Fig. 2 provides a kind of structural representation of display terminal for the embodiment of the present invention.
Embodiment
In the prior art, the mainboard IC of display terminal can carry out Video processing after each information source channel receives signal,
It is converted into LVDS signals or VB1 signals is sent to timer/counter control register (Timer Control
Register, TCON) end；The signal that i.e. whichever information source is come in, it is required for carrying out frequency conversion by main IC, is encoded into
LVDS signals (clock signal, frequency are 74.25MHZ) or VB1 signals (clock signal, frequency are 3.2GHZ).Turn in frequency
When changing, the pll clock register of main IC interior liabilities Video coding, appropriate frequency shift (FS) is had, it is therefore intended that solve coding
When there is the problem of video frame losing；So in test LVDS clock frequencies generally in the range of 74.25MHZ+-0.5%；And
The frequency of VB1 signals equally also has corresponding frequency departure scope (+- 0.5%, 30KHZ)；
Mainboard IC and TCON shakes hands, mainboard end is synchronous clock first when transmission signal is shaken hands for VB1 signals
Signal is sent to receiving terminal (TCON)；TCON can feed back HOTPLUG signals and LOCK signal to mainboard when locking, and now shake hands into
Work(；Mainboard end just starts normally to send vision signal after detecting HOTPLUG signals and LOCK signal；
When carrying out handshake operation, it is desirable to which the clock recovered from VB1 signals can not have compared with macromutation (VB1 agreements
Claimed range requirement is+- 0.5%, 30KHZ), if it exceeds this change frequency, then it is wrong that can be considered as signal；Now connect
Receiving end would not feed back HOTPLUG signals and LOCK signal to mainboard；Because when mainboard carries out source signal conversion, it is appropriate to have
Frequency shift (FS), so receiving terminal has been over (+- 0.5%, 30KHZ) in the equivalent frequency scope tested out；And reach
(+- 0.8%, 2MHZ)；So causing normally to shake hands, the abnormal problems such as display screen flower screen are caused.
In view of the above-mentioned problems, the embodiment of the present invention provides a kind of data processing method, this method is applied to a display terminal
In, the display terminal is used for output display content including a display output unit, and when meeting the first preparatory condition, the display is whole
Mainboard in end carries out handshake operation with time controller to be included：
The seizure frequency setting of phase-locked loop pll is default reference frequency by mainboard；
Tranmitting data register synchronizing signal gives time controller TCON, is receiving the feedback letter based on the clock sync signal
After breath, Frequency Locking is realized based on the default reference frequency and the TCON.
In method provided by the invention, when mainboard is shaken hands with time controller, mainboard can be by the seizure of phase-locked loop pll
Frequency is adjusted to a default reference frequency, then retransmits clock sync signal to time controller, in this case
The equivalent frequency scope that the clock sync signal that clock controller receives is tested out can just meet the identification need received
Ask.So in this embodiment, no matter mainboard IC when frequency conversion by the frequency conversion of source signal into what kind of
Frequency, the handshake operation of mainboard and clock controller can be realized by way of conversion frequency by this mode.Avoid
The problem of Hua Ping etc. is abnormal.
