[0135] Meanwhile, the signal processing device (170) can process various signals such as audio signals, video signals, and data signals. To this end, the signal processing device (170) can be implemented in the form of a system on chip (SOC).

[0136] Figure 4 is an internal block diagram of the display of Figure 2.

[0137] Below, the first display (180m) will be described.

[0138] Referring to the drawing, a display (180m) based on an organic light-emitting panel may include an organic light-emitting panel (210), a first interface unit (230), a second interface unit (231), a timing controller (232), a gate driver unit (234), a data driver unit (236), a memory (240), a power supply unit (290), a current detector unit (510), etc.

[0139] The display (180 m) receives a video signal (Vd), a first DC power source (V1) and a second DC power source (V2), and can display a predetermined image based on the video signal (Vd).

[0140] Meanwhile, the first interface unit (230) within the display (180 m) can receive a video signal (Vd) and a first DC power source (V1) from a signal processing device (170).

[0141] Here, the first DC power supply (V1) can be used for the operation of the power supply unit (290) and the timing controller (232) within the display (180 m).

[0142] Next, the second interface unit (231) can receive a second DC power supply (V2) from an external power supply unit (190). Meanwhile, the second DC power supply (V2) can be input to a data drive unit (236) within the display (180m).

[0143] The timing controller (232) can output a data driving signal (Sda) and a gate driving signal (Sga) based on a video signal (Vd).

[0144] For example, when the first interface unit (230) converts an input image signal (Vd) and outputs a converted image signal (va1), the timing controller (232) can output a data driving signal (Sda) and a gate driving signal (Sga) based on the converted image signal (va1).

[0145] The timing controller (232) can receive, in addition to the video signal (Vd) from the signal processing device (170), a control signal, a vertical synchronization signal (Vsync), etc.

[0146] In addition, the timing controller (232) can output a gate drive signal (Sga) for the operation of the gate drive unit (234) and a data drive signal (Sda) for the operation of the data drive unit (236) based on a control signal, a vertical synchronization signal (Vsync), etc., in addition to a video signal (Vd).

[0147] The data driving signal (Sda) at this time may be a data driving signal for driving RGB subpixels when the panel (210) has RGB subpixels.

[0148] Meanwhile, the data driving signal (Sda) may be a data driving signal for driving RGBW subpixels when the panel (210) has RGBW subpixels.

[0149] Meanwhile, the timing controller (232) can further output a control signal (Cs) to the gate driver (234).

[0150] The gate driving unit (234) and the data driving unit (236) supply scan signals and data signals to the organic light-emitting panel (210) through the gate line (GL) and the data line (DL), respectively, in accordance with the gate driving signal (Sga) and the data driving signal (Sda) from the timing controller (232). Accordingly, the organic light-emitting panel (210) displays a predetermined image.

[0151] Meanwhile, the organic light-emitting panel (210) may include an organic light-emitting layer, and in order to display an image, a plurality of gate lines (GL) and data lines (DL) may be arranged in a matrix form to cross each pixel corresponding to the organic light-emitting layer.

[0152] Meanwhile, the gate line (GL) may also be called a scan line because a scan signal is input.

[0153] Meanwhile, the data driving unit (236) can output a data signal to the organic light-emitting panel (210) based on the second direct current power (V2) from the second interface unit (231).

[0154] The power supply unit (290) can supply various power sources to the gate driver unit (234), the data driver unit (236), the timing controller (232), etc.

[0155] The current detection unit (510) can detect the current flowing in the subpixel of the panel (210). The detected current can be input to a processor (270) or the like for cumulative current calculation.

[0156] Meanwhile, the timing controller (232), gate driver (234), data driver (236), and memory (240) in the drawing can be implemented as a single integrated circuit (IC).

[0157] Accordingly, the timing controller (232), gate driver (234), data driver (236), and memory (240) may be named a drive control unit (285).

[0158] Meanwhile, the drive control unit (285) may include a buffer (not shown) that stores frame data.

[0159] In particular, the timing controller (232) in the drive control unit (285) can output a gate drive signal and a data drive signal based on frame data stored in a buffer (not shown) or memory (240).

[0160] The timing controller (232) or the driving control unit (285) can perform various controls within the display (180 m). For example, it can control the gate driving unit (234), the data driving unit (236), the timing controller (232), etc.

[0161] Meanwhile, the timing controller (232) or the driving control unit (285) can receive information on the current flowing in the subpixel of the panel (210) from the current detection unit (510).

[0162] In addition, the timing controller (232) or the driving control unit (285) can calculate the accumulated current of the subpixels of each panel (210) based on the current information flowing in the subpixels of the panel (210). The calculated accumulated current can be stored in the memory (240).

[0163] Meanwhile, the timing controller (232) or the driving control unit (285) can determine that burn-in has occurred when the accumulated current of the subpixels of each panel (210) exceeds the allowable value.

[0164] For example, the timing controller (232) or the driving control unit (285) may determine that a subpixel of each panel (210) has a burnt-in subpixel if the accumulated current of the subpixel is 300,000 A or more.

[0165] Meanwhile, the timing controller (232) or the driving control unit (285) may determine that a subpixel among the subpixels of each panel (210) is a subpixel predicted to be subject to burn-in when the accumulated current of the subpixel approaches the allowable value.

[0166] Meanwhile, the timing controller (232) or the driving control unit (285) can determine the subpixel with the largest accumulated current as the burn-in prediction subpixel based on the current detected by the current detection unit (510).

[0167] Meanwhile, the timing controller (232) or the driving control unit (285) may predict current information to flow in a subpixel based on an image signal from the signal processing device (170), regardless of the operation of the current detection unit (510), and determine a subpixel in which burn-in is predicted based on the predicted current information.

[0168] FIGS. 5A to 5D are drawings for reference in the description of the organic light-emitting panel of FIG. 4.

[0169] First, FIG. 5a is a drawing showing an example of a pixel in an organic light-emitting panel (210).

[0170] Referring to the drawing, the organic light-emitting panel (210) may have a plurality of scan lines (Scan 1 to Scan n) and a plurality of data lines (R1, G1, B1 to Rm, Gm, Bm) intersecting therewith.

[0171] Meanwhile, a pixel (subpixel) is defined in the intersection area of ​​the scan line and the data line within the organic light-emitting panel (210). In the drawing, a pixel (Pixel) having RGB subpixels (SR1, SG1, SB1) is illustrated.

[0172] Meanwhile, red organic light-emitting diodes, green organic light-emitting diodes, and blue organic light-emitting diodes are placed in the RGB subpixels (SR1, SG1, SB1), respectively.

[0173] Next, FIG. 5b is a drawing showing another example of pixels within the panel (210).

[0174] Referring to the drawing, the panel (210) may have a plurality of scan lines (Scan 1 to Scan n) and a plurality of data lines (R1, G1, B1, W1 to Rm, Gm, Bm, Wm) intersecting therewith.

[0175] Meanwhile, a pixel (subpixel) is defined in the intersection area of ​​a scan line and a data line within the panel (210). In the drawing, a pixel (Pixel) having RGBW subpixels (SR1, SG1, SB1, SW1) is illustrated.

[0176] Meanwhile, red organic light-emitting diodes, green organic light-emitting diodes, blue organic light-emitting diodes, and white organic light-emitting diodes are placed in the RGBW subpixels (SR1, SG1, SB1, SW1), respectively.

[0177] FIG. 5c illustrates an example of a circuit of a sub-pixel within a pixel of the panel of FIG. 5a or FIG. 5b.

[0178] Referring to the drawing, the sub-pixel circuit (CRTm) may be an active type and include a scan switching element (SW1), a storage capacitor (Cst), a data switching element (SW2), a first driving switching element (SW3), a first organic light-emitting layer (ODa), a second driving switching element (SW4), and a second organic light-emitting layer (ODb).

[0179] The scan switching element (SW1) is turned on according to an input scan signal (Vdscan) by connecting a scan line to the gate terminal. When turned on, the input data signal (Vdata) is transmitted to the gate terminal of the data switching element (SW2) or one end of the storage capacitor (Cst).

[0180] The storage capacitor (Cst) is formed between the gate terminal and the source terminal of the data switching element (SW2), and stores a predetermined difference between the data signal level transmitted to one end of the storage capacitor (Cst) and the DC voltage (VDD) level transmitted to the other end of the storage capacitor (Cst).

[0181] For example, if the data signal has different levels according to the PAM (Plus Amplitude Modulation) method, the power level stored in the storage capacitor (Cst) changes depending on the level difference of the data signal (Vdata).

[0182] As another example, when the data signal has different pulse widths according to the Pulse Width Modulation (PWM) method, the power level stored in the storage capacitor (Cst) changes depending on the difference in the pulse width of the data signal (Vdata).

[0183] Meanwhile, the data switching element (SW2) is turned on according to the power level stored in the storage capacitor (Cst).

[0184] Meanwhile, the first driving switching element (SW3) can be connected between the data switching element (SW2) and the first organic light-emitting layer (ODa).

[0185] Meanwhile, the second driving switching element (SW4) can be connected between the data switching element (SW2) and the second organic light-emitting layer (ODb).

[0186] Meanwhile, the first driving switching element (SW3) and the second driving switching element (SW4) can be connected in parallel.

[0187] Meanwhile, based on the public mode, when the data switching element (SW2) and the first driving switching element (SW3) are turned on, a first driving current (IDa) proportional to the stored power level stored in the storage capacitor (Cst) flows to the first organic light-emitting layer (ODa). Accordingly, the first organic light-emitting layer (ODa) performs a light-emitting operation.

[0188] Meanwhile, based on the privacy mode, when the data switching element (SW2) and the second driving switching element (SW4) are turned on, a second driving current (IDb) proportional to the stored power level stored in the storage capacitor (Cst) flows to the second organic light-emitting layer (ODb). Accordingly, the second organic light-emitting layer (ODb) performs a light-emitting operation.

[0189] Meanwhile, the first organic light-emitting layer (ODa) and the second organic light-emitting layer (ODb) each include an emission layer (EML) corresponding to a subpixel, and may include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL), and may also include a hole blocking layer.

[0190] Meanwhile, in the drawing, the scan switching element (SW1), the data switching element (SW2), and the driving switching element (SW3) are exemplified as p-type MOSFETs, but n-type MOSFETs, or other switching elements such as JFETs, IGBTs, or SICs may also be used.

[0191] Meanwhile, a pixel is a hold-type element that continues to emit light in an organic light-emitting layer (ODa) after a scan signal is applied during a unit display period, specifically, during a unit frame.

[0192] Meanwhile, the sub-pixel circuit (CRTm) in the drawing is driven by an active matrix method.

[0193] FIG. 5d illustrates another example of a circuit of a sub-pixel within a pixel of the panel of FIG. 5a or FIG. 5b.

[0194] Referring to the drawing, the organic light-emitting sub-pixel circuit (CRTm) may be of a passive type and may include a first organic light-emitting diode (ODa) and a second organic light-emitting diode (ODb) without a separate switching element.

[0195] As shown in the drawing, the anode of the first organic light-emitting diode (ODa) is connected to the first data line (Data line a), so that a data signal (Vdata a) can be input, and the cathode of the first organic light-emitting diode (ODa) is connected to the scan line, so that a scan signal (Vscan) can be input.

[0196] Meanwhile, the first organic light-emitting diode (ODa) can emit light or not emit light based on a plurality of sub-frames based on a passive matrix method.

[0197] Meanwhile, the anode of the second organic light-emitting diode (ODb) is connected to the second data line (Data line b), so that a data signal (Vdata b) can be input, and the cathode of the second organic light-emitting diode (ODb) is connected to the scan line, so that a scan signal (Vscan) can be input.

[0198] Meanwhile, the first organic light-emitting diode (ODa) may be placed within a public pixel (PL), and the second organic light-emitting diode (ODb) may be placed within a privacy pixel (RL).

[0199] Meanwhile, the second organic light emitting diode (ODb) can emit light or not emit light based on a plurality of sub-frames based on a passive matrix method.

[0200] Meanwhile, the first organic light-emitting diode (ODa) may be placed within a public pixel (PL), and the second organic light-emitting diode (ODb) may be placed within a privacy pixel (RL).

[0201] Meanwhile, unlike the drawing, the anode of the first organic light-emitting diode (ODa) and the second organic light-emitting diode (ODb) may be connected to a scan line, so that a scan signal (Vscan) may be input, the cathode of the first organic light-emitting diode (ODa) may be connected to a first data line, and the cathode of the second organic light-emitting diode (ODb) may be connected to a second data line.

[0202] Meanwhile, the sub-pixel circuit (CRTm) in the drawing is driven by a passive matrix method.

[0203] FIGS. 6A to 7E are diagrams illustrating a pixel structure and operation according to one embodiment of the present disclosure.

[0204] Figure 6a illustrates an example of the operation of a public pixel (PL) and a privacy pixel (RL) within a pixel.

[0205] Referring to the drawing, a pixel (PXL) in an organic light-emitting panel (210) according to one embodiment of the present disclosure includes a public pixel (PL) and a privacy pixel (RL).

[0206] Meanwhile, the public pixel (PL) may include a red public pixel (Rm), a green public pixel (Gm), and a blue public pixel (Bm).

[0207] Meanwhile, the privacy pixel (RL) may include a red privacy pixel (Rs), a green privacy pixel (Gs), and a blue privacy pixel (Bs).

[0208] Meanwhile, the size of the public pixel (PL) may be larger than the size of the privacy pixel (RL). Accordingly, the viewing angles of the public pixel and the privacy pixel of the organic light-emitting panel (210) may be different.

[0209] Meanwhile, the viewing angle of light output from a public pixel (PL) may be greater than the viewing angle of light output from a privacy pixel (RL). Accordingly, the viewing angles of the public pixel and the privacy pixel of the organic light-emitting panel (210) may be different.

[0210] In the drawing, it is illustrated that all of the red public pixels (Rm), green public pixels (Gm), and blue public pixels (Bm) within the public pixels (PL) emit light, and all of the red privacy pixels (Rs), green privacy pixels (Gs), and blue privacy pixels (Bs) within the privacy pixels (RL) emit light.

[0211] For example, both the first organic light-emitting diode (ODa) and the second organic light-emitting diode (ODb) of FIG. 5c or FIG. 5d can emit light.

[0212] Accordingly, the organic light-emitting panel (210) according to one embodiment of the present disclosure can emit light with the widest viewing angle and brightness.

[0213] Figure 6b illustrates another example of the operation of public pixels (PL) and privacy pixels (RL) within a pixel.

[0214] Referring to the drawing, based on the public mode, only the public pixel (PL) can emit light, and the privacy pixel (RL) can not emit light.

[0215] In the drawing, based on the public mode, the red public pixel (Rm), the green public pixel (Gm), and the blue public pixel (Bm) within the public pixel (PL) all emit light, and the red privacy pixel (Rs), the green privacy pixel (Gs), and the blue privacy pixel (Bs) within the privacy pixel (RL) all do not emit light.

[0216] For example, the first organic light-emitting diode (ODa) of FIG. 5c or FIG. 5d may emit light, and the second organic light-emitting diode (ODb) may not emit light.

[0217] Accordingly, the organic light-emitting panel (210) according to one embodiment of the present disclosure can emit light at a first range of wide viewing angle and a first brightness based on a public mode.

[0218] Figure 6c illustrates another example of the operation of public pixels (PL) and privacy pixels (RL) within a pixel.

[0219] Referring to the drawing, based on the privacy mode, only the public pixel (PL) can emit light, and the privacy pixel (RL) can not emit light.

[0220] In the drawing, based on the privacy mode, the red public pixel (Rm), the green public pixel (Gm), and the blue public pixel (Bm) within the public pixel (PL) are all non-emissive, and the red privacy pixel (Rs), the green privacy pixel (Gs), and the blue privacy pixel (Bs) within the privacy pixel (RL) are all emissive.

[0221] For example, the first organic light-emitting diode (ODa) of FIG. 5c or FIG. 5d may not emit light, and the second organic light-emitting diode (ODb) may emit light.

[0222] Accordingly, the organic light-emitting panel (210) according to one embodiment of the present disclosure can emit light at a second range of a wide viewing angle smaller than the first range and at a second brightness lower than the first brightness, based on the privacy mode.

[0223] FIG. 7a illustrates that a public pixel (PL) and a privacy pixel (RL) emit light corresponding to FIG. 6a.

[0225] Meanwhile, the light-emitting layer (730) may include a red public light-emitting layer, a green public light-emitting layer, and a blue public light-emitting layer corresponding to a public pixel (PL), and a red privacy light-emitting layer, a green privacy light-emitting layer, and a blue privacy light-emitting layer corresponding to a privacy pixel (RL).

[0226] In the drawing, it is exemplified that a red public emitting layer and a red privacy emitting layer are adjacent, a green public emitting layer and a green privacy emitting layer are adjacent, and a blue public emitting layer and a blue privacy emitting layer are adjacent.

[0227] Meanwhile, unlike the drawing, one may, but is not limited to, space the red public emitting layer and the red privacy emitting layer, space the green public emitting layer and the green privacy emitting layer, and space the blue public emitting layer and the blue privacy emitting layer.

[0228] Meanwhile, when both the public pixel (PL) and the privacy pixel (RL) emit light, the red public emission layer, the green public emission layer, the blue public emission layer, the red privacy emission layer, the green privacy emission layer, and the blue privacy emission layer can all emit light, as shown in the drawing.

[0229] Fig. 7b illustrates that only the public pixel (PL) emits light, corresponding to Fig. 6b.

[0230] Referring to the drawing, when only the public pixel (PL) emits light and the privacy pixel (RL) does not emit light, the red public light-emitting layer, the green public light-emitting layer, and the blue public light-emitting layer emit light, and the red privacy light-emitting layer, the green privacy light-emitting layer, and the blue privacy light-emitting layer do not emit light.

[0231] Accordingly, the organic light-emitting panel (210) can emit light at a first range of wide viewing angle and a first brightness.

[0232] Fig. 7c illustrates that only the privacy pixel (RL) emits light, corresponding to Fig. 6c.

[0233] Referring to the drawing, when the public pixel (PL) is non-emissive and only the privacy pixel (RL) is emissive, the red public emitting layer, the green public emitting layer, and the blue public emitting layer are non-emissive, and the red privacy emitting layer, the green privacy emitting layer, and the blue privacy emitting layer can emit light.

[0234] Accordingly, the organic light-emitting panel (210) can emit light at a second range of a wide viewing angle smaller than the first range and at a second brightness lower than the first brightness.

[0235] Figure 7d illustrates the wide viewing angle in the public mode of Figure 7b.

[0236] Referring to the drawing, when an organic light-emitting panel (210) having light-emitting pixels (PXL) including public pixels (PL) and privacy pixels (RL) operates in public mode, only the public pixels (PL) emit light, and the privacy pixels (RL) do not emit light.

[0237] Accordingly, as shown in the drawing, the organic light-emitting panel (210) can emit light at a wide viewing angle of the first range.

[0238] Figure 7e illustrates the wide viewing angle in the privacy mode of Figure 7b.

[0239] Referring to the drawing, when an organic light-emitting panel (210) having light-emitting pixels (PXL) including public pixels (PL) and privacy pixels (RL) operates in privacy mode, the public pixels (PL) do not emit light and only the privacy pixels (RL) emit light.

[0240] Accordingly, as shown in the drawing, the organic light-emitting panel (210) can emit light with a wide viewing angle of a second range that is smaller than the first range.

[0245] Meanwhile, the signal processing device (170) can be controlled to display a cluster image such as vehicle speed information in the first area (Ar1), a map image in the second area (Ar2), and a content image in the third area (Ar3).

[0246] Meanwhile, the signal processing device (170) can control only the first region (Ar1) to be turned on, and the second region (Ar2) and the third region (Ar3) to be turned off.

[0247] Meanwhile, the signal processing device (170) can control only the first region (Ar1) and the second region (Ar2) to be turned on, and the third region (Ar3) to be turned off.

[0248] Meanwhile, the signal processing device (170) can vary the size of the second region (Ar2) or the third region (Ar3). This is described with reference to FIGS. 8b and 8c.

[0251] For example, the signal processing device (170) can vary the size of the second area (Ar2b) or the third area (Ar3b) based on the display content.

[0252] In the drawing, compared to FIG. 8a, the size of the second region (Ar2b) is enlarged and the size of the third region (Ar3b) is reduced.

[0253] That is, compared to Fig. 8a, the second boundary (BLbb), which is the boundary between the second region (Ar2b) and the third region (Ar3b), can be moved to the right. Accordingly, the amount of information displayed in the second region (Ar2b) can be increased.

[0257] FIGS. 9A to 9F are drawings for reference in explaining various operations of a display according to one embodiment of the present disclosure.

[0258] FIG. 9a illustrates, corresponding to FIG. 8a, that three areas within the display (180 m) operate by dividing them into a public area and a privacy area, respectively.

[0259] Referring to the drawing, the signal processing device (170) can control the cluster area, which is the first area (Ar1) of the display (180m), to operate as a public area, the information display area, which is the second area (Ar2) of the display (180m), to operate as a public area, and the auxiliary seat area, which is the third area (Ar3) of the display (180m), to operate as a privacy area. Accordingly, the display can be operated as a switchable privacy display.

[0260] That is, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2) to operate in public mode, and control the third region (Ar3) to operate in privacy mode.

[0261] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the second region (Ar2), only the public pixel (PL) emits light.

[0262] Meanwhile, among the public pixels (PL) and privacy pixels (RL) in the third area (Ar3), only the privacy pixels (RL) emit light.

[0263] Accordingly, the images displayed in the first area (Ar1) and the second area (Ar2) can be viewed from the driver's seat, but the images displayed in the third area (Ar3) cannot be viewed from the driver's seat, and can only be viewed from the passenger seat.

[0264] Accordingly, the display (180m) operates as a switchable privacy display.

[0265] FIG. 9b illustrates, corresponding to FIG. 8b, that three areas within the display (180m) operate by dividing them into a public area and a privacy area, respectively.

[0266] Referring to the drawing, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2b) to operate in a public mode, and control the third region (Ar3b) to operate in a privacy mode.

[0267] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the second region (Ar2b), only the public pixel (PL) emits light, and among the public pixels (PL) and privacy pixels (RL) in the third region (Ar3b), only the privacy pixel (RL) emits light.

[0268] Fig. 9c corresponds to Fig. 8c and illustrates that three areas within the display (180m) are operated by dividing them into a public area and a privacy area, respectively.

[0269] Referring to the drawing, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2c) to operate in a public mode, and control the third region (Ar3c) to operate in a privacy mode.

[0270] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the second region (Ar2c), only the public pixel (PL) emits light, and among the public pixels (PL) and privacy pixels (RL) in the third region (Ar3c), only the privacy pixel (RL) emits light.

[0271] Meanwhile, with reference to FIGS. 9B and 9C, the signal processing device (170) can vary the size of the public area or the privacy area based on the image display mode or vehicle speed. Accordingly, image display corresponding to the image display mode or vehicle speed becomes possible.

[0272] FIG. 9d illustrates, corresponding to FIG. 8a, that three areas within the display (180m) operate by dividing them into a public area and a privacy area, respectively.

[0273] Referring to the drawing, the signal processing device (170) can control the cluster area, which is the first area (Ar1) of the display (180m), to operate as a privacy area, the information display area, which is the second area (Ar2) of the display (180m), to operate as a public area, and the auxiliary seat area, which is the third area (Ar3) of the display (180m), to operate as a privacy area. Accordingly, the display can be operated as a switchable privacy display.

[0274] That is, the signal processing device (170) can control the second region (Ar2) to operate in a public mode and control the first region (Ar1) and the third region (Ar3) to operate in a privacy mode.

[0275] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the second region (Ar2), only the public pixel (PL) emits light, and among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the third region (Ar3), only the privacy pixel (RL) emits light.

[0276] That is, the image displayed in the first area (Ar1) can only be viewed from the driver's seat and cannot be viewed from the passenger seat.

[0277] Meanwhile, the image displayed in the second area (Ar2) can be viewed from the driver's seat, and the image displayed in the third area (Ar3) cannot be viewed from the driver's seat, but can only be viewed from the passenger seat.

[0278] FIG. 9e illustrates, corresponding to FIG. 8b, that three areas within the display (180m) operate by dividing them into a public area and a privacy area, respectively.

[0279] Referring to the drawing, the signal processing device (170) can control the second region (Ar2b) to operate in a public mode and control the first region (Ar1) and the third region (Ar3b) to operate in a privacy mode.

[0280] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the second region (Ar2b), only the public pixels (PL) emit light, and among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the third region (Ar3b), only the privacy pixels (RL) emit light.

[0281] FIG. 9f illustrates, corresponding to FIG. 8c, that three areas within the display (180m) operate by dividing them into a public area and a privacy area, respectively.

[0282] Referring to the drawing, the signal processing device (170) can control the second region (Ar2c) to operate in a public mode and control the first region (Ar1) and the third region (Ar3c) to operate in a privacy mode.

[0283] Accordingly, among the public pixels (PL) and privacy pixels (RL) in the second region (Ar2c), only the public pixels (PL) emit light, and among the public pixels (PL) and privacy pixels (RL) in the first region (Ar1) and the third region (Ar3c), only the privacy pixels (RL) emit light.

[0284] FIG. 10A is an example of an operation flowchart of a vehicle display device according to one embodiment of the present disclosure.

[0285] Referring to the drawing, a signal processing device (170) according to one embodiment of the present disclosure can be controlled to display a public area and a privacy area separately within a display (180m) (S1010).

[0286] For example, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2) to operate in public mode, and control the third region (Ar3) to operate in privacy mode, as shown in FIG. 9a.

[0287] As another example, the signal processing device (170) can control the second region (Ar2) to operate in a public mode, and control the first region (Ar1) and the third region (Ar3) to operate in a privacy mode, as shown in FIG. 9d.

[0288] Next, the signal processing device (170) can control the boundary area, which is the boundary between the public area and the privacy area, to be moved (S1015).

[0289] For example, as shown in Fig. 9a, when the first region (Ar1) and the second region (Ar2) operate in public mode and the third region (Ar3) operates in privacy mode, the possibility of deterioration occurring near the second boundary (BLb), which is the boundary between the second region (Ar2) and the third region (Ar3), increases.

[0290] Accordingly, in the present disclosure, regardless of deterioration judgment or brightness difference judgment, etc., the boundary area or boundary is controlled to move sequentially.

[0291] For example, a signal processing device (170) according to one embodiment of the present disclosure can control a boundary area to sequentially move toward a public area and then toward a privacy area.

[0292] That is, the signal processing device (170) can control the second boundary (BLb), which is the boundary between the second area (Ar2) and the third area (Ar3) in FIG. 9a, to sequentially move in the direction of the second area (Ar2), which is the public area direction, and then in the direction of the third area (Ar3), which is the privacy area direction.

[0293] In addition, the signal processing device (170) can control the movement of this boundary region to be repeated. Accordingly, deterioration near the second boundary (BLb) can be prevented.

[0294] As another example, a signal processing device (170) according to one embodiment of the present disclosure can control the boundary area to sequentially move toward the privacy area and then toward the public area.

[0295] That is, the signal processing device (170) can control the second boundary (BLb), which is the boundary between the second area (Ar2) and the third area (Ar3) in FIG. 9a, to sequentially move toward the third area (Ar3), which is the privacy area direction, and then toward the second area (Ar2), which is the public area direction. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel can be reduced.

[0296] Meanwhile, as shown in FIG. 9d, when the second region (Ar2) operates in public mode and the first region (Ar1) operates in privacy mode, the possibility of deterioration occurring near the first boundary (BLa), which is the boundary between the first region (Ar1) and the second region (Ar2), increases.

[0297] Accordingly, in the present disclosure, regardless of deterioration judgment or brightness difference judgment, etc., the boundary area or boundary is controlled to move sequentially.

[0298] That is, the signal processing device (170) can control the first boundary (BLa), which is the boundary between the first area (Ar1) and the second area (Ar2) in FIG. 9d, to sequentially move in the direction of the second area (Ar2), which is the public area direction, and then move in the direction of the first area (Ar1), which is the privacy area direction.

[0299] In addition, the signal processing device (170) can control the movement of this boundary region to be repeated. Accordingly, deterioration near the second boundary (BLb) can be prevented.

[0300] As another example, a signal processing device (170) according to one embodiment of the present disclosure can control the boundary area to sequentially move toward the privacy area and then toward the public area.

[0301] That is, the signal processing device (170) can control the first boundary (BLa), which is the boundary between the first region (Ar1) and the second region (Ar2) in FIG. 9d, to sequentially move in the direction of the first region (Ar1), which is the privacy region, and then in the direction of the second region (Ar2), which is the public region. Accordingly, deterioration of the boundary region of the organic light-emitting panel can be reduced.

[0302] FIG. 10b is another example of an operation flowchart of a vehicle display device according to one embodiment of the present disclosure.

[0303] Referring to the drawing, a signal processing device (170) according to one embodiment of the present disclosure can be controlled to display a public area and a privacy area separately within a display (180m) (S1010).

[0304] For example, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2) to operate in public mode, and control the third region (Ar3) to operate in privacy mode, as shown in FIG. 9a.

[0305] As another example, the signal processing device (170) can control the second region (Ar2) to operate in a public mode and control the first region (Ar1) and the third region (Ar3) to operate in a privacy mode.

[0306] Next, the signal processing device (170) can determine whether degradation occurs in the boundary area, which is the boundary between the public area and the privacy area (S1020).

[0307] For example, when the signal processing device (170) controls the first region (Ar1) and the second region (Ar2) to operate in a public mode and the third region (Ar3) to operate in a privacy mode, as shown in FIG. 9a, it can determine whether degradation occurs near the second boundary (BLb), which is the boundary between the second region (Ar2) and the third region (Ar3).

[0308] Specifically, the signal processing device (170), as shown in FIG. 9a, controls the first region (Ar1) and the second region (Ar2) to operate in a public mode, and when the third region (Ar3) operates in a privacy mode, calculates the accumulated deterioration amount of the boundary region (Arma), which is a part of the second region (Ar2) adjacent to the second boundary (BLb), and if the accumulated deterioration amount is greater than a set value, it can be determined as deterioration.

[0309] At this time, the signal processing device (170) can calculate the accumulated deterioration amount based on the accumulated brightness level of the boundary area (Arma).

[0310] Alternatively, the signal processing device (170) can calculate the accumulated deterioration amount based on the accumulated brightness level and temperature information of the boundary area (Arma).

[0311] Meanwhile, the signal processing device (170) can perform a deterioration compensation mode (S1030) when the boundary area (Arma) is determined to be deteriorated in step 1020 (S1020).

[0312] That is, the signal processing device (170) can perform a deterioration compensation mode for an area around the boundary area when the boundary area (Arma) between the public area based on the public pixel (PL) and the privacy area based on the privacy pixel (RL) is deteriorated.

[0313] For example, the signal processing device (170) can control the brightness level of the boundary area (Arma) to be lowered, as an example of a degradation compensation mode.

[0314] Specifically, the signal processing device (170) can control the brightness level of the boundary area (Arma) to be lowered to an output brightness level lower than the input brightness level, as an example of a degradation compensation mode.

[0315] Meanwhile, the signal processing device (170) can control a portion of an area within a public area to be converted into a privacy area, as another example of a degradation compensation mode.

[0316] For example, the signal processing device (170) can control a boundary area (Arma), which is a part of a public area, to be converted into a privacy area.

[0317] That is, since the privacy area has a narrower optical viewing angle and lower luminance than the public area, degradation compensation can be performed. Accordingly, degradation in the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0318] Ultimately, the signal processing device (170) according to one embodiment of the present disclosure controls a portion of the public area to be converted into a privacy area when the boundary area between the public area based on public pixels (PL) and the privacy area based on privacy pixels (RL) deteriorates. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0319] Meanwhile, the signal processing device (170) can control the area transitioning from the public area to the privacy area to sequentially increase when the boundary area deteriorates. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0320] Meanwhile, the signal processing device (170) can vary the size of the area transitioning from the public area to the privacy area based on the accumulated deterioration amount of the boundary display area.

[0321] For example, the signal processing device (170) can control the size of the area transitioning from the public area to the privacy area to increase as the accumulated deterioration amount of the boundary display area increases. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0322] Next, the signal processing device (170) determines whether degradation occurs within the public area, rather than the boundary area between the public area and the privacy area (S1035).

[0323] For example, the signal processing device (170) can determine deterioration within the first area (Ar1), which operates as a public area.

[0324] As another example, the signal processing device (170) can determine deterioration within the second area (Ar2), which operates as a public area.

[0325] The signal processing device (170) can be controlled to perform a second degradation compensation mode when degradation occurs in the first area (Ar1) or the second area (Ar2), which is a public area (S1040).

[0326] That is, the signal processing device (170) can perform the second degradation compensation mode when a second portion of the public area is degraded.

[0327] For example, the signal processing device (170) can vary the brightness of a second partial area when performing the second degradation compensation mode.

[0328] Specifically, the signal processing device (170) can control the brightness of a second partial area to be lowered when performing the second degradation compensation mode.

[0329] At this time, the brightness level due to brightness compensation when performing the second degradation compensation mode may be greater than the brightness level due to degradation compensation in step 1030.

[0330] That is, the signal processing device (170) can control the degradation compensation to be smaller than the degradation compensation in step 1030 when performing the second degradation compensation mode.

[0331] For example, since degradation is more pronounced in the boundary region, it is desirable to reduce the amount of compensation when performing the second degradation compensation mode. This allows for reduced degradation in the second portion of the public domain.

[0332] Meanwhile, the signal processing device (170) can control the second partial area to be converted into a privacy area when performing the second degradation compensation mode. Accordingly, degradation of the second partial area within the public area can be reduced.

[0333] Meanwhile, the signal processing device (170) can control the size of the second partial area converted into a privacy area when performing the second degradation compensation mode to be smaller than the size of the boundary area converted into a privacy area during degradation compensation in step 1030. Accordingly, degradation of the second partial area within the public area can be reduced.

[0334] FIG. 10c is another example of an operation flowchart of a vehicle display device according to one embodiment of the present disclosure.

[0335] Referring to the drawing, a signal processing device (170) according to one embodiment of the present disclosure can be controlled to display a public area and a privacy area separately within a display (180m) (S1010).

[0336] For example, the signal processing device (170) can control the first region (Ar1) and the second region (Ar2) to operate in public mode, and control the third region (Ar3) to operate in privacy mode, as shown in FIG. 9a.

[0337] Next, the signal processing device (170) can determine whether the difference in brightness between the public area and the privacy area is greater than a predetermined value (S1021).

[0338] For example, when the signal processing device (170) controls the first region (Ar1) and the second region (Ar2) to operate in a public mode and the third region (Ar3) to operate in a privacy mode, as shown in FIG. 9a, it can determine whether the difference in brightness is greater than a predetermined value near the second boundary (BLb), which is the boundary between the second region (Ar2) and the third region (Ar3).

[0339] Specifically, when the signal processing device (170) controls the first region (Ar1) and the second region (Ar2) to operate in a public mode and the third region (Ar3) to operate in a privacy mode, as shown in FIG. 9a, it can determine whether the difference between the luminance of the boundary region (Arma), which is a part of the second region (Ar2) adjacent to the second boundary (BLb), and the luminance of a part of the third region (Ar3) adjacent to the second boundary (BLb) is greater than or equal to a predetermined value.

[0340] For example, the signal processing device (170) can determine whether the brightness level of a boundary area (Arma), which is a part of the second area (Ar2) adjacent to the second boundary (BLb), is higher and whether the brightness difference near the second boundary (BLb) is greater than a predetermined value.

[0341] Meanwhile, in step 1021 (S1021), if the difference in brightness between the public area and the private area is determined to be greater than a predetermined value, the signal processing device (170) controls a portion of the public area to be converted to a private area (S1031).

[0342] For example, the signal processing device (170) can control a boundary area (Arma), which is a part of a public area, to be converted into a privacy area.

[0343] That is, since the privacy area has a narrower optical viewing angle and lower brightness than the public area, the difference in brightness in the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0344] Meanwhile, the signal processing device (170) can control the area transitioning from the public area to the private area to sequentially increase when the difference in luminance between the public area and the private area is greater than a predetermined value. Accordingly, the difference in luminance in the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0345] Meanwhile, the signal processing device (170) can control the size of the area transitioning from the public area to the privacy area to be variable based on the level of the brightness difference between the public area and the privacy area.

[0346] For example, the signal processing device (170) can control the size of the area transitioning from the public area to the privacy area to increase as the difference in luminance between the public area and the privacy area increases. Accordingly, the difference in luminance in the boundary area of ​​the organic light-emitting panel (210) can be effectively reduced.

[0347] Next, the signal processing device (170) determines whether the brightness difference in some area within the public area, other than the boundary area between the public area and the private area, is greater than or equal to the second predetermined value (S1035).

[0348] For example, the signal processing device (170) can determine whether the luminance difference of some area within the first area (Ar1), which operates as a public area, is greater than or equal to a second predetermined value.

[0349] As another example, the signal processing device (170) can determine whether the luminance difference of some area within the second area (Ar2), which operates as a public area, is greater than or equal to a second predetermined value.

[0350] Meanwhile, the signal processing device (170) can control the luminance difference of a certain area within the first area (Ar1) or the second area (Ar2), which is a public area, to be reduced when the luminance difference of the area is greater than or equal to a second predetermined value (S1040).

[0351] For example, if the luminance difference of some area within the first area (Ar1) or the second area (Ar2) is greater than or equal to the second predetermined value, the signal processing device (170) can control the luminance difference to be reduced by lowering the first luminance level to the second luminance level and lowering the third luminance level to the fourth luminance level, thereby reducing the difference between the first luminance level and the third luminance level to the difference between the second luminance level and the fourth luminance level. Accordingly, the luminance difference in the corresponding area can be reduced.

[0352] Meanwhile, if the luminance difference of a portion of a public area, such as the first area (Ar1) or the second area (Ar2), is greater than or equal to a second predetermined value, the signal processing device (170) may control the portion of the public area to be converted into a privacy area, rather than controlling the luminance difference of the corresponding portion to be reduced. Accordingly, the luminance difference of the second portion of the public area can be reduced.

[0353] Ultimately, when combining FIGS. 10b and 10c, the signal processing device (170) controls a portion of an area within the public area to be converted into a privacy area when the boundary area between the public area based on public pixels (PL) and the privacy area based on privacy pixels (RL) is deteriorated or the difference in luminance between the public area and the privacy area is greater than a predetermined value. Accordingly, it is possible to reduce the deterioration or luminance difference in the boundary area of ​​the organic light-emitting panel (210).

[0354] Meanwhile, the signal processing device (170) can control a portion of the second area (Ar2), which is a public area, to be converted into a privacy area when the boundary area between the second area (Ar2), which is a public area, and the third area (Ar3), which is a privacy area, is deteriorated or the difference in brightness between the second area (Ar2) and the third area (Ar3) is greater than a predetermined value. Accordingly, the deterioration or difference in brightness in the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0355] Meanwhile, the signal processing device (170) can control a portion of the second area (Ar2), which is a public area, to be converted into a privacy area when the boundary area between the first area (Ar1), which is a privacy area, and the second area (Ar2), which is a public area, is deteriorated or when the difference in brightness between the first area (Ar2) and the second area (Ar2) is greater than a predetermined value. Accordingly, it is possible to reduce the deterioration or brightness difference in the boundary area of ​​the organic light-emitting panel (210).

[0356] Figures 11 to 12b are drawings referenced in the description of Figures 10a to 10c.

[0357] Figure 11 is a diagram illustrating an example of a transition from a public domain to a private domain.

[0358] Referring to the drawing, Fig. 11 (a) illustrates a public area (Arpa) of four columns and a privacy area (Arya) of two columns.

[0359] The signal processing device (170) may not perform a separate degradation compensation mode when the degradation amount of the public area (Arpa) is '1' and the degradation amount of the privacy area (Arya) is '1'.

[0360] Figure 11 (b) illustrates that the deterioration of the public area (Arpa) of four columns has progressed, and the deterioration amount of the public area (Arpa) is '2' and the deterioration amount of the privacy area (Arya) is '1'.

[0361] In this case, the signal processing device (170) can control the degradation model mode to be performed for the first boundary area (BDa) because the difference between the degradation amount of the public area (Arpa) and the degradation amount of the privacy area (Arya) is '1'.

[0362] For example, the signal processing device (170) can control a part of the public area (Arpa) to be converted into a privacy area in a deterioration model mode.

[0363] That is, the signal processing device (170) can be controlled to have a public area (Arpb) of three columns and a privacy area (Aryb) of three columns, as shown in (c) of FIG. 11.

[0364] (d) of Fig. 11 illustrates that the deterioration of the public area (Arpb) of three columns has progressed further, with the deterioration amount of the public area (Arpb) being '3', the deterioration amount of some areas of the privacy area (Aryb) being '2', and the deterioration amount of the remaining areas being '1'.

[0365] In this case, the signal processing device (170) can control the degradation model mode to be performed for the second boundary area (BDb) because the difference between the degradation amount of the public area (Arpb) and the degradation amount of the privacy area (Aryb) is '1'.

[0366] For example, the signal processing device (170) can control a part of the public area (Arpa) to be converted into a privacy area in a deterioration model mode.

[0367] That is, the signal processing device (170) can be controlled to have a public area (Arpc) of two columns and a privacy area (Aryc) of four columns, as shown in (e) of FIG. 11.

[0368] In this way, the signal processing device (170) can control the area transitioning from the public area to the privacy area to sequentially increase when the boundary area deteriorates. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel (210) can be reduced.

[0369] Meanwhile, in Fig. 11, in response to the operation method of Fig. 10a, the boundary between the public area and the private area is sequentially moved in the left direction toward the public area, but is not limited thereto.

[0370] That is, the signal processing device (170) can control the boundary between the public area and the private area to sequentially move to the left in the direction of the public area and then to the right in the direction of the private area. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel can be reduced.

[0371] Alternatively, unlike FIG. 11, the signal processing device (170) can control the boundary between the public area and the privacy area to sequentially move to the right toward the privacy area and then to the left toward the public area. Accordingly, deterioration of the boundary area of ​​the organic light-emitting panel can be reduced.

[0372] Figure 12a illustrates that the boundary area between the second area (Ar2), which is a public area, and the third area (Ar3), which is a privacy area, is deteriorated.

[0373] Referring to the drawing, (a) of FIG. 12a illustrates a first area (Ar1), a second area (Ar2), and a third area (Ar3) within the display (180m).

[0374] At this time, the first area (Ar1) and the second area (Ar2) may be public areas, and the third area (Ar3) may be a privacy area.

[0375] Meanwhile, when the boundary area (Arma) between the second area (Ar2), which is a public area, and the third area (Ar3), which is a privacy area, is deteriorated, the signal processing device (170) can control a part (Arma) of the second area (Ar2), which is a public area, to be converted into a privacy area, as shown in (b) of FIG. 12a.

[0376] Accordingly, the boundary between the public area and the privacy area is changed to BLb2, which is to the left of BLb.

[0377] Meanwhile, the signal processing device (170) can control the area where the public area is switched to the privacy area to sequentially increase when the boundary area deteriorates.

[0378] That is, the signal processing device (170) can control, in addition to a part (Arma) of the second area (Ar2), another part (Armb) to be converted to a privacy area, as in (c) of FIG. 12a.

[0379] Accordingly, the boundary between the public area and the privacy area is changed to BLb3, which is to the left of BLb2.

[0380] Figure 12b illustrates that the boundary area between the public area, the second area (Ar2), and the privacy area, the first area (Ar1), is deteriorated.

[0381] Referring to the drawing, (a) of FIG. 12b illustrates a first area (Ar1), a second area (Ar2), and a third area (Ar3) within the display (180m).

[0382] At this time, the second area (Ar2) may be a public area, and the first area (Ar1) and the third area (Ar3) may be privacy areas.

[0383] Meanwhile, when the boundary area (Arna) between the second area (Ar2), which is a public area, and the first area (Ar1), which is a privacy area, is deteriorated, the signal processing device (170) can control a part (Arna) of the second area (Ar2), which is a public area, to be converted into a privacy area, as shown in (b) of FIG. 12b.

[0384] Accordingly, the boundary between the public area and the privacy area is changed to BLa2, which is to the right of BLa.

[0385] Meanwhile, the signal processing device (170) can control the area where the public area is switched to the privacy area to sequentially increase when the boundary area deteriorates.

[0386] That is, the signal processing device (170) can control, in addition to a part (Arna) of the second area (Ar2), another part (Arnb) to be converted into a privacy area, as in (c) of Fig. 12b.

[0387] Accordingly, the boundary between the public area and the privacy area is changed to BLa3, which is to the right of BLa2.

[0388] FIG. 13 is an example of an internal block diagram of a vehicle display device according to one embodiment of the present disclosure.

[0389] Referring to the drawings, a vehicle display device (100) according to one embodiment of the present disclosure includes a display (180ma), a signal processing device (170), a memory (140), and a motor driving unit (183).

[0390] The motor driving unit (183) can operate to adjust the height of the organic light-emitting panel (210).

[0391] For example, the motor driving unit (183) can control the height of the organic light-emitting panel (210) to become the first height (hb) when the organic light-emitting panel (210) is in pop-up mode.

[0392] As another example, the motor driving unit (183) can control the height of the organic light-emitting panel (210) to be a second height (ha) that is smaller than the first height (hb) when the organic light-emitting panel (210) is in pop-down mode.

[0393] Meanwhile, a display (180ma) in a vehicle display device (100) according to one embodiment of the present disclosure includes an organic light-emitting panel (210) and a driving control unit (285) that outputs a driving signal to the organic light-emitting panel (210).

[0409] Figures 14a and 14b are drawings referred to in the description of Figure 13.

[0410] FIG. 14a is a drawing showing the front and back of a display in pop-down mode according to an embodiment of the present disclosure.

[0411] Referring to the drawing, the display (180ma) according to the embodiment of the present disclosure can operate in a pop-down mode in which only the first display area (Ara) protrudes on the dashboard (DS), as shown in (a) of FIG. 14a, by the operation of the motor driving unit (183).

[0412] The height of the display (180ma) in pop down mode can be ha.

[0413] At this time, the boundary (BL) of the first display area (Ara) and the second display area (Arb) may be located at the height of the dashboard (DS).

[0414] Meanwhile, as shown in (b) of Fig. 14a, a first temperature detection unit (TSa) and a second temperature detection unit (TSb) may be arranged on the back surface of the display (180ma) or the back surface of the organic light-emitting panel (210).

[0415] A first temperature detection unit (TSa) may be arranged in a first display area (Ara) on the back surface of the display (180ma) or the back surface of the organic light-emitting panel (210), and a second temperature detection unit (TSb) may be arranged in a second display area (Arb) on the back surface of the display (180ma) or the back surface of the organic light-emitting panel (210).

[0416] Meanwhile, a circuit board (SPBa) for arranging a driving control unit (285), etc., is arranged on the lower part of the back surface of the display (180ma) or the back surface of the organic light-emitting panel (210), and a second temperature detection unit (TSb) can be arranged on the circuit board (SPBa).

[0417] Meanwhile, the first temperature detection unit (TSa) is spaced apart from the circuit board (SPBa) and is placed on the upper side of the circuit board (SPBa), and a conductive line (CNa) may be placed between the circuit board (SPBa) and the first temperature detection unit (TSa) for connection to the circuit board (SPBa).

[0418] Meanwhile, the first temperature detection unit (TSa) may be placed in the center area of ​​the first display area (Ara), and the second temperature detection unit (TSb) may be placed in the right area, not the center area, of the second display area (Arb).

[0419] Meanwhile, in the pop-down mode, the circuit board (SPBa) and the second temperature detection unit (TSb) may be placed at the bottom of the dashboard (DS) and may not be exposed.

[0420] Meanwhile, in the pop-down mode, the circuit board (SPBa) and the second temperature detection unit (TSb), etc., are disposed at the lower part of the dashboard (DS) and are not exposed, so heat exchange, etc., is weaker than the first temperature detection unit (TSa) disposed at the upper part of the dashboard (DS), and therefore the temperature of the circuit board (SPBa) and the second temperature detection unit (TSb), etc., may become higher than the temperature of the first temperature detection unit (TSa).

[0421] FIG. 14b is a drawing showing the front and back of a display in pop-up mode according to an embodiment of the present disclosure.

[0422] Referring to the drawing, the display (180ma) according to the embodiment of the present disclosure can operate in a pop-up mode in which the first display area (Ara) and the second display area (Arb) protrude together on the dashboard (DS), as shown in (a) of FIG. 14b, by the operation of the motor driving unit (183).

[0423] The height of the display (180ma) in pop-up mode may be hb higher than ha in Fig. 14a.

[0424] At this time, the boundary (BL) of the first display area (Ara) and the second display area (Arb) can be exposed at a position higher than the dashboard (DS).

[0425] Meanwhile, as shown in (b) of FIG. 14b, a first temperature detection unit (TSa) and a second temperature detection unit (TSb) may be arranged on the back surface of the display (180ma) or the back surface of the organic light-emitting panel (210).

[0426] Meanwhile, in pop-up mode, the circuit board (SPBa) and the second temperature detection unit (TSb) can be at least partially exposed to the upper part of the dashboard (DS).

[0427] Meanwhile, in pop-up mode, at least a portion of the circuit board (SPBa) and the second temperature detection unit (TSb) are exposed, so that heat exchange is performed more smoothly than in the palm-down mode, and the temperature can be lowered.

[0428] FIG. 15 is another example of an operation flowchart of a vehicle display device according to one embodiment of the present disclosure.

[0429] Referring to the drawing, a signal processing device (170) or a driving control unit (285) according to one embodiment of the present disclosure determines whether the display (180ma) is in pop-down mode (S1505).

[0430] In the pop-down mode, as shown in Fig. 14a, the height of the display panel (180m) is the second height (ha), and among the first display area (Ara) and the second display area (Arb), only the first display area (Ara) can protrude.

[0431] Meanwhile, if it is not a pop-up mode, it may be a pop-up mode as in Fig. 14b.

[0432] Meanwhile, in the case of pop-down mode, the signal processing device (170) or the driving control unit (285) determines whether the temperature difference between the first display area (Ara) and the second display area (Arb) is greater than or equal to a reference value (S1510).

[0433] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the brightness of the first display area (Ara) or the second display area (Arb) to be variable when the temperature difference between the first display area (Ara) and the second display area (Arb) is greater than or equal to a reference value (S1515).

[0434] For example, the signal processing device (170) or the driving control unit (285) can control the brightness of the first display area (Ara) to be lowered when the temperature difference between the first display area (Ara) and the second display area (Arb) is greater than a reference value and the temperature of the first display area (Ara) is higher than the temperature of the second display area (Arb). Accordingly, it is possible to adaptively reduce deterioration based on the temperature of each area of ​​the organic light-emitting panel (210).

[0435] As another example, the signal processing device (170) or the driving control unit (285) can control the brightness of the second display area (Arb) to be lowered or the brightness of the first display area (Ara) to be lowered when the temperature difference between the first display area (Ara) and the second display area (Arb) is greater than a reference value and the temperature of the second display area (Arb) is higher than the temperature of the first display area (Ara). Accordingly, it is possible to adaptively reduce deterioration based on the temperature of each area of ​​the organic light-emitting panel (210).

[0436] Meanwhile, the signal processing device (170) or the driving control unit (285) may perform the first degradation compensation mode based on the first detection temperature or the second detection temperature when the difference between the first detection temperature and the second detection temperature is less than the reference value.

[0437] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the second degradation compensation mode to be performed when the difference between the first detection temperature and the second detection temperature is greater than or equal to the reference value and within the allowable value.

[0438] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the display (180ma) or the organic light-emitting panel (210) to be turned off when the difference between the first detection temperature and the second detection temperature is greater than or equal to the reference value and exceeds the allowable value. Accordingly, the panel can be protected.

[0439] Meanwhile, the signal processing device (170) or the driving control unit (285) can be controlled to operate in a state in which the first display area (Ara) is in an on mode and the second display area (Arb) is in an off mode displayed at the first brightness level in the pop-down mode.

[0440] At this time, the signal processing device (170) or the driving control unit (285) can perform the first degradation mode when the difference between the first detection temperature and the second detection temperature is less than the reference value in a state where the first display area (Ara) is in the on mode and the second display area (Arb) is in the off mode displayed at the first brightness level in the pop-down mode.

[0441] Meanwhile, the signal processing device (170) or the driving control unit (285) can perform the second degradation mode when the difference between the first detection temperature and the second detection temperature is greater than or equal to a reference value in a state where the first display area (Ara) is in the on mode and the second display area (Arb) is in the off mode displayed at the first brightness level in the pop-down mode.

[0442] In particular, the signal processing device (170) or the driving control unit (285) can perform the second degradation compensation mode when, in the pop-down mode, the difference between the first detection temperature and the second detection temperature is greater than or equal to a reference value and the first detection temperature is greater than the second detection temperature.

[0443] Meanwhile, the signal processing device (170) or the driving control unit (285) can vary the size of the luminance compensation value in the second degradation compensation mode, unlike the first degradation compensation mode, by further considering the difference between the first detection temperature and the second detection temperature.

[0444] For example, in the second deterioration compensation mode, the signal processing device (170) or the driving control unit (285) can control the brightness compensation value to increase in size as the difference between the first detection temperature and the second detection temperature is greater than or equal to a reference value and the difference increases. Accordingly, in the second deterioration compensation mode, deterioration can be reduced based on the temperature difference in the area.

[0445] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the brightness compensation value to increase in size when the difference between the first detection temperature and the second detection temperature is greater than or equal to a reference value in the second deterioration compensation mode and the first detection temperature or the second detection temperature increases. Accordingly, deterioration can be reduced based on the detection temperature of the area in the second deterioration compensation mode.

[0446] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the brightness compensation value to become larger in the second deterioration compensation mode when the difference between the first detection temperature and the second detection temperature is greater than or equal to a reference value and the accumulated deterioration amount of the first display area (Ara) or the second display area (Arb) increases. Accordingly, in the second deterioration compensation mode, deterioration can be reduced based on the accumulated deterioration amount of the display area.

[0447] Figure 16a illustrates that luminance gradient processing is performed in a third area including a boundary (BL) between a first display area (Ara) and a second display area (Arb).

[0448] Referring to the drawing, the signal processing device (170) or the driving control unit (285) may not perform any special processing near the boundary (BL) between the first display area (Ara) and the second display area (Arb) in the pop-down mode of the display (180ma) as in (a) of FIG. 16a.

[0449] Meanwhile, in the pop-up mode, the visibility of the boundary (BL) portion deteriorates due to the difference in brightness between the first display area (Ara) and the second display area (Arb).

[0450] To solve this, the signal processing device (170) or the driving control unit (285) according to the embodiment of the present disclosure can perform luminance gradation processing on a third area including a boundary (BL) between the first display area (Ara) and the second display area (Arb) when performing the first deterioration compensation mode or the second deterioration compensation mode.

[0451] That is, the signal processing device (170) or the driving control unit (285) according to the embodiment of the present disclosure can display an image (Imc) on which luminance gradient processing has been performed in a third area including a boundary (BL) between the first display area (Ara) and the second display area (Arb), as shown in (b) of FIG. 16a.

[0452] Meanwhile, the luminance level of the image (Imc) on which luminance gradient processing has been performed may be a value between the luminance level of the image (Ima) of the first display area (Ara) and the luminance level of the image (Imb) of the second display area (Arb). Accordingly, the visibility of the boundary (BL) portion can be improved by the luminance difference between the first display area (Ara) and the second display area (Arb).

[0453] Figure 16b is a drawing illustrating various methods for improving visibility of the area boundary of a display (180 ma).

[0454] Referring to the drawing, as in (a) of FIG. 16b, a first image (Ima) may be displayed in a first display area (Ara) of a display (180ma), and a second image (Imb) may be displayed in a second display area (Arb).

[0455] Meanwhile, the signal processing device (170) or the driving control unit (285) can control, as shown in (b) of Fig. 16b, to display a third image (Imk) having a luminance level between the luminance level of the first image (Ima) and the luminance level of the second image (Imb) at the boundary (BL) between the first display area (Ara) and the second display area (Arb). Accordingly, the visibility of the boundary (BL) between the first display area (Ara) and the second display area (Arb) can be improved.

[0456] Meanwhile, the signal processing device (170) or the driving control unit (285) can control the display of a home button or a fourth image (Imm) providing various information on the boundary (BL) between the first display area (Ara) and the second display area (Arb), as shown in (c) of Fig. 16b. Accordingly, the visibility of the boundary (BL) between the first display area (Ara) and the second display area (Arb) can be improved.

[0457] FIGS. 17a to 17c are drawings illustrating various gradient processing for a boundary (BL) portion between a first display area (Ara) and a second display area (Arb) of the display (180ma) of FIG. 16a.

[0458] If the upper point of the display (180ma) is A and the lower point of the display (180ma) is B, FIGS. 17a to 17c illustrate the brightness level, etc. between the lower and upper points of the display (180ma).

[0459] Figure 17a (a) illustrates that gradient processing is performed in the direction from the boundary (BL) to the lower point (B) of the display (180ma).

[0460] As shown in (b) of Fig. 17a, when the luminance level of the first display area (Ara) is Lma1, which is greater than the luminance level of the second display area (Arb), Lma2, the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVaa) in which the luminance level decreases from the boundary (BL) toward the lower point (B) of the display (180ma). Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0461] As in (c) of Fig. 17a, when the luminance level of the first display area (Ara) is Lma3, which is lower than the luminance level of the second display area (Arb), Lma2, the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVab) in which the luminance level increases from the boundary (BL) toward the lower point (B) of the display (180ma). Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0462] Figure 17b (a) illustrates that gradient processing is performed at the boundary (BL).

[0463] As shown in (b) of Fig. 17b, when the luminance level of the first display area (Ara) is Lmb1, which is greater than the luminance level Lma2 of the second display area (Arb), the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVba) in which the luminance level increases from the lower point (B) of the display (180ma) to the upper point (A) of the display (180ma) with the boundary (BL) as the center. Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0464] As in (c) of Fig. 17b, when the luminance level of the first display area (Ara) is Lmb2, which is lower than the luminance level Lma2 of the second display area (Arb), the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVbb) in which the luminance level decreases from the lower point (B) of the display (180ma) to the upper point (A) of the display (180ma) with the boundary (BL) as the center. Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0465] Figure 17c (a) illustrates that gradient processing is performed in the direction from the boundary (BL) to the upper point (A) of the display (180ma).

[0466] As shown in (b) of Fig. 17c, when the luminance level of the first display area (Ara) is Lmc1, which is greater than the luminance level of the second display area (Arb), Lma2, the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVba) in which the luminance level increases from the boundary (BL) toward the upper point (A) of the display (180ma). Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0467] As in (c) of Fig. 17c, when the luminance level of the first display area (Ara) is Lmc2, which is lower than the luminance level of the second display area (Arb), Lma2, the signal processing device (170) or the driving control unit (285) can control gradation processing to be performed, such as a curve (CVbb) in which the luminance level decreases from the boundary (BL) toward the upper point (A) of the display (180ma). Accordingly, the visibility of the boundary (BL) area between the first display area (Ara) and the second display area (Arb) can be improved.

[0468] Meanwhile, the signal processing device (170) or the driving control unit (285) can control to perform a pixel shift or a first direction line shift or a second direction line shift when performing the first deterioration compensation mode or the second deterioration compensation mode.

[0469] Meanwhile, the signal processing device (170) or the driving control unit (285) can perform pixel shift or line shift as various examples of deterioration compensation.

[0470] For example, the signal processing device (170) or the driving control unit (285) can control to perform additional pixel shift, additional first direction line shift, or second direction line shift when performing the first deterioration compensation mode or the second deterioration compensation mode. Accordingly, deterioration can be reduced.

[0471] Meanwhile, the display (180ma) of FIGS. 13 to 17c, when operating in pop-up mode or pop-down mode, can operate by dividing three areas within the display (180ma) into a public area and a privacy area, as shown in FIG. 9a.

[0472] For example, when the signal processing device (170) operates in a pop-up mode or a pop-down mode, the signal processing device (170) can control the cluster area, which is the first area (Ar1) of the display (180ma), to operate as a public area, the information display area, which is the second area (Ar2) of the display (180ma), to operate as a public area, and the auxiliary seat area, which is the third area (Ar3) of the display (180ma), to operate as a privacy area. Accordingly, the display can be operated as a switchable privacy display.

[0473] Meanwhile, when the boundary area (Arma) between the second area (Ar2), which is a public area, and the third area (Ar3), which is a privacy area, within the display (180ma) is deteriorated, the signal processing device (170) can control a part (Arma) of the second area (Ar2), which is a public area, to be converted into a privacy area, as shown in (b) of FIG. 12. Accordingly, deterioration of the boundary area can be reduced.

[0474] Meanwhile, when the boundary area (Arna) between the second area (Ar2), which is a public area, and the first area (Ar1), which is a privacy area, within the display (180ma) is deteriorated, the signal processing device (170) can control a part (Arna) of the second area (Ar2), which is a public area, to be converted into a privacy area, as shown in (b) of FIG. 12b. Accordingly, deterioration of the boundary area can be reduced.

[0475] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person skilled in the art to which the present invention pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
