The Research And Design Of 4K2K Display Technology And Human-computer Interaction Technology Based On Smart TV

With the development of smart TV,in order to keep up with the pace of smart TV's multi-function,4K2K display technology and human-computer interaction become the breakthrough in the study of smart TV.TV screen resolution is the direct sense perception to user.Image quality of 4K2K display can give user new visual experience.Nature and friendly human-computer interaction can make user control TV more fluent.At present,in the field of smart TV,research institutions at home and abroad have raised 4K2K display technology and human-computer interaction technology research boom.This paper mainly revolved around up-scaler of 4K2K display technology and gesture recognition and air mouse of human-computer interaction technology to study.Relying on the existing smart TV SoC single chip system platform in internship units,in order to solve the 4K2K sources shortage,a 4K2K signal processing module between the single chip system platform and Panel was designed,which used to complete the 4K2K signal frequency processing.And a new type remote control of smart TV was designed.The designed function of gesture recognition and air mouse remote control function can control smart TV smoothly.The main research work includes the following three aspects:(1)A 4K2K signal processing module was designed based on MStar 6M40.It not only supported 4K2K signal to display without loss,but also supported FHD signal changing to 4K2K signal to display through up-scaler,which can solve the problem of lack of 4K2K video source.V-by-One interface was used in 4K2K signal processing module.(2)A new gesture recognition design scheme was proposed,which gesture recognition module was integrated in remote control of smart TV.Aiming at the current gesture recognition camera installed on the TV,the influence of distance and angle of view exit along with the problem that gesture recognition rate is low.Gesture recognition module was integrated in remote control can solve the problem.Compared with gesture recognition installed on TV,gesture recognition module integrated in remote control can be moved,which make users won't be influenced by the distance and angle of view.(3)A new multi-function and low cost remote control design scheme was proposed.Aiming at the current that the remote control of smart TV with single function,absolute positioning air mouse function was designed in the remote control,which used the same MCU module with gesture recognition function as mentioned above.So the designed remote control was equipped with the function of gesture recognition and air mouse.The function of gesture recognition and air mouse was designed in exclusive mode,which can reduce power consumption.
