Embodiment
Please refer to Fig. 1, Fig. 1 is the schematic diagram of the display device 100 of one embodiment of the invention.Display device 100 comprises system end 110, drives chip 120 and display panel 130.Drive chip 120 to be coupled to system end 110 and display panel 130.Drive chip 120 to comprise and show data receiver interface 121, error detector 122, display controller 123 and storer 124.Show that data receiver interface 121 is coupled to the demonstration data crossfire DSI that system end 110 is transmitted with receiving system end 110,122 of error detectors are coupled to and show that data receiver interface 121 detection display data receiver interface 121 receive the one or more error messages that produce in the process that shows data crossfire DSI.It should be noted that, the generation reason of above-mentioned error message, may come from the existing interference phenomenon of environment of living in, system end 110 of display device 100 and show the impedance mismatch of the transfer wire between data receiver interface 121 and/or be to show that the factors such as the data rate of data crossfire DSI is too fast cause.
Error detector 122 is after acquisition shows the one or more error messages that produce in the process of data receiver interface 121 reception demonstration data crossfire DSI, can be to system end 110 its detected error messages of passback, wherein, in the present embodiment, error detector 122 can produce misdata crossfire ERRS for error message, and by the passage of non-high-speed transfer, misdata crossfire ERRS is sent to system end 110 for analysis.
Noticeable, for avoiding increasing the pin number that drives chip 120, in the present embodiment, error detector 122 can be by driving in the multiple output pins in chip 120, and the idle pin not being used to carries out the transmission action of misdata crossfire ERRS.Wherein, idle pin can be for example backlight control signal pin LEDPWM or tear effect (tearing effect, TE) signal pins TE.
In addition, in the transmission action of carrying out the misdata crossfire ERRS in error detector 122 and system end 110, can be undertaken by the transmission mode of any serial line interface, for example inter-integrated circuit (Inter-Integrated Circuit, 12C) interface or Serial Peripheral Interface (SPI) (Serial Peripheral Interface, SPI).
123 of display controllers couple and show data receiver interface 121, and receive by the demonstration data that show that data receiver interface 121 spreads out of, and display controller 123 also produces and drives signal DOUT to drive display panel 130 according to received demonstration data.124 of storeies are coupled to display controller 123, to provide display controller 123 to be used as data buffer.At this, storer 124 can be used as picture frame buffer zone (frame buffer) and/or is line buffer zone (line buffer) according to the demand of display controller 123, and about how using storer to become picture frame buffer zone and/or be that the implementation detail of line buffer zone is known the known technology of the knowledgeable conventionally as this area tool taking design, below do not repeat for this reason.
Below please refer to Fig. 2, Fig. 2 illustrates the oscillogram of the misdata crossfire ERRS of the embodiment of the present invention.Wherein, misdata crossfire ERRS comprises wrong start signal ES, misdata signal ER1 and ER2 and wrong end signal EE successively.Wherein, the quantity of misdata signal ER1 shown in Fig. 2 and ER2 is an example, in same misdata crossfire ERRS, in wrong start signal ES and wrong end signal EE, can comprise one or more misdata crossfires, its quantity is restriction not.
In addition; in misdata crossfire ERRS, can also comprise wrong start guard signal GOS; wrong start guard signal GOS is placed between the wrong start signal ES and misdata signal ER1 in misdata crossfire ERRS, makes two signals can not produce phase mutual interference in order to separate wrong start signal ES with misdata signal ER1.In addition, between each misdata signal ER1 and ER2, also can assign bit boundary signal BB, to separate each misdata signal ER1 and ER2.In other words,, in a misdata crossfire ERRS, the quantity of bit boundary signal BB can be that the sum of misdata signal subtracts 1.
In the present embodiment, wrong start signal ES is made up of multiple pulse, in order to apprizing system end 110, system end 110 is carried out and is received follow-up misdata signal ER1 and the preparation of ER2.Wrong start guard signal GOS can be the pulse signal that continues high level, effectively to separate wrong start signal ES and follow-up misdata signal ER1.At this, wrong start guard signal GOS non-essential signal, under the good state of signal transmitting quality, wrong start guard signal GOS be can be omitted no.Bit boundary signal BB continues the pulse signal of high level, and in order to misdata signal ER1 and the ER2 of effective space between adjacent, certainly, under the good state of signal transmitting quality, also non-essential signal of bit boundary signal BB.
Mistake end signal EE can be also the signal that continues high level, and finishes in order to the transmission action of informing misdata crossfire ERRS.For the difference between clear and definite definition error end signal EE and bit boundary signal BB and wrong start guard signal GOS, can make system end 110 know that its received lasting high level signal is wrong end signal EE or the bit boundary signal BB that is used as the time interval (or wrong start guard signal GOS) by defining different lasting high level times.Certainly, mistake end signal EE, bit boundary signal BB and wrong start guard signal GOS also can utilize different waveforms to present, and not must identically with the present embodiment realize in the mode that continues high level.
