Specific embodiment
The principles and features of the present invention are described below, and the given examples are served only to explain the present invention, is not intended to limit
Determine the scope of the present invention.
As shown in Fig. 2, the present embodiment is related to a kind of waveform adjustment method for shortening dark red Bai Sanse refresh time, debugging
When driving voltage waveform, it is equipped with balance of voltage region (Group1), blinking region (Group2, Group4, Group6, Group8)
With display area (Group3, Group5, Group7, Group9, Group10), blinking region is in be alternately distributed with display area,
The following steps are included:
Step 1: in balance of voltage region, the charged particle voltage opposite with its included polarity of voltage is given to neutralize electricity
Pressure；
Step 2: in blinking region, first giving high voltage drive to charged particle, shows that picture is leaned on by black picture at this time
Closely, then low voltage drive is given, shows that picture is close to white picture at this time, then given high voltage drive again, finally give
Low voltage drive terminates after circulation is multiple；
Step 3: the white waveform in display area is given high voltage drive and is given at black picture, black and red-colored waveform
Low voltage drive is given into white picture, terminates display area；
Step 4: when blinking region and display area alternate cycles repeatedly enter back into display area, white waveform is to give
Low voltage drive, black wave are high voltage drives, and red-colored waveform is first to give low voltage drive to give the driving of+6V voltage again；
Step 5: after the voltage cycle given to the display area in step 4 is multiple, red-colored waveform will be shown
Come, adjusts white, black and red charged particle in the frame number of display area, until reaching display effect.
The function in balance of voltage region is mainly display area provides how many positive voltage, and balance of voltage region just provides how many
Negative voltage or television area provide how many negative voltage, and balance of voltage region just provides how many positive voltage, guarantee generating positive and negative voltage phase
Deng.
Blinking region is made of high-low voltage or low high voltage cycle, forms black and white screen or white black picture cycle flashing
Display.
Preferably, the duration of the single high voltage drive in step 2 and single low voltage drive is 40ms.
Preferably, the voltage cycle number in blinking region is five times.
Preferably, the voltage cycle number in step 4 in display area is three times.
Preferably, the number of the voltage cycle in final display area is four times.It can make in final display area in this way
Red-colored waveform is quickly shown, so as to shorten the refresh time of three color waveforms.
Preferably, high voltage is+15V, and low-voltage is -15V.
The debud mode of this programme, which mainly replace with blinking region with display area to cooperate to debug, to be formed, when debugging,
The adjustment method of the blinking region Group2 is first driving+15V, the high voltage of 40ms, shows that picture is close to black picture at this time,
- 15V is driven again, and the low-voltage of 40ms shows that picture is close to white picture at this time, then drives the high voltage of 40ms, then drive
The low-voltage of 40ms terminates blinking region after recycling five times, and the practical refresh time in the blinking region Group2 at this time is 800ms.
Display area Group3 is immediately entered after the blinking region Group2, the waveform of white displays driving is the height electricity for providing+15V
At black picture, the drive waveforms of black and red display are the low voltage drives of -15V provided into white picture for pressure driving,
Because the voltage when terminating the blinking region Group2 is that low-voltage needs to provide after entering the display area Group3
High voltage keeps generating positive and negative voltage to balance, and the white waveform in this way in display area is whiter.Terminate the display area Group3
Afterwards, the blinking region Group4 and the display area Group5 are entered back into, is so alternately entered back into until terminating the blinking region Group8
The display area Group9, in the display area Group9, the waveform of white displays driving is to the low voltage drive of -15V, black
The drive waveforms of display are the high voltage drives of+15V, the waveform of red display driving be first to after the low voltage drive of -15V again
It is driven at once to the voltage of+6V, it is therefore an objective to red driving be made to show that the voltage in the display area Group9 need to recycle three
It is secondary, subsequently into the display area Group10, the voltage and the voltage phase in the display area Gruop9 that are provided in display area
Together, after voltage cycle four times, so that the red-colored waveform in the display area Group10 is shown, then using debugging, so that
The display effect that dark red white three kinds of waveforms have reached, red-colored waveform have just been revealed in the display area Group9,
But due to the limitation of cycle-index, color is not reached requirement, so being further added by one group behind the display area Group9
Voltage identical with the display area Group9 is given, and recycle four in the display area Group10 in the display area Group10
Secondary, finally in the display area Group10, dark red Bai Sanse waveform is fully displayed out.
As shown in figure 3, Ghosting represents ghost in figure, after three color waveforms are revealed, by optical tester
Test obtains the data such as figure, and You Tuzhong optical value is it is found that the three color waveforms shown have reached the requirement of color.
Above description has shown and described several preferred embodiments of the invention, but it has been observed that it should be understood that the present invention simultaneously
It is not limited to form disclosed herein, should not be regarded as an exclusion of other examples, and can be used for various other combinations, repair
Change and environment, and can within that scope of the inventive concept describe herein, by the above teachings or related fields of technology or knowledge into
Row change.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then it all should be in the present invention
