Among the two cutting check lines 800 and 800', the main cutting check line 800 is connected to the control unit 400 through the flexible film 600.

For example, if the organic light emitting display panel 100 is not cut, one end of the cut check line 800 provided in the non-display area 112 is cut by the control unit 400, as shown in FIG. 1. ) and extends to the top of the non-display area 112 of the organic light emitting display panel 110 through the flexible film 600. The cutting check line 800 extending to the top of the non-display area 112 extends along the outer edge of the non-display area 112. That is, the cut check line 800 extends from the top of the organic light emitting display panel 100, through the left and bottom sides, and to the right of the organic light emitting display panel 100.

The other end of the cut check line 800 extending to the right of the organic light emitting display panel is connected to the control unit 400 through the flexible film 600 in an organic light emitting display device equipped with a single flexible film 600. is connected to

In an organic light emitting display device equipped with two or more flexible films 600, a light emitting device extends from the control unit 400 to the organic light emitting display panel through the flexible film 600 mounted on the left side of the organic light emitting display panel. The other end of the cut check line 800 may be connected to the control unit 400 through another flexible film 600 mounted on the right side of the organic light emitting display panel.

That is, when the data driver IC 300 is mounted on the organic light emitting display panel 100, the cut check line 800 electrically connects the organic light emitting display panel 100 and the main substrate 700. It can be electrically connected to the control unit 400 through a flexible film that connects it.

Next, as shown in FIG. 3, the control unit 400 generates a gate control signal (GCS) to control the driving of the gate driver 200 using a timing synchronization signal (TSS) input from an external system. ) and a data control signal (DCS) for controlling the operation of the data driver 300 are generated respectively.

In addition, the control unit 400 generates image data by rearranging input image data (Ri, Gi, Bi) transmitted from an external system, and then transmits the image data to the data driver IC 300. do. The data driver IC 300 converts the image data (Data) into data voltages (Vdata) and then supplies the data voltages (Vdata) to the data lines (DL1 to DLd).

In particular, the control unit 400 applied to the present invention can perform the function of determining whether the organic light emitting display panel 100 is cut, and for this purpose, a check signal (CS) and a top bottom control signal (TBC) are used. can be created.

A specific method by which the control unit 400 determines whether the organic light emitting display panel 100 is cut will be described in detail below with reference to FIGS. 6 and 7.

In order to perform the above-described function, the control unit 400 uses the timing synchronization signal (TSS) transmitted from the external system, as shown in FIG. 3, to input image data transmitted from the external system. A data alignment unit 430 for rearranging the fields (Ri, Gi, Bi) and supplying the rearranged image data to the data driver IC 300, and the gate control signal ( GCS), a control signal generator 420 for generating the data control signal (DCS), the check signal (CS) and the top-bottom control signal (TBC), and the check output to the cut check line 800. A determination unit 410 for determining whether to output the top-bottom control signal (TBC), depending on whether the signal CS is normally received, and information necessary for generating the control signals and rearranging the input image data. The image data (Data) generated in the storage unit 450 and the data sorting unit 430 for storage and the data control signal (DCS) generated in the control signal generating unit 420 are output to the data driver. The gate control signal (GCS) is output to the gate driver 200, the check signal (CS) is output to the cut check line 800, and the top-bottom control signal (TBC) is output to the first It includes an output unit 440 for outputting to the selection unit 480. The storage unit 450 may be included in the control unit 400, but as shown in FIG. 3, it may be configured independently from the control unit 400.

In particular, when the organic light emitting display device according to the present invention is turned on and starts operating, the determination unit 410 preferentially generates the check signal CS and outputs it to the cut check line 800.

When the check signal CS output to the cut check line 800 is received, the determination unit 410 may not perform any additional operation.

However, if the check signal (CS) output to the cut check line 800 is not received, the determination unit 410 generates the top bottom control signal (TBC) and sends it to the first selection unit 480. Can be printed.

Accordingly, the first gate driver 200a can change the direction in which gate pulses are output.

That is, the control unit 400, especially the determination unit 410, controls the first selection unit 480 using the top-bottom control signal (TBC) depending on whether the cut check line is cut. Accordingly, the first gate driver 200a can change the direction in which it outputs the gate pulses.

Detailed descriptions related to this are described in detail with reference to FIGS. 6 and 7 .

Next, the power supply unit 500 supplies power required to drive the first gate driver 200a, the data driver, and the control unit 400 to the first gate driver 200a, the data driver, and the control unit ( 400).

Next, the first gate driver 200 uses the gate control signals (GCS) transmitted from the control unit 400 to sequentially drive the left gate lines (GL1,... GLn-1, GLn+). 1... Supply the gate pulse (GP) to GLg-1).

Here, the gate pulse (GP) refers to a signal that can turn on the switching transistor (Tsw1) connected to the gate lines (GL1 to GLg). A signal that can turn off the switching transistor (Tsw1) is called a gate-off signal. The gate pulse (GP) and the gate off signal are collectively referred to as a gate signal.

The first gate driver 200a is formed independently from the organic light emitting display panel 100 and emits the organic light through a tape carrier package (TCP), chip-on-film (COF), or flexible printed circuit board (FPCB). It may be connected to the display panel 100, but may also be directly mounted within the organic light emitting display panel 100 using a gate in panel (GIP) method.

In order to sequentially output the gate pulses (GP) to the left gate lines (GL1,... GLn-1, GLn+1... GLg-1), the first gate driver 200a is shown in FIG. As shown in Figure 4, it may include a plurality of stages 201.

Each stage 201 outputs a gate pulse (GP) to a gate line connected to each stage, and the gate pulse (GP) can drive the next stage 201.

Among the left gate lines (GL1, ... GLn-1, GLn+1, ... GLg-1), the first stage (Stage 1) provided at the top of the organic light emitting display panel 100 is the Among the gate control signals (GCS) transmitted from the control unit 400, in particular, a gate start signal can be received.

The first stage (Stage 1) receiving the gate start signal outputs the gate pulse to the first gate line (GL1), and the gate pulse output from the first stage (Stage 1) is transmitted to the third stage (Stage 1). Stage 3) is activated.

That is, each stage (Stage 1 to Stage g-1) constituting the first gate driver 200a starts driving by the gate control signal (GCS) received by the first stage (Stage 1). , gate pulses can be output to the gate lines.

However, the gate control signals (GCS) for driving the first gate driver 200a, especially the gate start signal, are connected to the gate lines (GL1,... GLn-1, GLn+1,... GLg). In -1), it can be received at the g-1th stage (Stage g-1) provided at the bottom of the organic light emitting display panel 100.

In this case, the g-1th stage (Stage g-1), which has received the gate start signal, outputs the gate pulse to the g-1th gate line (GLg-1), and the g-1th stage (Stage g-1) outputs the gate pulse to the g-1th gate line (GLg-1). The gate pulse output from g-1) drives the g-3th stage (Stage g-3).

That is, each stage (Stage 1 to Stage g-1) constituting the first gate driver 200a is controlled by the gate control signal (GCS) received at the g-1th stage (Stage g-1). By starting driving, gate pulses may be output to the gate lines.

To explain further, the first gate driver 200a is connected from the first gate line GL1 provided at the top of the organic light-emitting display panel 100 to the g-th gate driver 200a provided at the bottom of the organic light-emitting display panel 100. Gate pulses may be sequentially output in the direction of the -1 gate line (GLg-1), and gate pulses may be sequentially output in the direction from the g-1th gate line (GLg-1) to the first gate line (GL1). You may.

The order in which the first gate driver 200a outputs gate pulses is determined according to the top-bottom selection signal (TBS) received from the first selection unit 480.

For example, if the top-bottom selection signal (TBS) is a signal that turns on the switches of the first switching unit 210, the first switching unit 210 receives a gate start signal transmitted from the control unit 400. Gate control signals (GCS) including can be transmitted to the first stage (Stage 1).

In this case, the first gate driver 200a may sequentially output gate pulses in the direction from the first gate line GL1 to the g-1th gate line GLg-1.

However, if the top-bottom selection signal (TBS) is a signal that turns off the switches of the first switching unit 210, the first switching unit 210 receives the gate control signal ( GCS) cannot be transmitted to the first stage (Stage 1).

The second switching unit 220 provided at the bottom of the first gate driver 200a is also connected to the first selection unit 480. In this case, between the first selection unit 480 and the second switching unit 220, there is a first inverter ( 250) is connected.

Accordingly, the top bottom selection signal (TBS), which turns off the switches of the first switching unit 210, can turn on the switches of the second switching unit 220.

The second switching unit 210, which is turned on by the top-bottom selection signal (TBS), sends a gate control signal (GCS) including a gate start signal transmitted from the control unit to the g-1th stage (Stage g- 1) It can be transmitted.

In this case, the first gate driver 200a may sequentially output gate pulses in the direction from the g-1th gate line GLg-1 to the first gate line GL1.

However, the gate control signals (GCS) that are actually transmitted to the first gate driver 200a through the second switching unit 210 are generated by the auxiliary control unit 400' rather than the control unit 400 described above. This is a signal transmitted from . A detailed description of this is provided below with reference to FIGS. 6 and 7 .

In the above description, the first inverter 250 is described as being provided at the bottom of the first gate driver 200a, but the first inverter 250 may be provided at the top of the first gate driver 200a. It may be possible.

Additionally, in the above description, the organic light emitting display device according to the present invention includes only the first gate driver 200a. In this case, only the left gate lines (GL1,... GLn-1, GLn+1... GLg-1) are provided in the organic light emitting display panel 100, and the left gate lines (GL1,... ... GLn-1, GLn+1... GLg-1) are connected to all pixels 110 provided in the organic light emitting display panel 100.

Next, the first selection unit 480 performs a function of selecting a direction in which the gate pulses are output from the first gate driver 200a. That is, the direction in which the gate pulses are output from the first gate driver 200a can be determined by the top-bottom selection signal TBS output from the first selection unit 480.

As shown in FIG. 1, the first terminal of the first selection unit 480 is connected to the power supply unit 500 that supplies the power required for the control unit 400, and the first selection unit ( The third terminal of 400 is connected to the first switching unit 210 and the second switching unit 220.

In this case, the first selection unit 480 uses a signal supplied from the power supply unit 500 according to the top bottom control signal (TBC) supplied through the second terminal from the control unit 400 to A bottom selection signal (TBS) is generated and output to the third terminal.

For this purpose, the first selection unit 480 may be configured as a switch.

For example, the first selection unit 480 may connect the power supply unit 500 to the first switching unit 210 and the second switching unit 220 according to the top-bottom control signal. , or a conversion unit that inverts the voltage transmitted from the power supply unit 500 may be connected to the first switching unit 210 and the second switching unit 220.

The first selection unit 480 can be basically set to connect the power supply unit 500 to the first switching unit 210 and the second switching unit 220.

Accordingly, a constant voltage can be supplied from the power supply unit 500 to the first switching unit 210 and the second switching unit 220 through the first selection unit 480.

In this case, the second terminal of the first selection unit may or may not be connected to the control unit 400.

For example, as shown in FIG. 1, the first selection unit 480 is not connected to the control unit 400.

That is, the main board 700 on which the control unit 400 is mounted is connected to the organic light emitting display panel 100 when the organic light emitting display device according to the present invention is supplied to the user. In this case, the control unit 400 is connected to the organic light emitting display panel 100. 400 is not connected to the first selection unit 480.

However, when the organic light emitting display device according to the present invention is supplied to a user, the auxiliary control unit 400' mounted on the additionally supplied auxiliary substrate 700' is 1 It is connected to the selection unit 480'.

The third terminal is connected to the first switching unit 210 and the second switching unit 220. In this case, the first inverter 250 is provided between the second switching unit 220 and the third terminal.

Accordingly, the signal supplied to the second switching unit 220 has a phase opposite to that of the top-bottom selection signal supplied to the first switching unit 210.

Next, as explained in the description of the first gate driver 200a, the first switching unit 210 operates according to the top-bottom selection signal (TBS) transmitted from the first selection unit 480. , performs a function of transmitting or blocking the gate control signals (GCS) transmitted from the control unit 400 toward the top of the first gate driver 200a.

In addition, the second switching unit 220 sends gate control signals toward the bottom of the first gate driver 200a according to the top-bottom selection signal (TBS) transmitted from the first selection unit 480. Performs the function of transmitting or blocking.

Gate control signals transmitted to or blocked by the first gate driver 200a through the second switching unit 220 are not signals transmitted from the control unit 400 provided on the main board 700, These are signals transmitted from the auxiliary control unit 400' provided on the auxiliary substrate 700'.

To this end, the first switching unit 210 and the second switching unit 220 are connected to an auxiliary first selection unit 480' provided on the auxiliary substrate 700', and the auxiliary first selection unit 480' is connected to the auxiliary first selection unit 480'. Unit 480' is connected to the auxiliary control unit 400'.

The first switching unit 210 and the second switching unit 220 may be configured independently from the first gate driver 200a, or may be formed integrally with the first gate driver 200a.

Since the first panel 100a is cut from the organic light emitting display panel 100, the cut check line 800 provided on the organic light emitting display panel 100 is also cut.

Therefore, the check signal CS output from the control unit 400 is not received by the control unit 400.

If the check signal CS is not received through the cut check line 800, the control unit 400 determines that the organic light emitting display panel 100 is cut. In this case, the control unit 400 may output a top-bottom control signal (TBC) that causes the first selection unit 480 to invert the voltage transmitted from the power supply unit 500.

However, as described above, since the first selection unit 480 and the control unit 400 are not connected, the power supply unit 500 operates on the first switching unit 210 and the second switching unit. It remains connected to unit 220.
