| This article explains the marketing of 3840x2160 UHD multi-function display.And the solutions for the issues which are met during development and testing.By the analysis the current marketing of the display.We can find that the shipment is getting lower.But it is getting higher in UHD display.The manufacturer which is still selling the FHD displays should consider to develop an UHD display and the get into the marketing quickly to keep the competitiveness.The development process can be separated into hardware and software.The most important feature of UHD display is to send the huge data in high bandwidth for the high resolution.So the layout for the hardware must be designed to guarantee it can support the UHD display.For now,only the DP V1.2 can reach the 21.6Gbps/s bandwidth for the UHD display.So for the UHD display,DP is mandatory and it will be the most important connecter of the display.Of course,it will be keep down compatible for the resolution 1920x1080,1366x768,1600x900...etc.Depends on the hardware circuit design,by modify the parameters of EDID to communicate with host and let it can out the UHD resolution.By the software initialize for the I/O to read the EEPROM data and deal with the signal.Finally,it will output the UHD resolution to the display panel and then the end user can see the real UHD.For the software development,for the low blue light,display scaling and ECO...etc.To make the display can support UHD and also has more features for end user's requirement.Basically there will be testing for the UHD display when it is finished.During the testing process,will depend on different functions,choose different testing equipments with different methods to verify the display for its design,reliability and compatible.For the using of the equipment,design concept and testing process...etc will be discuss and list in this article.And also introduce for the problem analysis and solution then finally the UHD display can be finished done and can meet the expected requirement. |
