Below, lift preferred embodiment, and conjunction with figs. is described in detail as follows.
Fig. 3 is in the embodiments of the invention, the synoptic diagram of plasma display system.
As shown in Figure 3, the plasma display system in the embodiment of the invention comprises: digital drive panel 310, turntable driving panel 320 keeps driving panel 330 and control panel 340.
Digital drive panel 310 is during locating, to the negative position pulse that adds of addressing electrode (not shown).
Turntable driving panel 320 is at reseting period, to the negative reset pulse that adds of scan electrode (not shown); The negative scanning impulse that adds during locating; Negative adding, kept pulse during keeping.
Keep driving panel 330 during keeping, negative adding, kept pulse.
Control panel 340 drives the negative control figure that adds of panel and drives panel 310 to each, turntable driving panel 320 and keep and drive the data of panel 330 to the negative pulse that adds of each electrode.Though not shown among Fig. 3, above-mentioned driving panel is positioned at the rear end of Plasmia indicating panel, and above-mentioned driving panel links to each other with electrode respectively.
Again, in the plasma display system in the embodiment of the invention, control panel 340 has at least more than one signal transmission unit 360, and digital drive panel 310 has at least more than one digital signal acceptance division 370.As shown in Figure 3, the digital signal sending part 360 of control panel 340 is formed by one; Digital drive panel 310 is made up of four parts, and possesses digital signal acceptance division 370 respectively in the digital drive panel 310 of each part.Digital drive panel 310 is divided into a plurality of, thereby the size of digital drive panel 310 will reduce.This is because the digital signal acceptance division 370 that is installed on each digital drive panel 310 directly is connected with the signal transmission unit 360 of control panel 340.Therefore, need not connect each digital drive panel 310, the coupling part of each digital drive panel 310 is deleted.Therefore, the size of digital drive panel 310 will reduce the coupling part size.
The digital signal sending part 360 of control panel 340 is connected by cable 350 with the digital signal acceptance division 370 of digital drive panel 310, and by cable 350, data will transfer to signal receiving part 370 from signal transmission unit 360.The transmission quantity of the data by signal transmission unit 360 transmission is not to be certain, but different along with the image of Plasmia indicating panel.For example, moving image is than rest image, the picture that brighter picture is darker, and the transmission quantity of its data is more, and above-mentioned data transfer to signal receiving part 370 by signal transmission unit 360.
The volume of transmitted data of digital signal sending part 360 transmission by control panel 340 is different along with image.At this moment, be transferred to the signal receiving part 370 of same digital drive panel 310 once by the mass data transmission quantity of signal transmission unit 360 transmission, then delay will appear in the transmission of data.Therefore, in order to prevent the delay of data transmission, digital drive panel 310 should possess at least more than one digital signal acceptance division 370.Even data transmission by same signal transmission unit transmission, receives with a plurality of signal receiving parts 370 during as if reception, then the transmission of data is carried out dispersedly.Therefore, data transmission is more smooth and easy, thereby can prevent the delay of data transmission.
Fig. 4 is in an alternative embodiment of the invention, the synoptic diagram of plasma display system.
As shown in Figure 4,, in Fig. 3, had illustratedly, omitted to mention at this for the identical explanation of the plasma display system in the another embodiment of the present invention.
In the plasma display system in the another embodiment of the present invention, control panel 340 has at least more than one signal transmission unit 360, and digital drive panel 310 has at least more than one digital signal acceptance division 370.The digital signal sending part 360 of control panel 340 is formed by one; Digital drive panel 310 is also formed by one.But the digital signal acceptance division 370 of digital drive panel 310 is made up of a plurality of.Digital drive panel 310 is formed by one, and then the size of digital drive panel 310 will reduce.This is because the size that is installed in the digital signal acceptance division 370 on each digital drive panel 310 is littler than the size of each digital drive panel 310 direct cable segment connector that link to each other.The size of digital drive panel 310 will reduce above-mentioned cable segment connector and cable size.Again, digital drive panel 310 is formed by one, so the manufacturing of Plasmia indicating panel is simple, and can shorten manufacturing time.
For the identical explanation of digital signal sending part 360 with the digital signal acceptance division 370 of digital drive panel 310 of control panel 340, in Fig. 3, had illustratedly, omit to mention at this.
Fig. 5 is among another embodiment again of the present invention, the synoptic diagram of plasma display system.
As shown in Figure 5,, in Fig. 3, had illustratedly, omitted to mention at this for the present invention's identical explanation of the plasma display system among another embodiment again.
In the plasma display system among another embodiment, control panel 340 has at least more than one signal transmission unit 360 again in the present invention, and digital drive panel 310 has at least more than one digital signal acceptance division 370.The digital signal sending part 360 of control panel 340 forms mutually accordingly with the digital signal acceptance division 370 of digital drive panel 310.Therefore, if the digital signal sending part 360 of control panel 340 is formed by a plurality of, then the digital signal acceptance division 370 of digital drive panel 310 is formed by the quantity identical with the quantity of the digital signal sending part 360 of control panel 340.Illustrating digital drive panel 310 situation identical with the quantity of digital signal acceptance division 370 among Fig. 5, so is not to be subject to this.Signal transmission unit 360 quantity of data should be lacked than the quantity of digital signal acceptance division 370.This be because: if the quantity of digital signal sending part 360 is more than the quantity of digital signal acceptance division 370, and when then carrying out data transmission simultaneously in digital signal sending part 360, the probability that data delay takes place in digital signal acceptance division 370 is higher.Again, though form by one with digital drive panel 310 or by a plurality of form irrelevant,, the quantity of digital drive panel 310 should be identical with the quantity of digital signal acceptance division 370 or few.This be because: if the quantity of digital drive panel 310 is more than the quantity of digital signal acceptance division 370, then the digital drive panel 310 that possesses digital signal acceptance division 370 to be connected with the digital drive panel 310 that does not possess, carry out data transmission.Therefore, have only the quantity of digital drive panel 310 identical or few, the coupling part that just can delete 310 of digital drive panels, thereby the manufacturing unit price of minimizing Plasmia indicating panel with the quantity of digital signal acceptance division 370.
The digital signal sending part 360 of control panel 340 forms mutually accordingly with the digital signal acceptance division 370 of digital drive panel 310, when then transmitting data, will be distributed to each several part, so transmission speed quickening, the not delay phenomenon that can transmit.Therefore, can carry out the high-speed driving of Plasmia indicating panel.So far, we are that one situation is illustrated to digital drive panel 310.When digital drive panel 310 was one, digital drive panel 310 was as long as form on the top of control panel 340 or a part in the bottom.Following Fig. 6 is in the embodiments of the invention, the synoptic diagram of the plasma display system of process repacking.As shown in Figure 6, form digital drive panel 310 respectively, form turntable driving panel 320 respectively and keep driving panel 330 on the left side and the right side of control panel 340 in the top and the bottom of control panel 340.
Digital drive panel 310 is positioned at the top and the bottom of control panel 340, during locating, to the negative position pulse that adds of addressing electrode (not shown).When digital drive panel 310 was two, the negative time that adds position pulse during locating, when being one than digital drive panel 310, the negative time that adds position pulse shortened to some extent.During locating, two negative simultaneously times that add position pulse of digital drive panel 310 shorten, and therefore can carry out the high-speed driving of Plasmia indicating panel.Again, the digital signal acceptance division 370 of digital drive panel 310 forms a plurality of, then by the mass data transmission quantity of digital signal sending part 360 transmission, can distribute to a plurality of digital signal acceptance divisions 370, and data will be transmitted dispersedly.Therefore, eliminated the bottleneck of data transmission, the transmission of data is comparatively smooth and easy, and can prevent the delay of data transmission.The digital signal sending part 360 that illustrates control panel 340 among Fig. 6 so is not to be subject to this by a situation about forming, and can also be made up of a plurality of.Again, digital drive panel 310 can also not be by a plurality of but form by one.
The digital signal sending part 360 of connection control panel 340 and the data transfer mode that the digital signal acceptance division 370 of digital drive panel 310 transmits use differential signal (Differential Signal) mode to transmit.In differential signal (Differential Signal) mode, should use LVDS (Low VoltageDifferential Signaling) mode.Differential signal (Differential Signal) transmission mode as LVDS has the high-speed data treatment capacity, and low-power consumption work prevents to disturb (noise), and price is low, and characteristics such as high comprehensive and low EMI are therefore more effective than mode of the prior art.
As mentioned above, improve plasma display system among the present invention, make unit price thereby reduce.Again, improve plasma display system among the present invention, thereby reduce the interference (noise) of the data of screen displayed.
As mentioned above; though the present invention about plasma display system with preferred embodiment openly as above; right its is not in order to limit the present invention; any those skilled in the art; under the situation that does not break away from the spirit and scope of the present invention; can carry out various changes and modification, so protection scope of the present invention is as the criterion when looking the claim restricted portion that is proposed.
