Description
Technical field
This utility model is related to TV domain, particularly a kind of frequency error compensation ultra high-definition TV.
Background technology
Full HD is for the screen resolution of flat panel TV, it is necessary to while meeting two conditions：One is screen
Physical resolution be that the resolving power for meeting 1920 × 1080, i.e. horizontal direction will reach 1920 pixels, vertical resolution will
Reach 1080 scan lines；Two is the picture signal that television internal circuit can process and export 1080p forms.Full HD finger is shielded
The intrinsic physical characteristics of curtain, do not change because signal picture changes, and no matter played is on cable television, DVD video discs or PC
HD video, full HD TV remain 1920 × 1080 physical resolution.
Full HD TV in prior art, digital signal before input TV itself usually there will be certain frequency and miss
Difference, after input TV, need to carry out frequency error compensation, otherwise can high degree impact picture quality, definition decline compared with
Many, while side entering-type LED backlight is adopted existing display screen more, cause television color gamut coverage rate and brightness uniformity poor, cause
TV image saturation and fine and smooth degree all decline much, it is difficult to meet the requirement of client.
Utility model content
For the problems referred to above, the utility model proposes a kind of frequency error compensation ultra high-definition TV.
For solving above technical problem, the technical scheme that this utility model is provided is:
A kind of frequency error compensation ultra high-definition TV, it is characterised in that including display screen and mainboard, the mainboard includes controlling
Processor processed, digital to analog converter, three primary colories sensor, frequency compensation module and LED drive module, the frequency compensation module bag
Include band separation filter, signal compensator, carrier synchronization device；
The mainboard is provided with image input port and output end of image mouth, described image input port, digital to analog converter,
Frequency compensation module is sequentially connected, and the frequency compensation module is connected with control process device, the band separation filter, signal
