Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an active matrix type display device, and more particularly to a display device using an active matrix type light emitting panel having a light emitting element such as an organic electroluminescence element.

[0002]

2. Description of the Related Art An organic electroluminescent element (hereinafter, referred to as an organic EL element) can control the light emission luminance by a current flowing through a light emitting element, and is constituted by arranging such light emitting elements in a matrix. The development of a matrix type display using a light emitting panel has been widely promoted. As a light emitting panel using such an organic EL element, a simple matrix type light emitting panel in which organic EL elements are simply arranged in a matrix, and an active matrix type in which a driving element including a transistor is added to each of the organic EL elements arranged in a matrix are used. There is a light emitting panel. Active matrix light-emitting panels have advantages such as lower power consumption and less crosstalk between pixels than simple matrix light-emitting panels, and are particularly suitable for large-screen displays and high-definition displays.

FIG. 1 shows an example of a circuit configuration corresponding to one pixel 10 of a conventional active matrix light emitting panel. Such a circuit configuration is described in, for example,
It is disclosed in Japanese Patent Publication No. 41057. In FIG. 1, F
The gate G of the ET (Field Effect Transistor) 11 (address selection transistor) is connected to an address scan electrode line (address line) to which an address signal is supplied.
The source S of the FET 11 is connected to a data electrode line (data line) to which a data signal is supplied. FET11
Is connected to the gate G of the FET 12 (driving transistor), and is grounded through the capacitor 13. The source S of the FET 12 is grounded, the drain D is connected to the cathode of the organic EL element 15, and the organic EL element 15
Is connected to a power source through the anode. The light emission control operation of this circuit will be described first.
When the ON voltage is supplied to the gate G of the FET 11, the FET 11
Causes a current corresponding to the voltage of the data supplied to the source S to flow from the source S to the drain D. Gate G of FET11
Is an off voltage, the FET 11 is cut off, and the drain D of the FET 11 is in an open state.
Therefore, while the gate G of the FET 11 is in the ON voltage, the voltage of the source S is charged in the capacitor 13, and the voltage is supplied to the gate G of the FET 12, and the FET 12 receives a current based on the gate voltage and the source voltage. It flows from the drain D to the source S through the organic EL element 15, and the organic E
The L element 15 is caused to emit light. When the gate G of the FET 11 is turned off, the FET 11 is in an open state, and the FET 12 holds the voltage of the gate G by the charge accumulated in the capacitor 13, maintains the drive current until the next scan, and operates the organic EL element 15 Is also maintained. Note that F
Since there is a gate input capacitance between the gate G and the source S of the ET 12, the same operation as described above can be performed without providing the capacitor 13.

A circuit corresponding to one pixel of a display panel that performs light emission control by active matrix driving is configured as described above, and when the organic EL element 15 of the pixel is driven, light emission of the pixel is maintained. The control of the brightness gradation of each pixel of the active matrix light emitting panel described above is performed by:
This is performed by amplitude-modulating the voltage applied to the gate G of the FET 12. That is, since the source-drain current of the FET 12 changes according to the voltage applied to the gate G, the gate G depends on the supplied input video signal.
By adjusting the magnitude of the voltage applied to the
The amount of drive current flowing through L element 15 can be adjusted. Therefore, the instantaneous luminance of the organic EL element 15 is adjusted by adjusting the amount of drive current of the organic EL element 15.

[0005]

However, in a display device which performs luminance gradation display by amplitude modulation as described above, the relationship between the voltage value applied to the gate of the drive FET and the current value flowing between the source and the drain, that is, In addition, since the current-voltage characteristics of the driving FETs are non-linear, the luminance gradation varies due to the characteristic variation between the driving FETs on the display panel surface, and it is difficult to perform high-precision multi-gradation display. .

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and it is an object of the present invention to provide an active matrix capable of performing high-precision multi-gradation display without variation in luminance gradation over the entire surface of a display panel. It is an object of the present invention to provide a display device of the type.

FIG. 4 shows a circuit configuration corresponding to one pixel of the active matrix light emitting panel according to the first embodiment of the present invention. This embodiment is different from the circuit configuration of the prior art shown in FIG.
A switch circuit 32 is provided between the connection point of the capacitor 13 and the gate G of the driving FET 12 to control conduction of the driving FET 12 to control light emission and non-light emission (light emission stop) of the organic EL element 15. It is a point. The switch circuit 32 includes two FETs 3 that perform switching in accordance with a light emission control signal from a light emission control driver 31 described later.

In the opposite case, light emission control for stopping light emission of the organic EL element 15 (OFF) is performed.

The light emission control operation in which the controller 26 controls light emission / non-light emission of the light emitting panel 30 based on the digital video signal data stored in the frame memory 24 to realize multi-tone display will be described with reference to FIG. And a time chart shown in FIG. First, when the digital video signal data is supplied to the frame memory 24, the controller 26 writes the digital video signal data for one frame into the frame memory 24. next,
Controller 26 issues a command to multiplexer 25 to output data of the first subfield (SF1). Next, the controller 26 issues a command to the row address counter 23 to designate the first row,
It issues a command to the column address counter 22 to designate the first column.

Thus, the designated address (first address)
The digital video signal data for one frame (row, first column) is converted into eight gradation display data corresponding to each subfield, and includes emission / non-emission data corresponding to the address of the pixel of the light emitting panel 30. The data is sequentially supplied to the multiplexer 25 as data. The controller 26 outputs the data of the first subfield from the data of the specified address (first row, first column) supplied to the multiplexer 25 to the column driver 28. Column driver 2
At 8, the data is held by a data latch circuit (not shown) provided in the column driver 28.

Next, the controller 26 issues a command to the column address counter 22 to update one column. That is, a command to designate the second column is issued to the column address counter 22. This allows the address (first
Row, second column) is specified and the address (first
(Row, first column) is repeated. In this manner, the controller 26 causes the data latch circuit of the column driver 28 to hold the data of all the columns of the first row by repeating the above-described operation sequentially for each column of the first row.

After all the column data of the first row is latched, the controller 26 writes each of the column data of the first row to the corresponding pixel of each column, as shown in FIG.
That is, the address selection FET 11 corresponding to each pixel
Is made conductive. At the same time, the controller 26 controls the light emission control driver 31 to supply a control signal for turning on the switch circuit 32 (light emission control ON), thereby causing the organic EL element of the pixel having data indicating light emission to emit light. The controller 26 further sends a signal to the light emission control driver 31 to instruct the organic EL element to stop light emission when a predetermined light emission period (T L1 ) elapses for the first subfield. Supply. The light emission control driver 31 applies an organic EL to all the switch circuits 32 in the first row.
Control signal to stop light emission of device (light emission control OFF)
And the organic EL element does not emit light.

The controller 26 issues a command to designate the row address counter 23 to the second row as a step after all the column data of the first row is latched.
An instruction to designate the column address counter 22 as the first column is issued. In the same manner as the operation for the first row described above, the second
Control is performed so as to perform data latch of all column data of the row. After latching all the column data of the second row, the light emission control operation of the pixels of each column of the second row is executed in the same manner as in the case of the first row described above.

The controller 26 performs such an operation over all the rows (that is, the first to m-th lines), so that all the pixels of the light emitting panel 30 correspond to the data of the first subfield. Light emission control can be performed. Next, the controller 26 issues a command to the multiplexer 25 to output data of the second subfield. Thereafter, the controller 26 repeats the same operation as in the case of the first subfield described above, and emits light corresponding to the data of the second subfield.

In this manner, light emission corresponding to the first to eighth subfields is performed.
As a feature of the present invention, since a means for stopping light emission of the light emitting element after a predetermined light emission period elapses for each subfield is provided, an arbitrary light emission period shorter than the address period (T A ) can be set as a sub-field. Can be assigned to fields. That is, when the light emission stop means is not provided, the light emission period shorter than the address period cannot be allocated to the subfield because the light emission (or non-light emission) of the pixel is updated at the start of the address period of the next subfield. Until then, the light emission of the pixel that has been emitting light cannot be stopped, and the next subfield cannot be started until the end of the address period, which is the period required for scanning all the rows.

FIG. 5 shows the k-th subfield (1 ≦ k ≦
8) shows a case in which light emission of each line is controlled in a light emission period shorter than the address period (T A ). Under the same control as described above by the controller 26, each row is controlled to emit light in a predetermined light emission period (T Lk ) set for this subfield. For example, one frame is 6
When displaying at 0 Hz, one frame is about 16.7 milliseconds (ms). Here, the address period is set to 0.84 ms.
(40% × 1/8 of one frame period), the light emission period in the first subfield (1 /) is set to 1
An example will be described in which each value is set to be equal to or less than / 2, for example, 5 ms. At this time, the light emission periods in the subfields after the second subfield are respectively 1/2 1 , 1/2 2 , 1/2 3 ,... Of the light emission period of the first subfield.
.. 2.5ms, 1.25ms, 0.6 which is 1/2 7
25 ms,..., 0.039 ms. Therefore, in this case, the light emission period in the subfields after the fourth subfield (the fourth to eighth subfields) is shorter than the address period (T A = 0.84 ms), but the desired light emission period for each subfield is set. Is controlled to have

As described above, the display of one frame is completed when the display control from the first subfield to the eighth subfield is completed. Thereafter, the controller 26 rewrites the data stored in the frame memory 24 to data corresponding to the next frame, and controls the display of the next frame. Therefore, according to the present invention, light emission can be controlled in any light emission period shorter than the address period for each subfield by the above-described light emission stop control, so that a wide range of gradation display is possible.

FIG. 7 shows a circuit configuration corresponding to one pixel of an active matrix type light emitting panel according to a second embodiment of the present invention. This embodiment differs from the first embodiment in that the switch circuit 32 has an FET 35 connected in parallel to the capacitor 13. That is, the drain D of the FET 35 is connected to the connection point between the source S of the FET 11 and the capacitor 13, and the source S is grounded. Therefore, when the FET 35 is turned on in response to the control signal supplied to the gate G, the organic EL
Light emission of the element 15 is stopped.

FIG. 8 shows a circuit configuration corresponding to one pixel of a light emitting panel according to a third embodiment of the present invention. This embodiment is different from the above-described embodiment in that the switch circuit 32 has an FET 36 connected in series between the capacitor 13 and the gate G of the FET 12.
That is, the drain D of the FET 36 is connected to the connection point between the source S of the FET 11 and the capacitor 13, and the source S
Is connected to the gate G of the FET 12. Therefore, when the FET 36 is turned off in response to the control signal supplied to the gate G, the light emission of the organic EL element 15 is stopped.

FIGS. 9 to 11 show a circuit configuration corresponding to one pixel of a light emitting panel according to another embodiment of the present invention. Each embodiment differs from the above-described embodiments in that the switch circuit 32 includes an FET 37 connected in series with the organic EL element 15. That is, F
