[0033] Reference Figure 2 The control unit C of the display device 1 can control the operation of the display device 1. The control unit C can be electrically connected to the components of the display device 1.

[0034] The display panel 11, the main board 11m, the power supply board 11p and the timing controller board 11c may be provided on the cover 90 (see Figure 1) and is electrically connected to the control unit C.

[0037] The communication unit Cm can transmit information from the display device 1 to an external device, or transmit various information or signals from an external device to the display device 1. The communication unit Cm can communicate with a remote control device, a portable terminal, a wired / wireless router, or other communication facilities (e.g., a server).

[0038] The memory 11r can be electrically connected to the control unit C. The memory 11r can store basic data of the display device 1 (e.g., basic configuration information for each component of the display device, such as display resolution, brightness, and sound output values), data and programs for controlling the operation of the display device 1, data input from the outside, or data processed by the control unit C. For example, the memory 11r can store information regarding the operation of the motor 31. For example, the memory 11r can include ROM, RAM, EPROM, a flash drive, or a hard disk drive.

[0039] On the other hand, the control unit C may be electrically connected to a first sensor 70 , a second sensor 80 , and a counter sensor 90 to be described later.

[0040] Reference Figure 3The display 10 may include a display panel 11, a first interface unit 11a, a second interface unit 11b, a timing controller 11c, a gate driver 11d, a data driver 11e, a memory 11f, a processor 11g, a power supply unit 11h, and a current detection unit 11i. The display panel 11 may be an OLED (Organic Light Emitting Diode) panel.

[0041] The first interface portion 11 a may receive a first DC power source V1 from a power supply portion outside the display 10 , and the first DC power source V1 may be used for the operation of the power supply portion 11 h and the timing controller 11 c .

[0042] The second interface portion 11 b may receive a second DC power source V2 from a power supply portion outside the display 10 , and the second DC power source V2 may be provided to the data driving portion 11 e .

[0043] The timing controller 11c can output a data drive signal Sda and a gate drive signal Sga based on the image signal Vd input to the first interface unit 11a. For example, the first interface unit 11a can convert the image signal Vd to output the converted image signal Va1, and the timing controller 11c can output the data drive signal Sda and the gate drive signal Sga based on the converted image signal Va1. This data drive signal Sda can be a driving signal for the subpixels of the display panel 11. In addition, the timing controller 11c can also output a control signal Cs to the data drive unit 11e.

[0044] The gate driving unit 11d and the data driving unit 11e can provide scanning signals and image signals to the display panel 11 through the gate lines GL and the data lines DL according to the gate driving signals Sga and the data driving signals Sda of the timing controller 11c, so that the display panel 11 can display images.

[0045] The power supply unit 11 h can provide various power sources to the gate driving unit 11 d , the data driving unit 11 e , the timing controller 11 c , and the like.

[0046] The current detection unit 11i can detect the current flowing through the sub-pixels of the display panel 11. The detected current can be input to the processor 11g for current accumulation calculation. The calculated accumulated current can be stored in the memory 11f.

[0047] The processor 11g can perform various controls within the display 10. For example, the processor 11g can control the gate driving unit 11d, the data driving unit 11e, and the timing controller 11c.

[0048] Reference Figure 4 and Figure 5, the display panel 11 may include 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. The plurality of data lines R1, G1, B1, W1 to Rm, Gm, Bm, Wm may intersect with the plurality of scan lines Scan 1 to Scan n. Subpixels may be defined at the intersection of the scan lines and the data lines. A pixel may be a holding element that continuously emits light in the organic light-emitting layer OLED during a unit frame image after a scan signal is applied. For example, a pixel may have RGBW subpixels. As another example, a pixel may have RGB subpixels.

[0049] The circuit CRTm of the subpixel is an active type and may include a scan switching element SW1 , a storage capacitor Cst, a drive switching element SW2 , and an organic light emitting layer OLED.

[0050] The scan switch element SW1 can be turned on according to the scan signal Vscan input from the scan line. If the scan switch element SW1 is turned on, the scan switch element SW1 can transfer the data signal Vdata input from the data line to one end of the storage capacitor Cst or the gate terminal of the drive switch element SW2.

[0051] The storage capacitor Cst may be provided between the gate terminal and the source terminal of the driving switching element SW2 and store a difference between a data signal level transferred to one end of the storage capacitor Cst and a level of a DC power source VDD transferred to the other end of the storage capacitor Cst.

[0052] For example, if the data signals have different levels using a PAM (Pulse Amplitude Modulation) method, the power level stored in the storage capacitor Cst can vary depending on the level difference of the data signal Vdata. As another example, if the data signals have different pulse widths using a PWM (Pulse Width Modulation) method, the power level stored in the storage capacitor Cst can vary depending on the pulse width difference of the data signal Vdata.

[0053] The driving switch element SW2 can be turned on according to the power level stored in the storage capacitor Cst. If the driving switch element SW2 is turned on, a driving current IOLED proportional to the stored power level can flow through the organic light-emitting layer OLED. As a result, the organic light-emitting layer OLED can emit light.

[0054] The organic light-emitting layer OLED may have an RGBW light-emitting layer (EML) corresponding to the sub-pixel, 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). In addition, it may also include a hole blocking layer (HBL) and the like.

[0055] on the other hand, Figure 5 In FIG. 1 , p-type MOSFETs are shown as the scan switch element SW1 and the drive switch element SW2 , but n-type MOSFETs, JFETs, IGBTs, SICs, and other switching elements may also be used.

[0056] Reference Figure 6 A pixel may include a light emitting region and a transparent region. In the light emitting region, RGBW (Red, Green, Blue, White) subpixels may be arranged vertically, while the transparent region without subpixels may be arranged next to the light emitting region.

[0057] Thus, the display panel 11 having a plurality of pixels can not only display images but also transmit light. The display panel 11 can be called a transparent display panel or a transparent OLED panel.

[0058] Reference Figure 7 A pixel may include a light emitting region and a transparent region. In the light emitting region, RGW (Red, Green, White) or BGW (Blue, Green, White) subpixels may be arranged adjacent to each other, while the transparent region without subpixels may be arranged next to the light emitting region.

[0059] Thus, the display panel 11 having a plurality of pixels can not only display images but also transmit light. The display panel 11 can be referred to as a transparent display panel or a transparent OLED panel.

[0060] Reference Figure 8The display panel 11 can divide an image into a plurality of pixels and output an image after matching the color, brightness, and saturation of each pixel. The display panel 11 can be divided into an active area (active area) for displaying an image and a deactive area (de-active area) for not displaying an image. The display panel 11 can generate light corresponding to red (R), green (G), or blue (B) according to a control signal.

[0061] The source PCB 14 can be adjacent to the bottom edge of the display panel 11. The source PCB 14 can extend along the bottom edge of the display panel 11. The source PCB 14 can be electrically connected to the display panel 11 using a chip on film 15.

The adhesive film 12 may be an optically clear adhesive film (OCA). The transparent panel 13 may be referred to as the front panel 13.

[0063] In addition, the adhesive film 12 may cover at least a portion of the back surface of the transparent panel 13. For example, one side of the adhesive film 12 may be located closer to the center of the display panel 11 than the corresponding side of the transparent panel 13. For example, the top, left, and right sides of the adhesive film 12 may be adjacent to the top, left, and right sides of the transparent panel 13, respectively, while the bottom side of the adhesive film 12 may be spaced upward from the bottom side of the transparent panel 13.

[0064] Furthermore, the size of the adhesive film 12 may correspond to the size of the display panel 11. For example, the diagonal length Db of the adhesive film 12 may be substantially the same as the diagonal length Da of the display panel 11. As another example, the diagonal length Db of the adhesive film 12 may be greater than the diagonal length Da of the display panel 11. In this case, a portion of the adhesive film 12 may be disposed outside the display panel 11 along the periphery of the display panel 11.

The second wire 40b bent due to the second upper pulley 42b can be located on the right side of the second guide frame 49, can extend in a direction parallel to the second guide frame 49, and can be fixed to the portion 52b of the bar 52 adjacent to the left end.

[0129] The second protrusion 522 defines the left end of the bar 52 and can be vertically inserted into the second guide groove 49g of the second guide frame 49. The second guide groove 49g can be formed on the right side of the second guide frame 49 and extend in the vertical direction.

[0130] The second guide frame 49 may be coupled to the rear side of the second frame 24b. The second guide frame 49 may include a second front guide frame 491 and a second rear guide frame 492. The second front guide frame 491 may face the rear side of the second frame 24b. The second rear guide frame 492 may be located behind the second front guide frame 491 and face the second front guide frame 491. A second guide groove 49g may be formed between the second front guide frame 491 and the second rear guide frame 492. The second front guide frame 491 may include a third horizontal portion 491a. The third horizontal portion 491a may be parallel to the second frame 24b. For example, the third horizontal portion 491a may be in the shape of a plate extending vertically. The second front guide frame 491 may include a third vertical portion 491b. The third vertical portion 491b may extend rearward from one side of the third horizontal portion 491a. The third vertical portion 491b may face the second side frame 22. The third horizontal portion 491a and the third vertical portion 491b may be integrally formed.

[0131] The second rear guide frame 492 may include a fourth horizontal portion 492a. The fourth horizontal portion 492a may face the third horizontal portion 491a. The fourth horizontal portion 492a may be parallel to the third horizontal portion 491a. For example, the fourth horizontal portion 492a may be in the shape of a plate extending in a vertical direction. The fourth horizontal portion 492a may be spaced rearward from the third horizontal portion 491a. The second guide groove 49g may be formed between the third horizontal portion 491a and the fourth horizontal portion 492a. The second rear guide frame 492 may include a fourth vertical portion 492b. The fourth vertical portion 492b may extend forward from one side of the fourth horizontal portion 491a. The fourth vertical portion 492b may face the third vertical portion 491b.

[0132] The upper end of the second front guide frame 491 may be flush with the upper end of the second rear guide frame 492. The lower end of the second front guide frame 491 may be flush with the lower end of the second rear guide frame 492. That is, the vertical length of the second front guide frame 491 may be the same as the vertical length of the second rear guide frame 492.

[0133] The second wire 40b may be fixed to the left end 52b of the strip 52. A hole 52ba for inserting and fixing the second wire 40b may be formed at the left end 52b of the strip 52. The hole 52ba may be formed through the top and bottom surfaces of the left end 52b.

[0134] The second guide protrusion 522 may protrude leftward from the left end 52b. A second cap 524 may be mounted on the second guide protrusion 522. The second cap 524 may cover the second guide protrusion 522. The second guide protrusion 522 may be formed of a metal material, and the second cap 524 may be formed of a plastic material. The second cap 524 may be formed of a conductive plastic material. For example, the second cap 524 may be formed of POM (Polyoxymethylene).

[0135] The second guide protrusion 522 with the second cap 524 can be located between the second guide grooves 49g of the second guide frame 49 and can move within the second guide grooves 49g as the bar 52 moves. The second cap 524 can minimize the friction between the metal second guide frame 49 and the metal bar 52.

[0136] Reference Figure 21 and Figure 25The second wire 40b can extend from the second reel 40Q and bend around either the third tensioning pulley 412b or the fourth tensioning pulley 413b, thereby allowing it to bend. For example, the second wire 40b can bend around the circumference of the third tensioning pulley 412b, then bend around the circumference of the second guide pulley 411b. For example, the second wire 40b can bend around the circumference of the fourth tensioning pulley 413b, then bend around the circumference of the second guide pulley 411b. For example, the second wire 40b can bend around both the third tensioning pulley 412b and the fourth tensioning pulley 413b, then bend around the circumference of the second guide pulley 411b. In this case, the second wire 40b can first bend around the third tensioning pulley 412b, then around the fourth tensioning pulley 413b, and finally around the circumference of the second guide pulley 411b. In this case, the second wire 40b can bend in a zigzag shape. Thereby, the tension of the first wire 40a can be adjusted.

[0137] Reference Figure 26 The coupler 53 can move toward the direction close to the third frame 24c to rise, or move toward the direction away from the third frame 24c to fall. The motor 31 can rotate the first gear 34 in the first rotation direction RD1 or the second rotation direction RD2 opposite to the first rotation direction RD1 (refer to Figure 20 The motor 31 can rotate the fourth gear 37 in the first rotation direction RD1 or the second rotation direction RD2 opposite to the first rotation direction RD1 (see Figure 21 At this time, the first gear 34 and the fourth gear 37 can be rotated in the same direction by the motor 31. The first gear 34 and the fourth gear 37 can be rotated simultaneously by the motor 31.

[0138] If the first gear 34 and the fourth gear 37 rotate in the first rotation direction RD1 in response to the action of the motor 31, the first reel 40P and the second reel 40Q can rotate in the first rotation direction RD1. Furthermore, if the first gear 34 and the fourth gear 37 rotate in the first rotation direction RD1 in response to the action of the motor 31, the second gear 35 and the third gear 36 can rotate in the second rotation direction RD2. At this time, the roller 50 can rotate in the second rotation direction RD2 via the second gear 35 and the third gear 36. Furthermore, the first wire 40a and the second wire 40b can be wound around the first groove 40Pg and the second groove 40Qg, respectively, and the first wire 40a and the second wire 40b can pull the bar 52 upward. In response to the rise of the bar 53 and the rotation of the roller 50, the cover sheet 51 can be unwound from the roller 50 and gradually cover the rear of the display panel 11. This action of the drive assembly 30 can be referred to as an unfolding action or a light-shielding action.

[0139] If the first gear 34 and the fourth gear 37 rotate in the second rotation direction RD2 corresponding to the action of the motor 31, the first reel 40P and the second reel 40Q can rotate in the second rotation direction RD2. In addition, if the first gear 34 and the fourth gear 37 rotate in the second rotation direction RD2 corresponding to the action of the motor 31, the second gear 35 and the third gear 36 can rotate in the first rotation direction RD1. At this time, the roller 50 can rotate in the first rotation direction RD1. In addition, the first wire 40a and the second wire 40b can be unwound from the first groove 40Pg and the second groove 40Qg, respectively, and the bar 52 can descend to the lower side. Corresponding to the descent of the bar 52 and the rotation of the roller 50, the cover sheet 51 can be wound around the roller 50, and the rear of the display panel 11 can be gradually opened. This action of the drive assembly 30 can be referred to as a winding action or an opening action.

[0140] Reference Figure 27 In response to the aforementioned light shielding operation, the cover sheet 51 unwound from the roller 50 can cover the rear of the display 10. At this time, the wires 40a and 40b can be wound around the grooves 40Pg and 40Qg a plurality of times. Figure 27 4 is a cross-sectional view showing a cross section of the driving assembly 30 when the first wire 40a is wound a plurality of times in the first groove 40Pg by the light shielding operation.

[0141] The first reel 40P may include a first groove 40Pg formed between the first disk 40P1 and the second disk 40P2. The first groove 40Pg may have a depth Rg in the vertical direction. The depth Rg of the first groove 40Pg may be formed to a depth that allows the first wire 40a to be wound a plurality of times. For example, the first wire 40a having a predetermined diameter Dw may be wound seven times. For example, the diameter Dw of the first wire 40g may be 0.6 mm.

[0142] The width Wg of the first groove 40Pg can be greater than the diameter Dw of the first wire 40g and less than twice the diameter Dw. In this case, the first wire 40a can be configured in a zigzag shape and wound a plurality of turns in the first groove 40Pg. For example, the height h1 of the first wire 40aN1 that is first wound in the first groove 40Pg can have the same value as the diameter Dw of the first wire 40a, but the height h2 of the second wound first wire 40aN2 can have a value smaller than twice the diameter Dw of the first wire 40a. Since the width Wg of the first groove 40Pg is greater than the diameter Dw of the first wire 40g and less than twice the diameter Dw, it is possible to prevent the wound first wire 40g from moving in the first groove 40Pg.

[0143] The aforementioned contents regarding the first wire 40a and the first groove 40Pg can be similarly applied to the second wire 40b and the second groove 40Qg. That is, the diameter Dw of the first wire 40a can be substantially the same as the diameter of the second wire 40b, and the width Wg and depth Rg of the first groove 40Pg can be substantially the same as the width and depth of the second groove 40Qg. The second wire 40b can be configured in a zigzag shape and wound a plurality of times around the second groove 40Qg.

[0144] Thus, the extent to which the second wire 40b is wound in the second groove 40Qg and the extent to which the first wire 40a is wound in the first groove 40Pg can be synchronized, thereby minimizing the height difference between the left upper end and the right upper end of the cover sheet 51 .

[0153] The structure of the sensors 70 and 80 allows them to be installed even in a narrow space. For example, the sensors 70 and 80 can be installed in a thin frame supporting the display panel 11. This allows the sensors 70 and 80 to perform accurate detection.

[0154] Reference Figures 29 to 31 The cover frames 18a, 18b, 18c, and 18d may be arranged along the display panel 11 (see Figure 8 ) extending from the periphery of the cover frame.

For example, support ribs 18s can be formed on the third cover frame 18c.

[0159] Reference Figure 12 When at least one of the rear cover 19 and the cover frames 18a, 18b, or 18c is coupled to the frame 24, the alignment ribs 18r can be inserted into the alignment grooves 24h. The pair of alignment ribs 18r can be inserted into the pair of alignment grooves 24h. The hooks 18H can be inserted into or fastened to the engaging portions 24L. This allows alignment between the hooks 18H and the engaging portions 24L.

[0160] Reference Figure 14If at least one of the rear cover 19 and the cover frames 18a, 18b, or 18c is coupled to the frame 24, the support ribs 18s can be positioned on the inner wall 24I of the third frame 24c. The support ribs 18s can be supported by the inner wall 24I of the third frame 24c. This prevents sagging of at least one of the rear cover 19 and the cover frame 18.

[0161] Reference Figure 32 The display panel 11 may be fixed to the back of the transparent panel 13 via the adhesive film 12. The fixing member 16 may extend long along the side of the display panel 11 and be fixed to the back of the transparent panel 13. The frame 24 may be coupled to or fixed to the fixing member 16.

[0164] Reference Figure 34 In the figure on the upper side of the display 10, the cover sheet 51 does not need to cover the rear of the display 10. For example, the display 10 may not output an image, and a user in front of the display 10 can see the rear of the display 10 (see the man Mh wearing a hat indicated by the dotted line). As another example, the display 10 may output an image, and a user in front of the display 10 can see the image (see the fish Fs indicated by the solid line) and the rear of the display 10 (see the man Mh wearing a hat indicated by the dotted line). This mode is referred to as a light-transmitting mode.

[0165] Reference Figure 34 As shown in the figure below, the cover sheet 51 can cover the rear of the display 10. The display 10 can output an image or not output an image, and the user in front of the display 10 cannot see the rear of the display 10. This mode can be called a light shielding mode.

[0166] In the light shielding mode, the visibility of the image output from the display 10 may be stronger than that in the light transmitting mode (refer to FIG. Figure 34 The fish Fs is represented by a thin line and the fish F is represented by a thick line).

[0167] Reference Figure 35 As shown in the upper drawing of FIG, the cover sheet 51 may not cover the rear of the display 10. This mode may be referred to as a completely light-transmitting mode.

[0168] Reference Figure 35 , the cover sheet 51 may cover a portion of the rear of the display 10. This mode may be referred to as a partial light-shielding mode or a partial light-transmitting mode.
