[0044] Reference Figure 6 to Figure 8 In the first example of the invention, the method of driving the plasma display panel is described. Figure 6 It is an explanatory diagram of driving waveforms in one frame in the driving method of the plasma display panel of the present invention. Figure 7 Yes Figure 6 An enlarged view of part A in the middle.
[0045] Figure 8 It is a diagram of the driving method of the plasma display panel of the present invention. The reset pulses are applied in order within the domain at a predetermined time.
[0046] Such as Figure 6 As shown, when the afterimage occurs in the first frame and the second frame consecutive to the first frame, the second frame can apply a reset pulse in at least any subfield and has the function of adjustment. For example: using the first frame On cell to apply 12 previous reset pulses in 12 subfields, the afterimage pattern will occur when the second frame of the next frame is Off cell. Here, the second frame may be a plural frame.
[0047] Therefore, when the first frame of the On cell is converted to the second frame of the Off cell, the pulse is adjusted from the last subfield of the second frame.
[0048] Such as Figure 7 As shown, in the first example of the invention, the waveform of the reset pulse can be applied to at least any one of the subfields in the second frame described above.
[0049] The above-mentioned second frame can be adjusted by applying the set up pulse applied in the set up section of the reset section of the reset pulse sequentially in at least any one subfield. Here, in the second frame, the reset pulse can be sequentially applied in at least any one subfield. The reset period in the reset period is characterized by a rectangular wave.
[0050] In addition, the voltage value of the above-mentioned rectangular wave is characteristic of the voltage value (Vs) of the sustain pulse. In the second frame, the reset pulse can be applied in at least any subfield. The voltage of the set up pulse applied in the set up section of the reset section is the ground level (GND) voltage value.
[0051] The gray scale difference of the reset pulse of the present invention is about 0cd/m per pulse 2 , The original reset pulse gray scale difference is 0.1cd/m 2 In this way, the afterimage level produced during Off cell conversion can be greatly reduced.
[0052] Here, if the reset pulse of the present invention is used blindly in all subfields, erroneous discharge will occur. In order to improve this situation, it is as Figure 8 As shown, the second frame is characterized by being able to apply reset pulses sequentially in at least any subfield.
[0053] For example, the subfields of one frame are composed of 12 subfields. When the first frame of On cell switches to the next frame of Off cell, an improved reset pulse is applied in the reset interval of the last subfield of the next frame.
[0054] The next procedure is, if the next frame of the Off cell frame is also Off cell, then from the last subfield, an improved reset pulse is applied in the reverse direction of the reset interval of the two subfields. Then, press the Off cell frame
[0055] The number of reset pulses improved by the present invention in the reverse sequence of repeated counting subfields also increases.
[0056] On the contrary, if the Off cell frame transitions to the next frame On cell, the original reset pulse must be reapplied in all subfields.
[0057] Similarly, applying the improved reset pulse in the aforementioned manner should prevent the reset pulse of the present invention from being arbitrarily applied to all subfields to prevent false discharge, and at the same time, the dark afterimage can be quickly eliminated within a certain period of time.
[0058] Although the examples of the present invention are described with reference to the above drawings, those skilled in the art can operate according to their own understanding of how to implement other specific forms without changing the technical idea of the present invention. Therefore, the above technical examples should be understood as only demonstrative in all aspects, rather than static. All changes or morphological changes equivalent to the present invention are included in the scope of the present invention.
