Abstract
The invention discloses a displayer for pushing overlapping display content by a serial communication interface and solves the problems that modes of displaying overlapping content by prior displayers are severely dependent on an operating system and software of a signal source device, the implementation is extremely complicated, and the cost is extremely high. According to the displayer for pushing the overlapping display content by the serial communication interface, the serial communication interface sends a received digital signal to a serial interface communication module digital signal input end, a digital signal output end of a serial interface communication module is connected with a digital signal input end of an instruction analyzing control module, a control signal output end of the instruction analyzing control module is connected with a control signal input end of an on screen display (OSD) overlapping display module, a display signal output end of the OSD overlapping display module is connected with a control signal input end of a display control circuit, and a display signal output end of the display control circuit is connected with a display signal input end of the displayer. The displayer is used for displaying the overlapping content.
Description
Technical field
The present invention relates to a kind of display, be specifically related to push by serial communication interface the display of Overlapping display content.
Background technology
The display source signal that existing all displays uses all is directly to transmit the mode of picture signal by RGB, VGA, DVI, HDMI etc., and can only show at one time the content of a signal source picture.The content that shows on the screen will depend on the display output of the equipment such as computing machine, video player.Play the word message that is superimposed upon on the existing picture or the whole demand such as picture color filter that changes if having in the normal display frame of display, usually need to depend on computing machine that signal source is provided, video processing equipment, display superimpose device etc.This mode depends critically upon operating system and the software of signal source equipment, implements very complicated and cost is high.
Summary of the invention
The present invention depends critically upon operating system and the software of signal source equipment for the mode that solves the demonstration stack content that has display now, implement problem very complicated and that cost is high, thereby proposed to push by serial communication interface the display of Overlapping display content.
By the display of serial communication interface propelling movement Overlapping display content, comprise serial communication interface, serial line interface communication module, instruction parsing control module, OSD Overlapping display module, display control circuit and display,
Described serial communication interface is sent to the digital signal input end of serial line interface communication module with the digital signal that receives,
The digital signal input end that the digital signal output end and instruction of serial line interface communication module is resolved control module connects;
The control signal output terminal that control module is resolved in instruction is connected with the control signal input end of OSD Overlapping display module;
The display output terminal of OSD Overlapping display module is connected with the control signal input end of display control circuit;
The display output terminal of display control circuit is connected with the display input end of display.
The present invention transmits literal and control signal by serial communication interface, the display that directly stack is intercutted Word message, changed the specific region color or Show Picture at ad-hoc location under existing normal demonstration.Having realized content that stack is intercutted can be fix, float, the display modes such as rolling or flicker.This implementation does not need to consider the complicated current conditions such as device type, operating system, the software and hardware of image signal source dispose, whether signal source works, and cost is lower.
Description of drawings
Fig. 1 is electrical structure synoptic diagram of the present invention.
Embodiment
Embodiment one, specify present embodiment in conjunction with Fig. 1, the described display that pushes the Overlapping display content by serial communication interface of present embodiment, comprise serial communication interface 1, serial line interface communication module 2, instruction parsing control module 3, OSD Overlapping display module 4, display control circuit 5 and display 6
Described serial communication interface 1 will receive the digital signal input end that digital signal that host computer sends is sent to serial line interface communication module 2,
The digital signal input end that the digital signal output end and instruction of serial line interface communication module 2 is resolved control module 3 connects;
The control signal output terminal that control module 3 is resolved in instruction is connected with the control signal input end of OSD Overlapping display module 4;
The display output terminal of OSD Overlapping display module 4 is connected with the control signal input end of display control circuit 5;
The display output terminal of display control circuit 5 is connected with the display input end of display 6.
The ability mode increases serial communication interface at display casing when making display, increase the circuit of serial line interface communication module, instruction parsing control module and OSD Overlapping display module at circuit.By the electronic circuit winding displacement these modular circuits are integrated together.Remaining display input also gets final product with normally display is the same with disposal system.
Present embodiment is in the picture of the normal display image signals of display source, can at any time word message and icon content Overlapping display had now on the picture by serial communication interface control, and can remind the beholder to note by change or the flicker of picture color.This implementation does not need to consider the complicated current conditions such as device type, operating system, the software and hardware of image signal source dispose, whether signal source works.Owing to used serial line interface, on wiring distance, cable cost, interface generality, great advantage arranged.
The described difference that pushes the display of Overlapping display content by serial communication interface of embodiment two, present embodiment and embodiment one is that the digital signal that described serial communication interface 1 receives comprises word content and steering order.
The described difference that pushes the display of Overlapping display content by serial communication interface of embodiment three, present embodiment and embodiment one is that the control signal that control module 3 outputs are resolved in described instruction comprises the control signal of the word message that superposes, the control signal of overlay drafting color and the control signal of superimposed image.
The described difference that pushes the display of Overlapping display content by serial communication interface of embodiment four, present embodiment and embodiment one is, when OSD Overlapping display module 4 was received the control signal of the stack word message that instruction parsing control module 3 is exported, OSD Overlapping display module 4 was with the control signal of output character message with the mode display text content of rolling or flicker;
When OSD Overlapping display module 4 is received the control signal of the overlay drafting color that instruction parsing control module 3 is exported, OSD Overlapping display module 4 will be exported the control signal that shows the arbitrary size zone in the optional position of current screen, and the control signal in described zone comprises with random color carries out the control signal of the transparent region that filter processes and the Region control signal of flicker;
When OSD Overlapping display module 4 is received the control signal of the superimposed image that instruction parsing control module 3 is exported, OSD Overlapping display module 4 will be exported the control signal of predefined image, and the control signal of described image is image, picture and icon are superimposed upon current screen with transparency, size and the position of appointment control signal.
