The system relates to the circuit configuration for controlling the electro-excitation light (EleCtr〇luminescence: hereinafter referred to as el) display element. , , /, Temple is driven [Prior Art] Self-illuminating elements in rural pixels are used for electroluminescence: the device is a self-illuminating type, and has the advantage of being wide-ranging: the force is small, etc., as a substitute for 'Caiguang::-cafe' And the display tube (Cath〇de Ray ue, CRT) and other devices are attracting attention. Membrane Electron:; The middle two pixels are provided for individually controlling the EL element. The active matrix type of the EL element can be a high-definition display device. For the clothing, it is expected that the first matrix "no" η column 111 rows of active matrix type EL display circuit configuration. In this EL display, the η is extended in the direction of the column line GL, and the data lines of the plurality of lines are organic: two "the direction of the king line extends. In addition, each pixel system has, (di-one TFT) 21 and keeps Capacitor Cs. Close the door! : TmP! is connected to the inter-pole line gl and the data line dl, and is turned on in the open-pole armor 1 U (the k-number is selected). At this time, the signal is supplied to the data line Dl. Between the first TFTi and the second tft2i, 337094 1263186 is connected to the second TFT 21. The second TFT 21 is supplied with the voltage of the data signal supplied from the first TFT 10/the second TFT 21, and the second TFT 21 supplies the corresponding voltage value from the electric TVL. The current flows to the organic component 5, and the rainbow element 50 is recombined in the light-emitting layer and is injected from the cathode, and the illuminating molecule is restored to the substrate state. The luminescence is generated. The organic EL element 5 〇 = degree system is almost the same as the supply to the element 5 〇, and in each pixel, by controlling the corresponding data signal two elements wide stream, so as to correspond to the information Image display. The light is illuminated and is performed on the entire display device. The display device is necessary in order to achieve high-quality display, with a brightness due to light shoots item number of the shell, while the real breaking the organic EL element 50

In the organic main (four) formation, the second tft21 disposed between the right side 50 of the driving power line VL requires that even if the current flows in a few miles of 兀5兀, the E ^ ̄ , , , , , , , , , , , , , 1卞]U's (four) pole potential produces no turbulent current and does not change. Connection == As shown in the figure, more than one is used: source pole example,: two = line VL, and the drain is connected to the organic rainbow element 5. The yang, the hunter is the potential difference Vgs between the voltage between the voltage and the upper voltage applied to the corresponding data signal, and the source finite current P can be controlled. When the channel TFT is used as the second TFT 21, the source is connected to the driving power source line VL, and the source is 317094 1263186 and ! The potential difference between the poles is used to control the immersed current, that is, the supply current, ... the current of the component 50, so if the driving power line v / the worker is supposed to be organic red, the voltage of each component 5 变动 1、 1, the voltage changes, for example The second one displayed during a certain frame (for example, a full-scale white 箄.

In addition, the source potential of (1) 0 is used. The TFT "reset TFT 30 of the organic EL element 5" is connected to the holding electric...: F 0 accepts the reset pulse. Between VSS, this TM0 is connected to the pole. Corresponding to the data signal, the potential of the second and second poles of the gate is also set, that is, the potential of the second TFT20. Therefore, the selection signal at the center of the heart is at: and the data signal is output to the data line team. The reset pulse is applied to the reset line RSL to turn on Tm 〇. Thereby, the potential of 317094 7 1263186 is set, and the source is lowered by 1 FT10 and the third TFT 30, and the potential difference of the material signal is supplied to the second TFT 20. The gate of the current second TFT 20 corresponds to the potential of the data signal to the power supply Vss. Further, if it is not turned on, it can be maintained in the power supply Cs (4), and the potential difference is applied from the driving power supply line VL to the organic EL element 50.

""The above-mentioned component driving power is used as the circuit element 317094 9 1263186 for controlling the driven component, whereby the circuits which are normally not usable as the display region can be reduced in i pixel regions. The area of the component is minimized. In addition, the power supply line is independently controlled for each column and each row formed in a matrix, and two transistors 5 are formed by an n-channel type thin film transistor and are connected to the component drive. The source potential of the driven element of the transistor (electrode potential on one side of the holding capacitor) is a sufficiently low potential, and a data signal can be applied to the gate of the transistor for driving the element. Therefore, it can be charged corresponding to the data signal. The holding capacitor (between the gate and the source of the element driving transistor) is surely held by the heater. The other aspect of the present invention is a display device for displaying the driven element of each pixel. The driving method is to set the data line to a specific pre-charging potential before outputting the corresponding data signal in the corresponding display. The power supply line is 'the setting potential for setting the non-operating potential of the driven element to the source of the element driving transistor, and the switching transistor for controlling the conduction to φ via the output selection signal to the selection line, The element driving transistor is operated, and the source of the element driving transistor is set to be a non-operating potential of the driven element via the power supply line, and then a data signal is output to the tributary line. In the above driving method, the selection signal outputted to the selection line is lowered, and the switching transistor is not turned on and is disposed between the element driving transistor and the gate line. The potential shifting capacitor 5 shifts the gate potential of the element driving transistor to the non-conduction direction of the transistor, and thereafter increases the operation power and system correspondence of the source 10 317 094 1263186 source line to the driven element.

... (Position) The parent becomes the potential (H period P), as shown in Fig. 3 (4), the order is ~ to the data line DJL of the corresponding pixel.) The precharge signal is output VL. Specifically, for example, from the 9 Ί疋 signal to the power supply line), it is reduced to the *organic EL element. The potential is lower (the lower setting of the power signal bit: the cathode of the 0 is about the same as the continuation of the white 0 season 乂 low.疋 potential. By this, during the period of electricity. When the child/original line VL is put into the timing t2, the signal is selected, and the TPTM is selected, and the potential is raised to the selection and the first FT] is turned on. In this case, the selection signal becomes ίί bit DL. This pre-charge ^ : ^ pre-charge signal has been turned to the data line (in transistor C 2: can make the 2tfti2 reach the full conduction level. That is, the conduction of the ni / domain) The sufficiently high power does not depend on the high potential of the source-drain voltage-to-pole current Id. This is enough to cause the pre-charge signal to be applied between the pole and the source during the period P3. The opening of i2::10 is available on the same day, and the L-level setting signal is output to the gate of the electric ^1νϊ, which is discharged through the second TFT] 2 in the on state, and between / history. Becomes low - v) equal to the set signal. As described above, the anode of the second TFT]2 is connected to the anode of the 317094 14 1263186 EL element 50, and the organic EL element 5 of the configuration of the signal is:: the potential is set to the diode. u + w generates the organic E] L element 5 〇 ''. Therefore, the state and the amount of current flowing into the element are quenched, and the anode is in a state in which the non-conducting electric charge is discharged through the second TFT 12, and the organic (the source of the TFT2 is inactive). Then, the source of the 2 + + pole is connected to the source of the holding capacitor, and the source potential of the 2 + 2tfti 2 of the holding capacitor Cs is fixed to the bank 2 (the first bit.

In the timing Μ, lowering the selection signal to the non-selection ^: quasi-conducting and not turning on the 317094 15 1263186] TFT10, after considering the f-thickness of the f-material, the first TFT 1 Θ is not turned on, and the P is It is true that there is only P5. After the period p5, *日士' and set a specific length of the period, output pre-charge signal to the data line DL^i5, as shown in Figure 3 (a) potential (Vs) g Change to the pre-charge potential. In addition, the 'from the data signal signal is raised from the set potential to the Η level +:, the power line of the original line VL is captured by the Cs, and the potential is used. In the state of the voltage Vgs, the electric shovel > bit, and the current corresponds to the held electric 虔Vgsf"^' to switch to the action power 5 繁 2 TF T1 9 ώΑ, 匕攸琶 source line VL·流涵至弟Between the source and the source of the 2TFT12, this current is supplied to the anode of the right-handed P-passer 50. Thus, in the organic anal Piece ^ has a branch EL selects the pixel, corresponding to the holding capacitor ^: the current between the field and the source of the 2TFT12, the source of electricity, the poor current electric dust (the brightness of the first current) The illuminating. And the performance is carried out here, because the potential offset uses the capacitor Cp pole, and the supply selection signal to the pixel between the selection of the timing t4, go; ni ruin. Tian Hao chooses to drop to the L level, and the sixth drop, and the action to lower the 2TTT12 M m 'P corresponds to the action of displaying the internal intersection as the "internal potential". For example, when the second TFT 12 is turned on and the organic red element is turned on, the capacitor is held. Keep the 2TFT12 action value. U brother is in the entrance to the door L brother, see, in the month, due to the second ΤΤΤΊ? Therefore, in the descending timing of the selection signal, you can reduce... to offset the gate potential of 2TFT12, to, 2, 9 FT]? . The closing of F1, ii, *, k is so that the black level can be achieved quickly and surely. Further, the electric value shifting capacitor Cp can use a so-called parasitic capacitance formed between the gate and the drain of the second cookie 317094 16 1263186. Of course, in addition to this parasitic capacitance, a capacitor electrically connected in parallel with the parasitic capacitance can be formed. The capacitance value of the parasitic capacitance is not 〇, and the capacitance ratio rc (= Cp/Cs) of the potential offset capacitor Cp and the holding capacitor Cs is 0 < rc, and the potential offset capacitor C p is sufficiently utilized. The offset function '1·c is set to 0.3 or more, for example, about 0.3 or about 0.5. When the black level of the data signal is limited, that is, when the black level is not higher than a certain level due to the operation range of the circuit on the data signal processing side, it is preferable to increase the potential offset. Use the capacitance value of the capacitor Cp, as described above, so that re is about 0 · 3 or more (for example, about 0 · 5). Conversely, when the black level potential of the data signal can be lowered, or when the life of the EL element is emphasized as described later, it is preferable to reduce the capacitance value of the potential offset capacitor Cp, for example, set to re 0.1. When the left and right re re is about 0.1, the offset function of the potential shift capacitor Cp is extremely small, but the black level potential of the data signal can be set low, thereby achieving a fast and accurate black level. Implementation. When the potential offset capacitor Cp is large, although the second TFT 12 can be surely turned off at the timing t4, when the cathode voltage Cv of the EL element is relatively low with respect to the selection signal system, the Cp exists. In particular, during the Η level of the selection signal, the gate potential of the second TFT 12 is relatively high with respect to the cathode voltage Cv, and the amount of current flowing through the EL element 50 tends to increase. Fig. 4 is a graph showing the characteristics of the current Io]ed flowing through the EL element when the cathode voltage Cv is changed, and when Cp/Cs(rc) is set to 1/10, and when it is set to 3/1 0, The cathode voltage Cv and the current flowing through the EL element (action electric 317094 1263186) Ioled are specifically changed. As shown in Fig. 4, when cv becomes low, Cp/Cs is one of 3/10, and the change in the operating current I〇kd with respect to the voltage change of cv is large. For example, the operating threshold of the EL element may vary due to the aging of the EL element, and the change in the operating threshold of the EL element may be regarded as the change of cv in Fig. 4 as viewed by the gate of the second TFT 12. That is, from Fig. 4, when the operating threshold of the EL element is changed, the change in the driving current Ioled becomes large. When it is preferable to extend the life of the EL element 5A which is accelerated and deteriorated as the amount of supplied current is increased, it is desirable to reduce the change of the drive current i〇ied with respect to the change of the CV. It is preferable to set Cp to be small. The element axis 5 is a diagram for explaining the overall operation of driving a plurality of pixels in order to prevent the X from being used first. The action of the pixels of each column is as described above, and the signal is rotated to the first! The column selection line GL "φ output... the alignment selection data line DL, and ... φ ^ out the pre-charge signal to each subsequent output power to the library / number to the first column of the power line. The display content line of the column is called m ^ in Fig. 5, the material signal is to the retention capacitor Cs, and only the line DL of the younger m仃 is taken as an example, and the selection line I in the column is ? The voltage of the data signal should be. Next, set DL to pre-charge the second kiss signal to L. After the level is set, set the data line level of action power: two set the power line of $1 column to Η the data line DL becomes the pre-financial scan _ period is for example , the period of time.

For the soil, it becomes a non-selection ^J times after the end of the GL drawing period, the second part, the horizontal sweep in the first column again selects the power line VL of the third column, and the next field is up to the level The action potential f. After the EL element is illuminated, the horizontal scanning period of the second column ends and reaches the horizontal W field of the second column, first the first precharge potential as shown in the first, then 5 Chart DL once again becomes 嘹 W (seven), does not take the L-level of the current macro, 唬 to the second line of the power line VL. ^ Η position of the e-cross as the brother 5 picture (4), the output of the first?
