Definitions

  • the present invention relates to a method for processing video pictures for display on a display device as well as to an apparatus for carrying out said method.
  • the invention relates to a method which improves the brightness and/or the picture quality of pictures which are displayed on matrix displays like plasma display panels (PDP) or other display devices based on the principle of duty cycle modulation (pulse width modulation) of light emission.
  • PDP plasma display panels
  • duty cycle modulation pulse width modulation
  • the Plasma technology makes possible to achieve flat color panels of large size and with very limited depth without any viewing angle constraints.
  • the size of the displays may be much larger than the classical CRT picture tubes would have ever been allowed.
  • a Plasma Display Panel utilizes a matrix array of discharge cells which could only be “ON” or “OFF”. Also unlike a CRT or LCD in which gray levels are expressed by analog control of the light emission, a PDP controls the gray level by modulating the number of light pulses per frame. For that purpose, each frame will be decomposed in sub-periods called "sub-fields”.
  • an erase operation will remove all the stored charges to prepare the cell for new cycle.
  • the PDP controls the gray level by modulating the number of light pulses per frame.
  • This time modulation will be integrated by the eye over a period corresponding to the human eye time response.
  • a 8-bit representation of a luminance level is very common and will be taken as example used to simplify the disclosure.
  • each level will be represented by a combination of the 8 following bits: 1 - 2 - 4 - 8 - 16 - 32 - 64 - 128
  • the frame period will be divided in 8 lighting periods (called sub-fields), each one corresponding to one of the 8 bits.
  • the number of light pulses for the bit "2" is the double as for the bit "1", and so forth.
  • the standard principle used to generate this gray modulation is based on the ADS (Address Display Separated) principle, in which all operations are performed at different time on the whole panel.
  • figure 1 represents an example of ADS principle based on an 8-bit encoding scheme with only one priming at the beginning of the frame.
  • Each sub-field SF1, SF2, SF3 ?? SF8 comprises an erase period, an addressing period and a sustain period as shown in detail in figure 2.
  • the addressing operation is a selective operation which is done line by line.
  • the overall duration of the addressing period is commonly called addressing time and represented on the figures with T ad . On standard panels, this time is equivalent to the time used for each line (T l ) multiplied by the number of lines (N) since the addressing time T l is the same for all lines. This principle can be seen on figure 3.
  • the only variation which can be found in the plasma field is a variation depending on the sub-field itself.
  • the addressing time for all lines stays the same inside one sub-field writing stage but is different from sub-field to sub-field.
  • the addressing time becomes shorter when the sub-field weight increases. This is due to the fact that the more sustain a sub-field contains the better the addressing efficiency is. Therefore this addressing time can also change depending on the power management.
  • APL Average Power level
  • the addressing time of standard panel stays the same from one line to the other despite the fact that the panel is not homogeneous as well as the influence of various operation like priming, sustaining and so on.
  • the present invention proposes a new addressing method which, at least:
  • the present invention relates to a method for processing video pictures for display on a display device comprising a plurality of lines constituted by luminous elements called cells corresponding to the pixels of a picture, wherein the time duration of a video frame is divided into a plurality of sub-field periods during which the cells can be activated for light emission, a sub-field period being divided into an addressing period wherein the plurality of lines is scanned line by line, a sustaining period and an erasing period, characterized in that, in the addressing period, the addressing time is different for at least one line.
  • the speed factor f(n) is function of one ore more of the following characteristics :
  • the speed factor f(n) is determined experimentally by measuring the discharge lag time (DLT) and taking for each line the worse value of the DLT to define the overall speed factor.
  • DLT discharge lag time
  • the speed factor f(n) is determined one time for a specific panel technology and stored in a memory of a panel control device.
  • the present invention relates also to an apparatus for carrying out the method including a peak white enhancement (PWE) control circuit comprising a memory for storing the speed factor associated to each line.
  • the memory is a PROM or a look up table (LUT).
  • the length of the addressing period will be different from line to line, as shown by the length of the addressing pulses Tl,1; Tl,2; Tl,3; Tl,N-1; Tl,N of the different lines line1, line2, line3 Vietnameselinen-1, line-N.
  • the length of the addressing period of at least one line or of groups of lines is different from the length of the addressing period of the other lines or other groups of lines.
  • the overall addressing time per sub-field becomes: where N represents the total number of lines.
  • T l (SF) will be similar to the standard addressing time known today (e.g. shown in Table B) and will follow the same rules.
  • a plasma panel structure comprises a black plate 1 on which are located ribs 2.
  • the ribs defined the walls of the cells.
  • the data electrodes are deposited between the ribs and are covered with different kinds of phosphors 3 giving the three colors RGB.
  • a seal 4 is deposited on the borders of the plate. The height of the seal is higher that the height of the ribs.
  • the panel also comprises a front plate 5 which receives the line electrodes.
  • the writing operation is done through a discharge between the data electrode (vertical) located on the back plate 1 and the line or scan electrode (horizontal) located on the front plate 5. Therefore, the efficiency of the discharge will depend on the distance between the two plates 1,5 determined by the height of the ribs. This distance should stay constant among the screen but, due to technology issues, this is not the case. In fact, the distance between the two plates is bigger at the border of the plate because the seal is higher than the ribs themselves. This is illustrated on Figure 6. This figure shows that the distance between data electrode and scan electrode is the biggest (seal height) at the border of the panel and decreases towards the minimal one (ribs height) in the middle of the panel.
  • the speed factor for the panel homogeneity f h (n) will have a behavior as described on the graphic represented on Figure 7 giving the speed factor function of the position along a line.
  • the curve has been drawn for a single scan WVGA panel with 480 lines addressed one after the other from the top up to the bottom.
  • various other configurations can be used with more or less lines, reverse addressing order, dual scan, and so on.
  • the writing operation can be preceded by a kind of pre-ionization of cells called priming, which improves the writing process.
  • priming a kind of pre-ionization of cells
  • some charges are set inside the cell to reduce its inertia.
  • this priming efficiency will decrease with the time as well as the charges will decrease with the time too.
  • the first lines written directly after the priming operation could be addressed much faster than the ones written at the end (last lines). Due to that behavior, the corresponding speed factor fp(n) will have a behavior as described on the graphic of figure 8.
  • the writing operation is based on the generation of a charge inside the cell that will be sustained later. As in the case of the priming charges, the writing charges will also decrease with the time before the sustain operation occurs. In other words, the lines which are located shortly before the sustain period (last lines) can be addressed faster than the other (first lines). Due to that behavior, the corresponding speed factor f s (n) will have a behavior as described on the graphic of figure 9.
  • the overall speed factor will be a combination of one or more of the above speed factors.
  • the overall speed factor will depend of the fact that each sub-field is preceded or not by a priming operation as described for example in WO 00/46782 filed in the name of the same company.
  • ⁇ PSF ( n ) ⁇ h ( n ) ⁇ ⁇ p ( n ) ⁇ ⁇ s ( n ) as shown on the figure 10.
  • the evaluation of the overall speed factor can be made experimentally rather than theoretically.
  • the discharge lag time (DLT) or writing discharge jitter will be measured among the screen for the case of primed and not-primed sub-fields. This measurement is made using a light sensor adapted to the IR emission occurring during the writing discharge. Then the measurement of the delay between the start of the writing operation and the discharge define the so-called DLT. The worse case of the DLT should be measured for each line in order to define the overall speed factor.
  • the addressing speed chosen for a specific panel is made in order to have a perfect response fidelity and homogeneity on the whole screen with a certain voltage margin for writing and sustaining. These kinds of measurements have lead to the definition of addressing table as shown on tables A and B.
  • the addressing speed may be the same for groups of lines. It is modified for at least one line Then, the speed of each line can be adapted so that the worse line will be at 2.1 ⁇ s. This is illustrated below for the case of one sub-field with priming and one sub-field without priming.
  • Figure 14 represents a possible implementation of an apparatus for carrying out the method of the invention.
  • This type of apparatus is already described in PCT application WO 00/46782. It comprises a video degamma circuit 10. RGB data from circuit 10 is analyzed in a an average power measure circuit 11 which gives the computed average power value (APL) to the PWE (peak white Enhancement) control circuit 12
  • APL computed average power value
  • PWE peak white Enhancement
  • the control PWE circuit 12 consults its internal power level mode table located in a LUT and directly generates the selected mode control signals for the other processing circuits. It selects the sustain table to be used and the subfield encoding table to be used (CODING). It also controls the writing of RGB pixel data in the frame memory 14 (WR), the reading of RGB subfield data from the second frame memory 14 (RD), and the serial to parallel conversion circuit 15 (SP). Finally it generates the SCAN and SUSTAIN pulses required to drive the PDP driver circuits. Also in that case, the length of the addressing signal (addressing speed) will be taken from the LUT 16 and this, for each line of the panel.
  • Two frame memories are required. Data is written pixel-wise, but read sub-field-wise. In order to read the complete first sub-field a whole frame must already be present in the memory. In a practical implementation two whole frame memories are present, and while one frame memory is being written, the other is being read, avoiding in this way reading the wrong data. In a cost optimized architecture, the two frame memories are probably located on the same SDRAM memory IC, and access to the two frames is time multiplexed.
