Abstract
The present invention relates to the method improving the display of 4k2k screen reliability, comprising: by software control, delayed startup mark is arranged to 4k2k screen; According to described delayed startup mark start-up study counting in the integrated circuit (IC) bus circulation process of primary control program, in the process of time delay counting, judge if the current state of 4k2k screen is different from arranging of preservation, then to 4k2k screen sending controling instruction, reset each state variable, remove described delayed startup mark simultaneously, otherwise according to arranging of preserving, 4k2k screen is controlled.Method of the present invention, the situation that effectively can reduce 4k2k screen control exception occurs, and significantly improves the reliability of screen display, improves the viewing experience of user, the display quality of 4k2k screen is had further lifting.
Description
Technical field
The present invention relates to Display Technique, is the method improving the display of 4k2k screen reliability concretely.
Background technology
4K2K is a kind of abbreviation of high definition display resolution.On market general using 720P as high definition standard, current technical HDTV (High-Definition Television) resolution is 1280 × 720,4K2K ultra high-definition then reaches the physical resolution of 3840 × 2160, common FullHD(1920 × 1080) wide high each twice, four times of area, the total pixel number amount of display device reaches more than 8,000,000.Current whole dull and stereotyped 4k2k(is called for short UD usually) TV of type gets more and more, the mode relating to the control of 4k2k screen also gets more and more, and wherein the control of a lot of screen portions needs master cpu to carry out IIC(integrated circuit (IC) bus to it) control.The content controlled mainly comprises the control action such as switching, the switching of 3D pattern, the blank screen process of UD screen end that FHD screen participates in UD screen ginseng.These control the pass key control that contents all relate to picture material display, although the failed probability of this controls is extremely low, once control unsuccessfully, just there will be the anomalies such as colored screen, blank screen, to the sense organ of user very bad.
For this low probability event, we carry out deep research, carry out great many of experiments simulation, and what find this anomaly has individual difference, and this phenomenon may appear in some UD screens, and what have then all there will not be this phenomenon all the time.The sample of phenomenon is there is for these, We conducted a large amount of analysis design mothod, the reason finally obtained is the LVDS signal of delivering to screen end when not being very stable, now just in time gives screen end by IIC signal, occurs that IIC controls failed probability and will improve this time.
Analyze the LVDS signal that UD screen is given in front end, whether LVDS signal stabilization, and showing mouth end phase-locked loop with master control IC has very large correlation, and the input signal of master control IC, if there is exception, just may cause rear end to show the situation of the phase-locked time lengthening of mouth end.Equally, the LVDS signal of this exception delivers to UD screen end, and UD screen equally also has a phase-locked action to LVDS signal, if swinging of signal, also may occur exception, thus the control flow causing UD screen end to show is abnormal.
Summary of the invention
The invention provides a kind of method improving the display of 4k2k screen reliability, the situation reducing 4k2k screen control exception occurs, and improves the reliability of screen display and the viewing experience of user.
The present invention improves the method for 4k2k screen reliability display, comprising: arrange delayed startup mark by software control to 4k2k screen; According to described delayed startup mark start-up study counting in the integrated circuit (IC) bus circulation process of primary control program, in the process of time delay counting, judge if the current state of 4k2k screen is different from arranging of preservation, then to 4k2k screen sending controling instruction, reset each state variable, remove described delayed startup mark simultaneously, otherwise according to arranging of preserving, 4k2k screen is controlled.
No matter be the LVDS signal that main control integrated circuit exports, or 4k2k screen is to the phase-locked action of LVDS, it is all the hardware module determined, for the control of television, change cannot be made, therefore can only be remedied by other means, propose a kind of indemnifying measure for present situation.By the mechanism that time delay is retransmitted, adopt suitable time-delay, again export control command, by IIC(integrated circuit (IC) bus) control probability of failure and reduce further.This delay strategy, time delay can not be oversize, can not be too short.Oversize, user can see that flower shields the phenomenon be repaired, too short, still there will be the situation of failure.After test repeatedly, the time delay obtaining 6 ~ 8 seconds is relatively suitable for.Occurring that IIC controls failed probability and has been further reduced by demonstrating after a large amount of experiments, test, in follow-up test, all not finding that IIC controls failure scenarios.
Further, the described time delay started in primary control program is counted as circulation time delay counting, and when not adopting the fixed response time directly interrupting flow model.
Preferably, described time delay is designated a flag.In the flow for displaying of TV, when IIC control is carried out to 4k2k screen, only trigger a flag bit, the flow for displaying of whole TV is not had to the impact of time delay.Simultaneously according to this flag bit, major cycle will start timing, and after reaching certain delay time, the IIC control command before resending, removes to trigger simultaneously and indicate.
Concrete, carry out the described setting to 4k2k screen and the control to primary control program by the software program in the functional control module in 4k2k screen.
Find through a large amount of tests, by method of the present invention, the situation that effectively can reduce 4k2k screen control exception occurs, and significantly improves the reliability of screen display, improve the viewing experience of user, the display quality of 4k2k screen is had further lifting.
Below in conjunction with the embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following example.Without departing from the idea case in the present invention described above, the various replacement made according to ordinary skill knowledge and customary means or change, all should comprise within the scope of the invention.
Embodiment
The present invention improves the method for 4k2k screen reliability display, comprise: by the software in the functional control module in 4k2k screen, arrange delayed startup mark to 4k2k screen, described time delay is designated a flag, makes the flow for displaying of whole TV can not be subject to the impact of time delay; According to the described delayed startup mark startup circulation time delay of 6 ~ 8 seconds counting in integrated circuit (IC) bus (IIC) circulation process of primary control program, in the process of circulation time delay counting, judge if the current state of 4k2k screen is different from arranging of preservation, then to 4k2k screen sending controling instruction, reset each state variable, remove described delayed startup mark simultaneously, otherwise according to arranging of preserving, 4k2k screen is controlled.By the mechanism that time delay is retransmitted, adopt suitable time-delay, again export control command.Occurring that IIC controls failed probability and has been further reduced by demonstrating after a large amount of experiments, test, in follow-up test, all not finding that IIC controls failure scenarios.
