Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
In LED control system, display frequency, or the display frequency being called complete GTG, correspond to the complete GTG display cycle, be the frequency corresponding to displaying time of complete GTG, its highest switching response frequency with whole control system, LED luma data numerical digit are relevant.Wherein, the complete GTG display cycle is that each numerical value of luma data all experiences full-time total length required for clear and definite corresponding output procedure.For the ignition frequency of some significance bits, being that LED corresponding to certain of luma data is per second lights number of times.
One embodiment of the present of invention are, a kind of dynamic self-adapting improves the method for display frequency, it comprises the following steps: using most significant digit be not one data to be displayed move to left C position as amendment after display data show, the most significant digit making amendment show data is afterwards one, and arranges C power/mono-that its output enable signal time is 2 of former display data corresponding output enable signal integrity time.Such as, the numerical value of C is pre-seted.Such as, C be set to 1,2,3 ... 32768.Preferably, according to the figure place N of described data to be displayed, pre-set the numerical value of C.Such as, N=256, C=128; And for example, N=256, C=3; And for example, N=128, C=15; And for example, N=65536, C=3000; And for example, N=16, C=2; And for example, N=8, C=3 etc.; The present invention and each embodiment thereof are not restricted this.
Wherein, the switching frequency of LED, i.e. physics refreshing frequency, comprising: the high gray physics refreshing frequency of high bit in display data, compared with the low GTG physics refreshing frequency of low level in display data.Complete GTG refreshing frequency, refers to that LED that complete GTG is corresponding is per second and lights number of times.That is, physics refreshing frequency be improved, because the number of times of unit interval is exactly frequency, therefore only needs the number of times increasing effective display translation, good display effect can be reached.
In the various embodiments described above, after amendment, the output enable signal time of display data is corresponding respectively shortens to 1/2,1/4,1/8 of script etc.Due to the factor of unit interval, be equal to display frequency, the frequency namely corresponding to the unit interval.And for example, the displaying time below the unit interval, unique difference is that enable signal shortens in various degree.Specifically, realizing unit interval following GTG realizing method is: by the use to enable signal, realizes unit interval below brightness and exports, namely, effective display translation is in valid data serial transfer and after successfully loading, under the effective condition of OE signal, can produces; Therefore having the output realizing the unit interval below may.Thus, make to be shorter than a display translation time effective time of output enable signal, when needs promote physics refreshing frequency, namely strengthen shooting effect, just can increase unit interval quantity, namely increase the number of switches in the unit interval.
Be applied to the various embodiments described above, an example keeps the figure place N of described data to be displayed, as the figure place of display data after amendment; Wherein, the figure place N of the described data to be displayed of described maintenance, is included in described data to be displayed and moves to left behind C position, the C position vacated on the right side of described data to be displayed, to fill at random, is all filled to 1 or be all filled to 0.Such as, after data to be displayed moves to left C position, the C position vacated on right side can be arranged arbitrarily, fill at random, be all filled to 1 or be all filled to 0, makes amended display data remain N position, i.e. the figure place of original data to be displayed.
