The present invention is by being just arranged to the dynamic variable that can select by conversion multiple.Therefore, effectively solve the not modifiable problem of conversion multiple, optimized control parameter regulative mode, realized better experience effect.For further illustrating the present invention, provide the following example:
Embodiment mono-
Please refer to Fig. 1, is a kind of process flow diagram of controlling parameter adjusting method provided by the invention.The method is applied to display device, comprises step:
101, receive and regulate parameter instruction, and regulate parameter M according to regulating parameter instruction to obtain;
In the present embodiment, regulating parameter instruction can be the electric signal sending by operation related key.Now, display device to meeting by the electric signal receiving amplify, filtering produces a triggering level after processing, this triggering level (for example can trigger main control chip, be generally the CPU in display device or there is the MCU of cpu function) remove to search default adjusting parameter library corresponding in internal memory, thus obtain adjusting parameter M corresponding in this electric signal.Hold intelligiblely, it is the Digital ID that we see conventionally on TV or the control strip of mobile phone that so-called adjusting parameter also can be understood as; And these Digital IDs are people, be to be set in the internal memory of display device, when carrying out the operation of associated adjustment, this current adjusting numerical value can be transferred by main control chip and be shown by display unit from internal memory; Like this, when regulating, just can show in real time the numerical value of current adjusting.

In a preferred embodiment, the present invention is for the setting of conversion multiple K, can before product export, arrange and pre-stored in internal memory, also can be by user according to the actual requirements, and self-defined setting.Due to like this, therefore design concept of the present invention can meet dissimilar control parameter and regulates, and has practicality.
104, the operational module that control display device is corresponding is according to controlling parameter N work;
Wherein operational module is generally and controls the adjustable module of parameter, and as backlight control module or volume control module etc., their output all can be sent steering order by main control chip and be regulated.And in steering order, just comprising above-mentioned control parameter N, and operational module receives after steering order, and the control parameter N in just can instruction is set to Set For Current parameter, then according to this parameter, carries out work.
The present invention, by conversion multiple is arranged to the dynamic variable that can select, therefore, has effectively solved the not modifiable problem of conversion multiple, has optimized control parameter regulative mode, has realized better experience effect.
Embodiment bis-
In the present embodiment, with the example that is adjusted to backlight, the present invention is described in more details.
Conventionally smart mobile phone or the display screen of intelligent television is LCDs, the namely abbreviation of LCD(Liquid Crystal Display) LCDs.As shown in Figure 2, liquid crystal panel mainly comprises array base palte 24 and the colored filter 23 being oppositely arranged to its displaying principle, and array base palte and colored filter and liquid crystal layer 25 are also provided with polaroid 21 and lower polaroid 22 in the both sides of liquid crystal panel.In prior art, color filter 24 is normally comprised of Red lightscreening plate, green color filter and blue color filter, and its different combination can produce the light of different colours; Because liquid crystal panel itself is not luminous, therefore need back light to provide light source for it.Conventionally on array base palte 24, be provided with the image element circuit that matrix is arranged, by image element circuit, control the deflection of liquid crystal molecule in liquid crystal layer 25, and then control the luminous flux that back light incides liquid crystal panel.Therefore, if want the brightness of adjustable liquid crystal display display screen to set about from adjusting luminous flux.

| 0≤M≤23 | 3 | 26≤N≤98 |
| 24≤M≤75 | 2 | 99≤N≤201 |
| 76≤M≤100 | 1 | 202≤N≤226 |
Table 2-1
Wherein, when the scope of M 0～23, because brightness ratio backlight is darker, be not suitable with eye recognition, thus in the present embodiment, this scope internal conversion multiple K is arranged more greatly 3, be equivalent to the every increase by 1 of M, corresponding N will increase by 3, causes the adjustment process within the scope of this can be very fast; When the scope of M 24～75, because brightness backlight is relatively also darker, although can pass through eye recognition, but recognition effect is undesirable, so in the present embodiment, this scope internal conversion multiple K is set to 2, is equivalent to the every increase by 1 of M, corresponding N will increase by 2, causes the adjustment process within the scope of this also can be relatively very fast; When the scope of M 76～100, because brightness backlight has arrived the normal range of eye recognition, in order to make the adjusting within the scope of this can be more careful and accurate, in the present embodiment, this scope internal conversion multiple K is set to 1, is equivalent to the every increase by 1 of M, and corresponding N also increases by 1, with this, brightness in OK range is changed to segmentation, so that be adjusted to a best brightness value.Therefore, the fixedly restriction with respect to prior art to conversion multiple, the invention provides conversion multiple K corresponding to a kind of piecewise interval with regulating parameter, thus optimal control parameter adjustment process, and practicality is enhanced.
Embodiment tri-
Design based on identical, the present invention also provides a kind of control parameter adjustment control, is applied to display device, and as shown in Figure 3, this device comprises:
Parameter is divided module 32, and adjusting parameter area is carried out to subsection setup, every section of conversion multiple K that correspondence is different,
Parameter modular converter 33, according to conversion multiple K corresponding to described adjusting parameter M place piecewise interval, is converted to corresponding control parameter N by described adjusting parameter M;
Parameter arranges module 34, for controlling operational module that display device is corresponding according to controlling parameter N work.
In the present embodiment, regulating parameter instruction is the electric signal sending by operation related key.Now, display device can amplify the electric signal receiving, filtering produces a triggering level after processing, this triggering level can trigger main control chip and remove to search default adjusting parameter library corresponding in internal memory, thereby parameter acquisition module 31 is obtained adjusting parameter M corresponding in this electric signal, parameter is divided module 32 and can will be regulated according to the actual requirements parameter to divide different intervals, and each interval corresponding different conversion multiple K; Parameter modular converter 33 is received adjusting parameter M, and parameter modular converter 33 can be converted to control parameter N by adjusting parameter M according to conversion multiple K.After converting, parameter modular converter 33 can send to parameter that module 34 is set control parameter N.Parameter arranges module 34 and according to controlling parameter N, removes to control operational module corresponding on this display device and carry out work according to controlling parameter N again.What in the present invention, operational module refered in particular to is backlight control module and volume control module.Therefore, the fixedly restriction with respect to prior art to backlight illumination and volume adjusting, the invention provides conversion multiple K corresponding to a kind of piecewise interval with regulating parameter, thus optimal control parameter adjustment process, and practicality is enhanced.
Embodiment tetra-
In the present embodiment, take volume adjusting as example, the present invention is described in more details.
Volume claims again loudness, loudness of a sound, refers to that people's ear is to the heard strong and weak subjective feeling of sound size, the amplitude size that its objective evaluation yardstick is sound.The pressure that this impression produces while being derived from object vibration, i.e. acoustic pressure.Object vibration, by different media, conducts its vibrational energy.People, for the detecting impedence of sound being changed into the index that can monitor, are just divided into acoustic pressure " level "---sound pressure level, to can objectively represent the power of sound, its unit is called " decibel " (dB).The standard setting of 0 decibel is that the minimum sound that can hear according to the normal people of hearing is determined.10 decibels of every increases equal intensity and increase to 10 times, increase by 20 decibels and increase to 100 times, and 30 decibels increase to 1000 times.Concrete classification is as shown in table 4-1.
Table 4-1
Therefore, suppose that 30 decibels is bass area below, 30～60 decibels is middle register, and 60～120 decibels is treble.More than common 105 decibels is noise, does not do to consider.The scope of supposing volume adjusting parameter M is 0～60, if volume will be adjusted to 50 decibels from 10 decibels, in the present embodiment, can be by operation related key, as " volume adds " button sends the electric signal that comprises regulating command.Now, display device can amplify the electric signal receiving, filtering produces a triggering level after processing, this triggering level can trigger main control chip control parameter acquisition module 41 and remove to search default adjusting parameter library corresponding to volume in internal memory, thereby obtains adjusting parameter (as 11) corresponding in this electric signal; Parameter is divided module 42 and in advance adjusting parameter region is divided, and each interval corresponding different conversion multiple K; When parameter modular converter 43 is received adjusting parameter (as 11), parameter modular converter 43 can will regulate parameter (as 11) to be converted to corresponding control parameter according to conversion multiple K.For volume control module, the pass of conversion multiple K is, K
3> K
1> K
2, suppose K
1=2, K
2=1, K
3=3.The transformational relation of actual volume and control parameter N is as shown in table 4-2.
| Regulate parameter M | Conversion multiple K | Control parameter N | Decibel |
| 0≤M＜15 | 2 | 0≤N＜30 | 0≤N＜30 |
| 15≤M＜45 | 1 | 30≤N≤60 | 30≤N≤60 |
| 45≤M≤60 | 3 | 60≤N≤105 | 60≤N≤105 |
Table 4-2
As seen from the above table, transformation result is N=22.Then parameter modular converter 43 can send to parameter that module 44 is set control parameter N=22.Parameter arranges module 44 and according to controlling parameter N=22, goes to control volume control module corresponding on this display device 45 work again, and volume control module 45 is play the corresponding volume of 22 decibels by the decoded audio-source of audio processing modules 46 according to controlling parameter N=22 control loudspeaker 47 again.By internal memory, preserved again the control parameter of current volume.
By that analogy, when regulating parameter M=15, corresponding control parameter N=30, corresponding 30 decibels, regulating during this period control parameter corresponding to parameter is 2 times of variations, therefore regulates efficiency to improve, and also can obviously feel the variation of sound; When regulating parameter M=16, corresponding control parameter N=31,31 decibels of correspondences, now the conversion multiple K=1 of M and N, until regulate corresponding decibel during parameter M=45, be 30～60(middle register) adjustment process can become thinner and make peace accurately so that choose suitable volume.Hence one can see that, and the present invention can just be arranged to the dynamic variable that can select by conversion multiple.Therefore, effectively solve the not modifiable problem of conversion multiple, optimized control parameter regulative mode, realized better experience effect.
Comprehensive above-described embodiment, can find out, the present invention has effectively solved the not modifiable problem of conversion multiple, has optimized control parameter regulative mode, has realized better experience effect.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
