[0047] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. The same reference numerals are used for the same components in the drawings, and repeated description of the same components will be omitted.

[0048] Figure 1 is a block diagram illustrating a display device according to an embodiment of the present invention.

[0049] Reference Figure 1 The display device may include a display panel 100 and a display panel driving unit. The display panel driving unit may include a driving control unit 200, a gate driving unit 300, a gamma reference voltage generating unit 400, and a data driving unit 500. The display panel driving unit may also include a power supply voltage generating unit 600.

[0050] For example, the drive control unit 200 and the data driver unit 500 may be integrated. For example, the drive control unit 200, the gamma reference voltage generator 400, and the data driver unit 500 may be integrated. The driver module that includes at least the drive control unit 200 and the data driver unit 500 as an integrated unit may be named a timing controller embedded data driver (TED).

[0051] The display panel 100 may include a display portion displaying an image and a peripheral portion disposed adjacent to the display portion.

[0052] The display panel 100 includes a plurality of gate lines GL, a plurality of data lines DL, and a plurality of pixels P electrically connected to the gate lines GL and the data lines DL, respectively. The data lines DL extend along a first direction D1, and the gate lines GL extend along a second direction D2 perpendicular to the first direction D1. The display panel 100 may further include a plurality of sensing lines SL connected to the plurality of pixels P.

[0053] In one embodiment of the present invention, the display panel 100 may be an organic light emitting display panel including organic light emitting elements. In one embodiment of the present invention, the display panel 100 may be a liquid crystal display panel including liquid crystals.

[0054] The drive control unit 200 may receive image data IMG and an input control signal CONT from an external device. For example, the image data IMG may include red image data, green image data, and blue image data. The image data IMG may include white image data. The image data IMG may include magenta image data, yellow image data, and cyan image data. The input control signal CONT may include a main clock signal and a data enable signal. The input control signal CONT may also include a vertical synchronization signal and a horizontal synchronization signal.

[0055] The driving control unit 200 may generate a first control signal CONT1 , a second control signal CONT2 , a third control signal CONT3 , and a data signal DATA according to the image data IMG and the input control signal CONT.

[0056] The driving control part 200 may generate the first control signal CONT1 for controlling the operation of the gate driving part 300 according to the input control signal CONT and output the first control signal CONT1 to the gate driving part 300. The first control signal CONT1 may include a vertical start signal and a gate clock signal.

[0057] The driving control part 200 may generate a second control signal CONT2 for controlling the operation of the data driving part 500 according to the input control signal CONT and output the second control signal CONT2 to the data driving part 500. The second control signal CONT2 may include a horizontal start signal and a load signal.

[0058] The driving control unit 200 may generate a data signal DATA according to the image data IMG and output the data signal DATA to the data driving unit 500 .

[0059] The driving control part 200 may generate the third control signal CONT3 for controlling the operation of the gamma reference voltage generating part 400 according to the input control signal CONT and output the third control signal CONT3 to the gamma reference voltage generating part 400 .

[0060] The gate driver 300 may generate a gate signal for driving the gate line GL in response to the first control signal CONT1 received from the driver control unit 200. The gate driver 300 may output the gate signal to the gate line GL. For example, the gate driver 300 may sequentially output the gate signal to the gate lines GL. For example, the gate driver 300 may be integrated with the peripheral portion of the display panel 100. For example, the gate driver 300 may be mounted on the peripheral portion of the display panel 100.

[0061] The gamma reference voltage generator 400 may generate gamma reference voltages VGREF in response to the third control signal CONT3 received from the driving control part 200. The gamma reference voltage generator 400 may provide the gamma reference voltages VGREF to the data driving part 500. The gamma reference voltages VGREF may have values corresponding to the respective data signals DATA.

[0062] In an embodiment of the present invention, the gamma reference voltage generating section 400 may be disposed in the driving control section 200 or in the data driving section 500 .

[0063] The data driving unit 500 may receive the second control signal CONT2 and the data signal DATA from the driving control unit 200, and may receive the gamma reference voltage VGREF from the gamma reference voltage generating unit 400. The data driving unit 500 may convert the data signal DATA into an analog data voltage using the gamma reference voltage VGREF. The data driving unit 500 may output the data voltage to the data line DL.

[0064] The power supply voltage generating unit 600 may generate a power supply voltage required to drive at least any one of the display panel 100 , the driving control unit 200 , the gate driving unit 300 , the gamma reference voltage generating unit 400 , and the data driving unit 500 .

[0065] For example, the power voltage generator 600 may generate a first power voltage ELVDD and a second power voltage ELVSS applied to the pixels P of the display panel 100 and output the first power voltage ELVDD and the second power voltage ELVSS to the display panel 100. The second power voltage ELVSS may be lower than the first power voltage ELVDD.

[0066] Figure 2 It shows Figure 1 A block diagram of a drive control unit of a display device.

[0067] Reference Figure 2 The drive control unit 200 may include an image data analysis unit 210 and an image data conversion unit 220. The drive control unit 200 may analyze the image data IMG and determine whether to apply source emphasis. In one embodiment, the drive control unit 200 may output the data signal DATA while applying source emphasis to the image data IMG. In another embodiment, the drive control unit 200 may output the data signal DATA without applying source emphasis to the image data IMG. When source emphasis is applied to the image data IMG, the data voltage supplied to the plurality of pixels P may be changed. Accordingly, the charge amount of the plurality of pixels P may be increased.

[0068] In one embodiment, source boosting can be defined as an operation that modifies the data signal DATA to have a value higher than a target data signal, serving as a target data signal, when current image data currently being input is greater than previous image data input prior to the current image data being input. In another embodiment, source boosting can be defined as an operation that modifies the data signal DATA to have a value lower than the target data signal in order to reduce the charge rate of the pixel. However, when source boosting is applied, the color coordinates of the plurality of pixels P may be distorted.

[0069] More specifically, the image data analysis unit 210 may receive the image data IMG. In one embodiment, if the image data analysis unit 210 determines that the white balance of the image data IMG is within a set range, the image data analysis unit 210 may transmit a source enhancement disable signal S-DISABLE to the image data conversion unit 220. Since source enhancement is not applied, the color coordinates of the plurality of pixels P are not disturbed.

[0070] In one embodiment, when the image data IMG has a value determined by a gamma lookup table, the image data analysis unit 210 may determine that the white balance of the image data IMG is within the set range. In another embodiment, even when the image data IMG has a value within a predetermined error range of the value determined in the gamma lookup table, the image data analysis unit 210 may determine that the white balance of the image data IMG is within the set range. However, this is merely exemplary, and the basis for the image data analysis unit 210 to determine that the white balance of the image data IMG is within the set range is not limited to the above example.

[0071] If the image data IMG is determined to have a white balance that is not within the set range, the image data analysis unit 210 may selectively transmit a source enhancement enable signal S-ENABLE to the image data conversion unit 220. For example, the image data analysis unit 210 may compare the current image data with the previous image data. Based on the comparison result, the image data analysis unit 210 may transmit the source enhancement enable signal S-ENABLE to the image data conversion unit 220.

[0072] The image data conversion unit 220 may receive the source emphasis enable signal S-ENABLE from the image data analysis unit 210 to apply the source emphasis to the image data IMG. The image data conversion unit 220 may receive the source emphasis disable signal S-DISABLE from the image data analysis unit 210 to not apply the source emphasis to the image data IMG.

[0073] According to this, the image data conversion unit 220 can output the data signal DATA based on the image data IMG. The image data conversion unit 220 can send the data signal DATA to Figure 1 The data driving unit 500 is configured to:

[0074] When the source enhancement is applied, the color coordinates of the plurality of pixels P may be disordered. Therefore, after determining whether the white balance of the image data IMG is within the set range, the source enhancement may be selectively applied to improve the display quality of the display device.

[0075] Figure 3 is a flowchart illustrating a method of determining whether to apply source enhancement according to an embodiment of the present invention.

[0076] Reference Figures 1 to 3 , the image data analysis unit 210 may determine whether to apply source enhancement. In one embodiment, the image data analysis unit 210 may determine whether the white balance of the image data IMG is within the set range (S110). If the white balance of the image data IMG is determined to be within the set range, the image data analysis unit 210 may not apply source enhancement to the image data IMG. In other words, the image data analysis unit 210 may transmit the source enhancement disable signal S-DISABLE to the image data conversion unit 220. This prevents the color coordinates from being distorted, thereby improving the display quality of the display device.

[0077] If it is determined that the white balance of the image data IMG is not within the set range, the image data analysis unit 210 may compare the current image data with the previous image data (S120). In one embodiment, the current image data may be greater than the previous image data. In this case, the second pixel P2 (refer to FIG. 1 ) charged based on the current image data may not be charged. Figure 5 ) provides the target data voltage. That is, the second pixel P2 may not be charged to the desired target. Consequently, the display quality of the display device may be degraded. For example, the brightness of the display device may be reduced. Therefore, the image data conversion unit 220 may apply source boosting to output the data signal DATA at a value higher than the target. This can prevent the brightness of the display device from decreasing due to the increased data voltage outputted from the data driving unit 500.

[0078] Figure 4 is a flowchart illustrating a method for determining whether to apply source enhancement according to another embodiment of the present invention.

[0079] Reference Figure 1 、 Figure 2 and Figure 4 , the image data analysis unit 210 may determine whether to apply source enhancement. In another embodiment, the image data analysis unit 210 may determine whether the image data IMG includes values corresponding to red, green, and blue (S210). If it is determined that the image data IMG includes red, green, and blue image data, the image data analysis unit 210 may not apply source enhancement to the image data IMG. In other words, the image data analysis unit 210 may transmit the source enhancement disable signal S-DISABLE to the image data conversion unit 220. This prevents the color coordinates from being distorted, thereby improving the display quality of the display device.

[0080] If it is determined that the image data IMG does not simultaneously include the red image data, the green image data, and the blue image data, the image data analysis unit 210 may compare the current image data with the previous image data (S220). In one embodiment, the current image data may be greater than the previous image data. In this case, the target data voltage may not be provided to the second pixel P2 charged based on the current image data. In other words, the second pixel P2 may not be charged to the desired target. As a result, the display quality of the display device may be reduced. For example, the brightness of the display device may be reduced. Therefore, the image data conversion unit 220 may apply the source boost to output the data signal DATA at a value higher than the target. As a result, the brightness of the display device can be prevented from being reduced due to the increase in the data voltage output from the data driving unit 500.

[0081] Figure 5 is a diagram illustrating a pixel according to an embodiment of the present invention.

[0082] Reference Figure 5, the first pixel P1 may include a first red sub-pixel R1, a first green sub-pixel G1, and a first blue sub-pixel B1. The second pixel P2 may include a second red sub-pixel R2, a second green sub-pixel G2, and a second blue sub-pixel B2.

The second red sub-pixel R2, the second green sub-pixel G2, and the second blue sub-pixel B2 may be connected to a second gate line GL2.

[0084] In another embodiment, when the first red sub-pixel R1 and the second red sub-pixel R2 are turned on and the first green sub-pixel G1, the first blue sub-pixel B1, the second green sub-pixel G2, and the second blue sub-pixel B2 are turned off, the image data analysis unit 210 may compare the size of the previous image data corresponding to the first pixel P1 with the size of the current image data corresponding to the second pixel P2. If the current image data is greater than the previous image data, the source boost enable signal S-ENABLE may be provided to the image data conversion unit 220. If the current image data is less than or equal to the previous image data, the source boost disable signal S-DISABLE may be provided to the image data conversion unit 220.

[0085] In yet another embodiment, when the first blue sub-pixel B1 and the second blue sub-pixel B2 are turned on and the first red sub-pixel R1, the first green sub-pixel G1, the second red sub-pixel R2, and the second green sub-pixel G2 are turned off, the image data analysis unit 210 may compare the size of the previous image data corresponding to the first pixel P1 with the size of the current image data corresponding to the second pixel P2. If the current image data is greater than the previous image data, the source boost enable signal S-ENABLE may be provided to the image data conversion unit 220. If the current image data is less than or equal to the previous image data, the source boost disable signal S-DISABLE may be provided to the image data conversion unit 220.

[0086] In yet another embodiment, when the first green sub-pixel G1 and the second green sub-pixel G2 are turned on and the first red sub-pixel R1, the first blue sub-pixel B1, the second red sub-pixel R2, and the second blue sub-pixel B2 are turned off, the image data analysis unit 210 may compare the size of the previous image data corresponding to the first pixel P1 with the size of the current image data corresponding to the second pixel P2. If the current image data is greater than the previous image data, the source enhance enable signal S-ENABLE may be provided to the image data conversion unit 220. If the current image data is less than or equal to the previous image data, the source enhance disable signal S-DISABLE may be provided to the image data conversion unit 220.

[0087] In yet another embodiment, when two selected from the first red sub-pixel R1, the first green sub-pixel G1, and the first blue sub-pixel B1 are turned on, and two selected from the second red sub-pixel R2, the second green sub-pixel G2, and the second blue sub-pixel B2 connected to the same data line as the two selected sub-pixels are turned on, the image data analysis unit 210 may compare the size of the previous image data corresponding to the first pixel P1 with the size of the current image data corresponding to the second pixel P2. If the current image data is greater than the previous image data, the source enhance enable signal S-ENABLE may be provided to the image data conversion unit 220. If the current image data is less than or equal to the previous image data, the source enhance disable signal S-DISABLE may be provided to the image data conversion unit 220.

[0088] Figure 6 is a diagram illustrating a pixel according to another embodiment of the present invention.

[0089] Reference Figure 6 , the first pixel P1 can represent a darker color. For example, the first pixel P1 can represent black. A first data voltage can be applied to the first pixel P1. The second pixel P2 can represent a relatively brighter color than the first pixel P1. For example, the second pixel P2 can represent gray or white. A second data voltage higher than the first data voltage can be applied to the second pixel P2. Because the second data voltage is applied after the first data voltage is applied, the second pixel P2 may not be charged to the desired amount. To prevent this, the source boost can be applied to the image data IMG corresponding to the second data voltage to increase the second data voltage before output. For example, if the first data voltage is 1V and the second data voltage is 5V, the second pixel P2 may only be charged to 4.8V. To prevent this, the source boost can be applied to output the second data voltage at 5.2V, thereby charging the second pixel P2 to 5V.

[0090] Accordingly, the display device according to the present invention can prevent the color coordinates of the plurality of pixels P from being disordered and prevent the brightness of the plurality of pixels P from being reduced.
