Description

Technical Field

[0001] The present invention relates to a display device, and more particularly, to a display device having a chip on film. Background Art

[0002] The contents described in this Background section simply provide background information about the present invention and may not constitute prior art.

[0003] As we enter the fully mature information age, displays that visually express electrical information signals are rapidly developing. In response to this, various display devices with excellent performance, thin thickness, light weight, and low power consumption are being developed.

[0004] Display devices include liquid crystal display devices (LCD), quantum dot (QD) display devices, field emission display devices (FED), electrowetting display devices (EWD), and organic light emitting display devices (OLED), etc.

[0005] The display device is miniaturized so that the device can be carried by the user. The display device has been developed to be mounted on a movable device such as a vehicle. Therefore, the user can use the display device in the vehicle more conveniently. Summary of the invention

[0006] The display device may include a chip on film (COF). The chip on film may have a driver built into it for driving the display device. The chip on film may be made of a thin flexible material. Therefore, the chip on film is very effective for increasing assembly convenience and reducing the space occupied by the components.

[0007] The chip on film can electrically connect the display panel and the printed circuit board to each other. To this end, the chip on film can be disposed at a position adjacent to the edge of the display panel and can be bent. Therefore, the COF can protrude from the lower end of the display panel.

[0008] The length by which the chip on film protrudes from the lower end of the display panel, that is, its protruding length, refers to the length from the lower end of the display panel to the lower end of the bent portion of the chip on film.

[0009] The protrusion of the chip on film refers to the exposed portion thereof extending from the bottom of the display panel. Therefore, when the user looks at the front of the display panel, the portion corresponding to the protrusion length is visible to the user. This weakens the aesthetics of the display device.

[0010] Therefore, in order to enhance the aesthetics of the display device, a portion corresponding to the protruding length of the chip-on-film is screened by black ink on the cover glass so as not to be visible to the user. This screen portion becomes a frame.

[0011] As the bezel area increases, the aesthetics of the display device may be reduced, and an unnecessary area of ​​the display device may be increased, which may reduce the practicality of the display device. Therefore, in order to reduce the area of ​​the bezel, it is necessary to reduce the protruding length of the chip on film as much as possible.

[0012] In addition, the chip on film may be formed to be thin, and thus may be easily affected by external impact. Therefore, in order to protect the chip on film, it is necessary to minimize the size of a portion of the chip on film exposed to the outside.

[0013] An object of the present invention is to provide a display device having a structure in which the size of a portion of a chip on film provided in the display device that is exposed to the outside is minimized.

[0014] Furthermore, an object of the present invention is to provide a display device having a protective film configured to cover a portion of a chip-on-film exposed to the outside.

[0015] The purpose of the present invention is not limited to the above-mentioned purpose. Other purposes and advantages of the present invention that are not mentioned can be understood based on the following description, and can be more clearly understood based on the embodiments of the present invention. In addition, it will be easy to understand that the purposes and advantages of the present invention can be achieved using the methods shown in the claims and their combinations.

[0016] One embodiment of a display device includes: a display panel for displaying an image; a guide seat disposed at the rear of the display panel; a printed circuit board mounted on the guide seat and electrically connected to the display panel; a chip on film (COF) having one side electrically connected to the display panel and the other side electrically connected to the printed circuit board, wherein a portion of the chip on film is bent to extend across an end of the guide seat; and a protective film attached to one face of the guide seat and constructed to cover the chip on film. The guide seat may be formed at a position corresponding to the position of the end of the protective film, and may include a rib for accommodating a portion of the protective film therein.

[0017] In one embodiment of the display device, the display device may further include: a glass cover; a touch sensor, which is arranged at the rear of the glass cover and at the front of the display panel and recognizes a user's touch input; a polarizer, which is arranged in front of the display panel; a back plate, which is arranged at the rear of the display panel; and a metal plate, which is arranged at the rear of the back plate and at the front of the guide seat, wherein the metal plate has an area larger than that of the guide seat.

[0018] In the display device of the present invention, the rib is formed at the end of the guide base, and the end of the protective film is bent to be accommodated on the inner surface of the rib, thereby preventing the chip on film disposed on the inner surface of the protective film from being exposed to the outside.

[0019] Therefore, the rib allows the protective film to cover the exposed portion of the chip on film and maintain the state where the protective film covers the chip on film, thereby preventing the chip on film from colliding with other portions due to external collision and preventing the chip on film from being damaged due to its contact with foreign materials.

[0020] In addition, in the display device according to the present invention, the rib can stably hold the end of the protective film. Therefore, even if the protective film is slightly deformed due to external impact or other reasons, the protective film can maintain its position without being removed from the rib.

[0021] Therefore, it is possible to effectively suppress the protective film from being removed from the rib portion to expose the chip-on-film provided on the inner face of the protective film to the outside.

[0022] The effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those of ordinary skill in the art from the following description.

[0023] The objects, schemes, and effects of the present invention described above do not specify essential features of the claims. Therefore, the scope of the claims is not limited by the objects, schemes, and effects of the description above. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1 The interior of a vehicle equipped with the display device 10 according to the embodiment is shown.

[0046] The display device 10 according to the embodiment may be installed on a vehicle driving seat, for example, to provide images or videos required by the driver and passengers of the vehicle. However, the present invention is not limited thereto. The display device may not be installed on the vehicle, but may be carried by the user. Hereinafter, the display device 10 installed on the vehicle will be described as an example.

[0047] Figure 2 is a rear view of the display device 10 according to the embodiment. Figure 3 is a side view of the display device 10 according to the embodiment. Figure 4 yes Figure 2 A magnified view of a portion of .

[0048] The display device 10 may have a plurality of displays mounted on one glass cover 610. Therefore, a plurality of display mounting portions 11 may be provided on which not only the display panel 100 described below (see FIG. Figure 7 ) and separate displays are installed respectively. Hereinafter, the display panel 100 disposed in the central area of ​​the glass cover 610 and related components will be mainly described.

[0049] The display device 10 according to the embodiment may include a cover glass 610, a display panel 100, a guide holder 200, a printed circuit board 300, a chip on film 400 (see FIG. Figure 7 ) and a protective film 500.

[0050] The cover glass 610 may be disposed in front of the display device 10. The cover glass 610 may be disposed in front of the display panel 100 to protect the display panel 100. The cover glass 610 is made of a transparent material so that light irradiated to the cover glass 610 may pass through the cover glass 610.

[0051] The display panel 100 may reproduce an image or video. The reproduced image or video may be navigation information required by a driver, an image captured by a camera mounted on a vehicle, or other various contents required by a driver or a passenger.

[0052] The guide base 200 may be disposed at the rear of the display panel 100, and the printed circuit board 300 may be mounted on one surface of the guide base 200. The printed circuit board 300 may be mounted on the guide base 200 and may be electrically connected to the display panel 100.

[0053] The printed circuit board 300 may include devices for communicating with external devices such as a camera and a vehicle main control module, and devices for driving the display panel 100 so that the display panel 100 reproduces an image or video. A circuit may be provided in the printed circuit board, and various active and passive elements may be provided therein.

[0054] One side of the chip on film (COF) 400 may be electrically connected to the display panel 100, and the other side may be electrically connected to the printed circuit board 300. A portion of the COF may be bent to extend across an end of the guide base 200.

[0055] The protective film 500 may be attached to one surface of the guide base 200 and configured to cover the chip on film 400. The protective film 500 may cover the back surface of the printed circuit board 300 connected to the chip on film 400. Therefore, the protective film 500 may prevent the chip on film 400 and the printed circuit board 300 from being exposed to the outside.

[0056] Therefore, the protective film 500 may have an area and a shape that enables the protective film 500 to cover the printed circuit board 300 and the chip-on-film 400 connected thereto.

[0057] The protective film 500 has a thin film form, is made of a bendable flexible material, and can be made of a transparent, translucent or opaque material. For example, the protective film 500 can be made of PET (polyethylene terephthalate) which can be easily processed and has excellent heat resistance. The present invention is not limited thereto.

[0058] The display apparatus 10 may further include a metal plate 650 disposed at the front of the guide base 200 and having an area larger than that of the guide base 200 .

[0059] The metal plate 650 may be disposed at the rear of the display panel 100. The metal plate 650 may be formed to be thin to manufacture a display panel with a slim profile. The metal plate 650 may function as a heat sink for cooling the display panel 100 by radiating heat generated from the display panel 100 to the outside.

[0060] The metal plate 650 may be made of a material that can be easily processed through sheet metal processing, has high heat transfer capability, and has excellent heat resistance, such as aluminum. However, the present invention is not limited thereto.

[0061] The protective film 500 may include an extended attachment portion 510 formed to protrude from an end of the protective film 500 and attached to one surface of the metal plate 650. The extended attachment portion 510 may attach the protective film 500 to the metal plate 650 to prevent the protective film 500 from being easily dropped from the rear of the display device 10.

[0062] Furthermore, the operator may attach the protective film 500 to the rear of the printed circuit board 300 using the extended attaching portion 510 without wrinkling the protective film 500 .

[0063] The display device 10 may further include a main control board 680 and a cable 690. The main control board may be mounted on the guide base 200 and may be electrically connected to the printed circuit board 300. The main control board 680 is electrically connected to a main control module mounted on the vehicle to receive control commands from the main control module. The main control board 680 may share a function with the printed circuit board 300, thereby controlling the operation of the display device 10.

[0064] The second protection panel 681 may be mounted on the rear side of the main control board 680. The second protection panel 681 may be constructed to cover at least a portion of the rear side of the main control board 680 to protect the main control board 680. In one example, the second protection panel 681 may be made of a metal material, thereby being used as a heat sink that transfers heat generated from the main control board 680 to the outside.

[0065] Similar to the printed circuit board 300, the main control board 680 may include a device for driving the display panel 100 so that the display panel 100 reproduces an image or a video. A circuit may be provided in the main control board 680, and various active and passive elements may be provided therein.

[0066] The cable 690 may electrically connect the printed circuit board 300 and the main control board 680 to each other. The cable 690 has a thin shape, is made of a flexible material, and has a plurality of wires built therein.

[0067] The guide seat 200 is formed at a position corresponding to the position of the end of the protective film 500 , and may include a rib 210 for accommodating a portion of the protective film 500 therein.

[0068] The rib 210 is formed at the end of the guide base 200. The end of the protective film is bent to be received on the inner surface of the rib 210, thereby preventing the chip on film 400 disposed on the inner surface of the protective film 500 from being exposed to the outside.

[0069] Therefore, the rib 210 allows the protective film 500 to cover the exposed portion of the film chip 400, and maintains the state in which the protective film 500 covers the film chip 400. This can effectively prevent the film chip 400 from colliding with other parts due to external collision, or can prevent the film chip 400 from being damaged due to its contact with external impurities. The specific structure of the rib 210 will be described below with reference to the accompanying drawings.

[0070] Figure 5 2 is a rear view showing a guide base 200 according to an embodiment. A printed circuit board 300 and a main control board 680 may be mounted on the guide base 200. The guide base 200 may include a first member 201 and a second member 202.

[0071] The printed circuit board 300 may be mounted on the first component 201. The protective film 500 may be provided on the first component 201. The second component 202 may be connected to the first component 201. The main control board 680 may be mounted on the second component. The first component 201 and the second component 202 may be formed integrally with each other.

[0072] The rib 210 configured to surround the end of the protective film 500 may be provided at the end of the first member 201. The rib 210 may include a plurality of ribs. The ribs 210 may be spaced apart from each other.

[0073] Figure 6 yes Figure 5 The rib 210 may be formed to protrude from the end of the guide seat 200, and may be configured to guide the bending of the end of the protective film 500. Therefore, in order to guide the bending of the protective film 500, the rib 210 may have a curved portion.

[0074] Specifically, the rib 210 may include a main body 211 and a bent portion 212. The rib 210 may be formed as one body with the guide seat 200. In addition, the main body 211 and the bent portion 212 may also be formed as one body with each other.

[0075] The body 211 may be constructed to protrude from one end of the guide base 200. The bent portion 212 may be formed to be bent from the body 211. The bent portion 212 may be bent from the body 211 into a curved shape having an appropriate curvature and may protrude toward the rear of the guide base 200.

[0076] When the assembly of the display device 10 is completed, the end of the protective film 500 may be received on the inner surface of the bent portion 212 .

[0077] Figure 7 yes Figure 3 An enlarged view of part A of FIG. Figure 8 yes Figure 4 First, additional components of the display device 10 will be described.

[0078] The display device 10 according to the embodiment may further include a touch sensor 620, a first adhesive layer 660, a polarizer 630, a second adhesive layer 670, and a back plate 640. Each of these components may be formed as a thin film to manufacture a display panel with a slim profile.

[0079] The touch sensor 620 is disposed at the rear of the glass cover 610 and at the front of the display panel 100, and may recognize or sense a user's touch input. The touch sensor 620 may recognize the user's input in a capacitive manner, for example.

[0080] When the user inputs information to the glass cover 610 using a hand or a pen, the touch sensor 620 recognizes the user input. Thus, the user can manipulate the display device 10.

[0081] The first adhesive layer 660 may be disposed between the cover glass 610 and the touch sensor 620. One surface of the first adhesive layer 660 may be adhered to the cover glass 610, and the other surface thereof may be adhered to the touch sensor 620 to adhere the touch sensor 620 to the cover glass 610.

[0082] The polarizer 630 may be disposed in front of the display panel 100. The polarizer 630 may be disposed in front of the display panel 100 to polarize light emitted from the display panel 100, thereby providing a clear image or video to the user.

[0083] The second adhesive layer 670 may be disposed between the touch sensor 620 and the polarizer 630. One surface of the second adhesive layer 670 is adhered to the touch sensor 620, and the other surface thereof is adhered to the polarizer 630, so that the polarizer 630 may be adhered to the display panel 100.

[0084] The back plate 640 may be disposed at the rear of the display panel 100. The metal plate 650 may be disposed at the rear of the back plate 640. The back plate 640 may be attached to the rear of the display panel 100 to prevent the display panel 100 from being bent and damaged. That is, the back plate 640 may be used to strengthen the rigidity of the display panel 100.

[0085] The back plate 640 may be in the form of a film, and may be attached to the display panel 100. However, the present invention is not limited thereto.

[0086] The printed circuit board 300 may be mounted on the rear of the guide base 200. The display panel 100 may be disposed in the front of the guide base 200. Therefore, in order to electrically connect the chip on film 400 to the printed circuit board 300 and the display panel 100, opposite ends of the chip on film 400 must be bonded to the printed circuit board 300 and the display panel 100, respectively.

[0087] Therefore, the chip on film 400 may extend beyond the metal plate 650 between the guide base 200 and the display panel 100 , and further, may extend across the end of the guide base 200 .

[0088] Thus, when the display device 10 has been assembled, the chip on film 400 may be constructed to extend beyond the metal plate 650 and the guide base 200 , and to extend across the lower end of the guide base 200 .

[0089] Therefore, a portion of the chip on film 400 extending beyond the metal plate 650 and the guide seat 200 and corresponding to the lower end of the metal plate 650 may be bent. In addition, due to this structure, the chip on film 400 may be constructed to protrude from the lower end of the metal plate 650.

[0090] The chip on film 400 and the rib 210 may be disposed at positions corresponding to each other. Therefore, the chip on film 400 may be constructed to extend through the body 211 of the rib 210 and along the inner surface of the bent portion 212 of the rib 210 .

[0091] Due to this structure, a portion of the exposed portion of the chip on film 400 exposed to the outside may be surrounded by the rib 210 .

[0092] The bent portion 212 of the rib 210 may be bent to cover at least a portion of the bent portion of the chip on film 400 .

[0093] When the display device 10 is assembled, Figure 7 and Figure 8 As shown, a portion of the chip on film 400 located at the rear of the guide seat 200 may be covered by the protective film 500 and thus not exposed to the outside. This is because the end of the protective film 500 is disposed on the entire inner surface of the curved portion 212 of the rib 210.

[0094] That is, the end portion of the protection film 500 guided and bent along the bent portion 212 is disposed on the inner surface of the bent portion 212 .

[0095] The protection film 500 and the chip-on-film 400 may overlap each other in a region corresponding to the bent portion 212 , so that the chip-on-film 400 may be prevented from being exposed to the outside by the protection film 500 .

[0096] In addition, the protective film 500 may be constructed to include a portion corresponding to the bent portion 212 and located at the rear of the guide seat 200. Thus, the protective film 500 may cover the entire chip-on-film 400. Therefore, a portion of the chip-on-film 400 disposed at the rear of the guide seat 200 may be covered by the protective film 500, thereby preventing the COF 400 from being exposed to the outside.

[0097] A portion of the protective film 500 may be bent so that it may contact at least a portion of the inner surface of the curved portion 212 of the rib 210. The curved portion 212 may be spaced apart from the rear of the guide seat 200. When the protective film 500 is inserted into the space between the curved portion 212 of the rib 210 and the rear of the guide seat 200, the protective film 500 may be bent along the curved portion 212 and may come into contact with at least a portion of the inner surface of the curved portion 212. In this regard, an end portion of the protective film 500 may be disposed at a point where the body 211 of the rib 210 and the curved portion 212 meet each other.

[0098] Due to the above structure, the protective film 500 can completely cover the film chip 400 disposed at the rear of the guide seat 200. Therefore, the film chip 400 can be suppressed from being exposed to the outside as much as possible. Thus, the film chip 400 can be prevented from colliding with other parts due to external collision, or the film chip 400 can be prevented from being damaged due to its contact with external impurities.

[0099] In addition, the rib 210 stably holds the end of the protective film 500. Thus, even if the protective film 500 is slightly deformed due to external impact or other reasons, the protective film 500 can maintain its position without being removed from the rib 210.

[0100] Therefore, it is possible to effectively suppress the protective film 500 from being removed from the rib 210 and thus exposing the chip-on-film 400 to the outside.

[0101] Fig. 9 is a partial view in which the protective film 500 is omitted from the display apparatus 10 according to the embodiment.

[0102] The first protective panel 310 may be mounted on the rear side of the printed circuit board 300. The first protective panel 310 may be configured to cover at least a portion of the rear side of the printed circuit board 300 to protect the printed circuit board 300. In one example, the first protective panel 310 may be made of a metal material, and may function as a heat sink that transfers heat generated from the printed circuit board 300 to the outside.

[0103] like Fig. 9 As shown, the rib 210 may include a plurality of ribs. The ribs 210 may be constructed to be spaced apart from each other by a predetermined distance and may be provided at an end of the guide base 200.

[0104] When the number of the ribs 210 is large, the ribs 210 may more stably hold the protection film 500 , thereby effectively preventing the protection film 500 from being removed from the ribs 210 and thus exposing the chip-on-film 400 to the outside.

[0105] However, when the number of the ribs 210 is too large, it may be difficult to mount the protective film 500 on the ribs 210. While taking these advantages and disadvantages into consideration, the number of the ribs 210 may be appropriately selected.

[0106] The chip on film (COF) 400 may include a plurality of COFs. In this regard, each chip on film 400 may be disposed at a position other than the positions of the plurality of ribs 210. That is, each chip on film 400 may be disposed at a position that does not correspond to the position of each rib 210. In order to connect the opposite ends of the chip on film 400 to the printed circuit board 300 and the display panel 100, respectively, the positions of the chip on film 400 and the ribs 210 are separated from each other in the lateral direction of the display device 10.

[0107] For example, Fig. 9 As shown, the chip on film 400 and the ribs 210 may be arranged alternately with each other in the lateral direction of the guide seat 200. However, the present invention is not limited thereto.

[0108] Fig.10 is a partial view showing a process of mounting the protective film 500 on the display device 10 according to the embodiment. Fig.11 It is shown Fig.10 The protective film 500 is now installed.

[0109] The process of mounting the protective film 500 on the display device 10 may be performed in the following order. Fig.10 As shown, the operator may insert the end of the protective film 500 into a gap formed by the rear surface of the guide base 200 and the bent portion 212 of the rib 210 which are spaced apart from each other.

[0110] After the end of the protective film 500 is inserted into the gap, the protective film 500 is pushed toward the rib 210. Thus, the end of the protective film 500 is guided and bent by the bent portion 212, and then moves forward toward the body 211 of the rib 210.

[0111] When the tip of the protective film 500 contacts the point where the body 211 and the bent portion 212 of the rib 210 meet each other, the protective film 500 no longer moves forward. In this state, when the operator attaches the protective film 500 to the rear of the printed circuit board 300 and the rear of the metal plate 650, the installation of the protective film 500 can be completed. Fig.11 The protective film 500 is shown in a state where installation is completed.
