+25-30%)
8mm3-5 metersCorporate lobby, retail, conference room, command centerLow (baseline)
"8mm patchwork is not a compromise, it is just enough. Under the viewing distance of 3-5 meters, 30-40% of the budget spent on 3.5mm will not bring perceptible experience improvement."
Image quality

65 "4K Ultra HD-text and graphics can be seen from a distance

The big screen is not "watching the excitement from a distance", but still sharp from a distance.

Qtenboard 65英寸4K拼接屏与1080P屏幕5米外清晰度对比

5 meters away: sharp edge on the left 4K vs obvious weakness on the right 1080P

  • 4K UHD resolution:3840 × 2160, you can see words, maps and data charts from 5 meters away.
  • 500nits high brightness:Corporate lobby, retail stores with natural light environment is still clear
  • High contrast 4000:1-8000:1:Dark background content (monitoring screen/data large screen) display more transparent
  • Wide viewing angle of 178 °:There are no blind spots on the side and the back row, and the audience on both sides can also see clearly.
  • Anti-Glare Panel:Reduce ambient light reflections for improved all-weather visibility
Brand promotional film, enterprise introduction, data large screen, map command interface--Details of 4K content on 65-inch splicing screen, 1080P all-in-one machine cannot be replaced.
Reliability

24/7 stable operation-industrial quality, no fear of long-term use

The large screens of the command center and monitoring room cannot be "asked for leave" 365 days a year"

  • Industrial grade panel:VA/IPS industrial LCD panel, industrial certification
  • 24/7 continuous operation:Support 7 × 24 hours uninterrupted work, specially designed for monitoring/command scene
  • Long life:50,000 hours, 8 hours per day for more than 17 years
  • Wide temperature and humidity:Working temperature 0-60°C, humidity 20-80%
  • Low power consumption:Typical 76-120W, standby <0.5W, long-term operation of electricity controllable
  • Low failure rate:<1%, 40-50% lower than the industry average
What about non-industrial screens?Ordinary commercial screen brightness attenuation, afterimage, color cast after 3-6 months of continuous operation; industrial-grade panel with high temperature capacitor, heat dissipation optimization, dustproof design, long-term operation of stable picture quality.

To whom are you speaking?

Role-based persuasion -4 types of decision makers, each taking what they need

Procurement, IT, usage, management-each role cares differently

01

Procurement/Administration

Core concerns: Budget, TCO, lead time

20-25% lower than the same configuration, 25 days delivery, can be extended in installments.

"Covering a larger area within budget"

02

IT/Technology

Core concerns: signal compatibility, control methods, O & M

RS232 LAN dual control, Daisy Chain simplified wiring, SDK open

"One set of backstage tube all screens"

03

Using Department

Core concerns: display effect, convenient operation

8mm patchwork 3-5 meters almost invisible, multi-window roaming, remote control ready to use

"Can't see the splicing, the operation is as simple as TV"

04

Management

Core concerns: ROI, brand image

5-year TCO is lower than projection splicing, large screen improves enterprise appearance and reception grade

"It's not spending money, it's investing in corporate facade"
