The different output services frequency of life.After fundamental frequency controller 220 receives feedback signal 213, feedback signal 213 can be estimated
Frequency, and estimate the frequency of feedback signal 213 and the deviant of ideal frequency, to learn this frequency needs to be corrected how many,
Could be close to ideal frequency.Fundamental frequency controller 220 couples quartz oscillator 221, in order to produce a reference with accurate frequency
Signal.Fundamental frequency controller 220 comprises a phase-locked loop (phaselocked loop, PLL) unit 222 and a control circuit 225.
Normal pulse one during the output of quartz oscillator 221 is synchronously carried out phase-locked loop control with reference to seasonal pulse by phase-locked loop unit 222, with defeated
Go out one accurately clock signal in control circuit 225.For example, control circuit 225 can be produced according to quartz oscillator 221
Accurate clock signal carry out estimating feedback signal 213, by feedback signal 213 and accurate frequency produced by quartz oscillator 221
Rate reference signal or its frequency multiplication compare, and can learn the frequency of feedback signal 213 and the deviant of ideal frequency or deviation ratio.Lift
For example, control circuit 225 can be realized with microprocessor.
In this embodiment, fundamental frequency controller 220 according to a look-up table, can find out the frequency of the feedback signal 213 to be revised
Correcting code (correction code) corresponding to corrected value needed for rate, and corresponding for this corrected value correction signal 223 is passed
Give driver 210.It should be noted that due to the frequency of feedback signal 213 that estimates and ideal frequency deviant not necessarily
Identical with the corrected value that look-up table has row, this fundamental frequency controller 220 may be selected in look-up table closest to this deviant
Corrected value, or be divided into and being repeatedly modified so that the value finally altogether revised is acceptable less than one with the difference of this deviant
Error amount.Fundamental frequency controller 220 can by correction signal 223 depositing corresponding correcting code write driver 210
In device 212.After agitator 211 reads the correcting code in this depositor 212, you can determine the work corresponding to this correcting code
Frequency is to image process unit 240 so that image process unit 240 operates according to operating frequency to produce display control signal
224 to display device 230 is it is noted that the frequency values of the display control signal 224 and specification or user frequency values that set
Difference, will be smaller than an acceptable error offset value, to meet the specification of hardware running, and crystal oscillator that need not be plug-in
Or interior set a programmed (one-time programming, OTP) element.
Table one
| Correcting code | Corrected value |
| 000 | 0% |
| 001 | 3% |
| 010 | 6% |

Driving current respectively collocation one switch are practiced.Each group of resistance capacitance combination determines an output services frequency, or each
Current source also determines an output services frequency to fixing one group of resistance capacitance combined charging.Therefore each correcting code can represent a pair
The agitator 211 output services frequency answered.Corrected value corresponds to different frequency correction values, and frequency correction value is relevant to different
The correction relative scale value of resistance capacitor combination and former preset resistance capacitor combination, or it is relevant to different driving currents and ginseng
Examine the relative ratio of electric current.Assume that technique drift can cause the driving of the overall capacitance of chip, resistance value and current source output
The absolute value drift of electric current, but the driving current value phase for the output of different resistance, different electric capacity or different current sources
Ratio value impact between mutually is less.In this embodiment, the correction value field of look-up table is to be represented with revising ratio.Driver
After 210 receive the correction signal 223 that fundamental frequency controller 220 transmits, the agitator 211 within driver 210 can choose this
Resistance capacitor combination is used in the corresponding correction of correction signal 223, or chooses corresponding current source, and one group of resistance capacitance is charged
Afterwards, produce an operating frequency to image process unit 240, produce calibrated display control signal then according to this operating frequency
224 in display device 230 so that deviant between the frequency values of display control signal 224 and an ideal frequency is less than one makes a reservation for
Error amount.
In this embodiment, driver 210 does not require the use of a programmed (one time programming, OTP)
Technique, and without carrying out chip pin survey (chip probing test, CP test) and OTP sequencing to correct agitator 211
The frequency of output, reaches the effect saving chip manufacturing time and cost.The action of the correction feedback signal 213 of the present embodiment,
Can implement when portable multimedia device is started shooting, user also can according to use demand, or, dynamically
(dynamically) modified ideal frequency value, it is preferred that it is dynamic to increase execution correction in the User's Interface of control device 200
The option made.In this embodiment, after control device 200 receives the instruction of execution corrective action, can be in display device 230
In (vertical blanking period) during vertical blank, the action of execution aforesaid correction feedback signal 213, to adjust
Whole frame display frequency to user demand value, consequently, it is possible to the correction of frequency does not interfere with the display of normal pictures.Should note
Anticipate and arrive, the action of the above-mentioned execution correction of the present embodiment can perform more than once, for example, deviant can be divided into multiple school
Just, or even step by step revise side-play amount, according to the frequency switching operation of user, dynamically by the frequency correction of feedback signal
To the ideal value wanted, further increase the DE of product use.

Mark) signal, the signal of voltage-controlled oscillator output, the signal of current control oscillator output, common electric voltage (common
Voltage, Vcom) signal, horizontal-drive signal or vertical synchronizing signal.Step 320 is to be estimated back using fundamental frequency controller
The frequency of feedback signal and the deviant of ideal frequency.For example, it is possible to use enumerator is in the adjacent rising edge of feedback signal
Count to the seasonal pulse of several feedback signals, and estimate its frequency values and its deviant with ideal frequency.Step 330 is to utilize fundamental frequency
Controller produces a correction signal to driver according to this deviant.For example, fundamental frequency controller can utilize a look-up table
Find out the corresponding correcting code of this deviant, and the correction signal representing this correcting code is sent to driver, by this correcting code
It is stored in the depositor (register) in driver.It should be noted that the frequency of feedback signal due to estimating and preferable frequency
The deviant of rate not necessarily has the corrected value of row identical with look-up table, and fundamental frequency controller may be selected closest in look-up table being somebody's turn to do
One corrected value of deviant, or it is divided into multiple correction so that the difference of the last value altogether revised and this deviant is less than predetermined
Error amount.Step 340 is to produce the corresponding operating frequency of correction signal using this driver.For example, in driver
Agitator can read the corresponding correcting code of this correction signal from internal register, and each correcting code represents different output services respectively
Frequency.Step 350 is to produce display control signal using this driver according to operating frequency.Last flow process ends at step 360.
According to above step, control method flow process of execution, or it is divided into multiple progressively correction so that the last display control producing is believed
Number frequency values and ideal frequency value difference, a predictive error value will be smaller than.In addition, in another embodiment, user can
According to use demand, change ideal frequency value at any time, it is preferred that after having changed every time, (vertical during vertical blank
