摘要： A plasma display device and a driving method thereof are provided to perform a stable reset discharge by supplying second and third main reset pulses during an (i+1)-th frame. A plasma display device includes a PDP(Plasma Display Panel,110), a controller(102), and a driving unit(106). The controller divides one frame into plural sub-fields, each of which includes a reset period, an address period, and a sustain period, and alternatively drives i-th and (i+1)-th frames. The driving unit supplies at least one main reset pulses to the PDP during a reset period of the i-th frame, and supplies main reset pulses to the (i+1)-th frame. The number of the main reset pulses for the (i+1)-frame is greater than that for the i-th frame. A waveform of the main reset pulse during the reset period of the i-th frame is different from that during the (i+1)-th frame.

摘要： An apparatus and a method for driving a display panel are provided to prevent an excessive voltage of electrode lines by using a scan voltage of a scan pulse with a negative level as a negative polarity sustain voltage. A display panel includes discharge cells on cross sections, which are defined by sustain and address electrode lines. Plural sub-fields are formed based on a grayness weighted value for performing a time division grayness display for every frame. Each of the sub-fields(SF) includes reset, address, and sustain discharge periods(PR,PA,PS). A scan pulse with a second level is sequentially applied to the sustain electrode lines(Y1-Yn), which is biased to a first level(Vsch), and a data pulse(Va), which is synchronized with the scan pulse, is applied to the address electrode lines during the address period. Sustain pulses with third and fourth level voltages(Vs,-Vs) are alternately applied to the sustain electrode lines during the sustain discharge period.

摘要： A plasma display apparatus having a function of compensating image sticking and a method for compensating image sticking are provided to prevent generation of image sticking by compensating for image data in an image sticking prediction region through analysis of the image data. First and second regions having a brightness difference are formed on a panel. Whether the brightness difference between the first and second regions is reduced according to the brightness variation of the second region is determined through input image data(S40). A driving voltage waveform for driving discharge cells is adjusted, so that a brightness difference due to image sticking of the first and second regions is compensated based(S60,S65).

摘要： An updatable PDP(Plasma Display Panel) device and an updating method thereof are provided to easily update a PDP module by enabling a user to update the PDP module without removing the PDP module from a signal processing board. An updatable PDP device includes a PDP module(200) and a signal processing board(100). The PDP module turns on/off discharge cells and displays an image. The signal processing board processes audio/video signals from a signal source and provides an updating program from an external device to the PDP module. The signal processing board includes a user selector(160), first and second interface units(120,130), a first controller(170), and a switching unit(150). The user selector outputs a first mode select signal for updating the PDP module. The first interface unit communicates with the PDP module. When the first mode select signal is received, the first controller outputs a first control signal for providing a communication path between the signal processing board and the PDP module.

摘要： A plasma display device is provided to improve image quality of the display device by removing bright spots at borders of afterimages by increasing the difference between a set-down minimum voltage and a bias voltage. A plasma display device applies a reset signal to a first electrode and a predetermined voltage to a second electrode during a set-down signal application period. The reset signal consists of a set-up signal and the set-down signal. A difference between the minimum value of the set-down signal and the voltage applied to the second voltage lies between 1.2 and 1.5 times the magnitude of a sustain voltage. The absolute value of the minimum set-down signal is smaller than a half of the sustain voltage. The absolute value of the voltage applied to the second electrode is smaller than the sustain voltage.
