1. Field of the Invention
The present invention relates to a connector assembly and a display apparatus having the same. More particularly, the present invention relates to a connector assembly having a thin structure providing improved production efficiency and image display quality, and a display apparatus having the connector assembly
2. Description of the Related Art
A liquid crystal display (“LCD”) has a thin structure, light weight and operates at lower power consumption than other types of displays, such as a cathode ray tube (“CRT”), for example. As a result, the LCD is used extensively in various industrial fields. The LCD typically includes a liquid crystal display panel to display images thereon, a backlight unit which provides light to the liquid crystal display panel and a driving circuit which provides driving signals to the liquid crystal display panel.
The driving circuit generally includes a gate driver to drive gate lines of the liquid crystal display panel, a data driver to drive data lines of the liquid crystal display panel and a printed circuit board which supplies control signals and/or power to the gate driver and the data driver. A connector, which receives external power and control signals, is mounted on the printed circuit board. More specifically, the connector is typically connected to a signal transmission film on the printed circuit board to electrically connect the printed circuit board to the signal transmission film in order to provide the external power and control signals to the driving circuit.
As a thickness of the LCD is reduced, however, a thickness of the connector must also be reduced. As a result, a connector having the reduced thickness is easily damaged when the LCD is manufactured, and a productivity of manufacturing the LCD is thereby reduced. In addition, a connection fault often occurs, due to the reduced thickness of the connector, and a display quality of the image displayed on the LCD therefore deteriorates.
An exemplary embodiment of the present invention provides a connector assembly having a thin structure which is easily manufactured without being damaged.
An alternative exemplary embodiment of the present invention provides a display apparatus including the connector assembly having the thin structure.
In an exemplary embodiment of the present invention, a connector assembly includes a first connector, a second connector and a lever. The first connector has a recess disposed in a first side thereof. The second connector is disposed in the recess and is connected to the first connector. The lever is rotatably connected to the second connector. The lever is rotated toward the first connector by an external force after the second connector is connected to the first connector, and is connected to the first connector to fix the second connector in the recess of the first connector.
The first connector may include a lever fixing member which receives the lever to fix the lever to the first connector.
The lever fixing member may include a protrusion which protrudes outward from the lever fixing member from at least one of a second side opposite to the first side having the recess disposed therein and a third side adjacent to the first side having the recess.
The lever may include a first rotating member rotatably connected to a first side of the second connector, a second rotating member rotatably connected to a second side of the second connector, the second side of the second connector disposed opposite to the first side of the second connector, and a connection bar connecting the first rotating member to the second rotating member.
The lever fixing member may be disposed on the second surface opposite to the first surface having the recess, and the connection bar may be fixed to the lever fixing member.
The first connector may include a first terminal and the second connector may include a second terminal.
The connector assembly may further include an auxiliary handle connected to the lever, and the auxiliary handle may include an insulating material.
In an alternative exemplary embodiment of the present invention, a display apparatus includes a display panel, a backlight assembly, a gate driver, a data driver, a timing controller, a driving circuit board, a first connector, a second connector, a signal transmission member and a lever.
The display panel includes a gate line and a data line disposed thereon. The backlight assembly supplies light to the display panel. The gate driver drives the gate line and the data driver drives the data line. The timing controller supplies a control signal to the gate driver and the data driver. The timing controller is disposed on the driving circuit board. The first connector is disposed on the driving circuit board. The first connector is electrically connected to the driving circuit board and a recess is disposed in a first side thereof The second connector is disposed in the recess and is connected to the first connector. The signal transmission member is connected to the second connector to supply an external power signal and/or an external driving signal to the driving circuit board. The lever is rotatably connected to the second connector. The lever is rotated toward the first connector by an external force after the second connector is connected to the first connector, and is connected to the first connector to fix the second connector in the recess of the first connector.
The first connector may include a lever fixing member which receives the lever to fix the lever to the first connector.
The lever fixing member may include a protrusion which protrudes from the lever fixing member from at least one of a second side opposite to the first side having the recess disposed therein and a third side adjacent to the first side having the recess.
The lever may include: a first rotating member rotatably connected to first side of the second connector; a second rotating member rotatably connected to a second side of the second connector, the second side of the second connector disposed opposite to the first side of the second connector; and a connection bar connecting the first rotating member to the second rotating member.
The protrusion may be disposed on the third side opposite to the first side having the recess, and the connection bar may be fixed to the protrusion.
The first connector may include a first terminal, and the second connector may include a second terminal.
In yet another alternative exemplary embodiment of the present invention a method of connecting a connector assembly, the connector assembly including a first connector having a recess disposed therein, includes: disposing a second connector in the recess, the second connector including a lever attached thereto; applying an external force to the lever; and rotating the lever toward the first connector to fix the second connector in the recess of the first connector.
The method may further include receiving the lever in a lever fixing member of the first connector.
Thus, according to exemplary embodiments of the present invention, a lever is connected to a second connector and a first connector is connected to the second connector through the lever. Thus, the lever connected to the first connector fixes the first connector to the second connector. As a result, the first connector is easily connected to the second connector, effectively preventing the second connector from being separated from the first connector. Therefore, a driving circuit board is easily connected to a signal transmission member, thereby substantially decreasing an assembling time of a display apparatus while also preventing connection faults from forming while assembling the display apparatus, thereby effectively improving a display quality of an image displayed thereon.
The above and other aspects, features and advantages of the present invention will become more readily apparent by describing in further detail exemplary embodiments thereof with reference to the accompanying drawings, in which:
The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals refer to like elements throughout.
It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including,” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components and/or groups thereof.
Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top” may be used herein to describe one element's relationship to other elements as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on the “upper” side of the other elements. The exemplary term “lower” can, therefore, encompass both an orientation of “lower” and “upper,” depending upon the particular orientation of the figure. Similarly, if the device in one of the figures were turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning which is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Exemplary embodiments of the present invention are described herein with reference to cross section illustrations which are schematic illustrations of idealized embodiments of the present invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the present invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes which result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles which are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present invention.
Hereinafter, exemplary embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

The first connector 260 according to an exemplary embodiment includes a first housing 261, a recess 263, a first terminal 265 and a lever fixing member 267.
The first housing 261 is coupled with, e.g., is connected to, the driving circuit board 240. In an exemplary embodiment of the present invention, the first housing 261 is an insulating member having a substantially rectangular shape. In an exemplary embodiment, for example, the first housing 261 is made from plastic and is bonded to the driving circuit board 240 with an adhesive, but alternative exemplary embodiments of the present invention are not limited thereto.
The recess 263 is disposed in a first side of the first housing 261, as shown in
The first terminal 265 according to an exemplary embodiment includes a plurality of leads disposed at a second side of the first housing 261 opposite the recess 263, e.g., opposite to the first side thereof At least a portion of the first terminal 265 is disposed in the first housing 261. Thus, the first terminal 265 is at least partially exposed through the recess 263 at the first side of the first housing 261. In addition, the first terminal 265 is electrically connected to a plurality of signal transmission lines 245 disposed on the driving circuit board 240.
In an exemplary embodiment, the lever fixing member 267 is disposed on a third side of the first housing 261, e.g., adjacent to the recess 263 on the first side of the first housing 261, but alternative exemplary embodiments of the present invention are not limited thereto. For example, the lever fixing member 267 may be disposed on the second side, e.g., opposite to the recess 263. The lever fixing member 267 protrudes from the first housing 261 to fix the lever 275 thereto, as best shown in
In an exemplary embodiment, the second connector 270 includes a second terminal 271 and a second housing 273. In addition, the second connector 270 is connected to the signal transmission member 280 which transmits the external power and/or the external driving signals.
In an exemplary embodiment, the second terminal 271 includes a plurality of conductive pins. The second terminal 271 is fitted into the recess 263 and is thereby electrically connected to the first terminal 265. In an exemplary embodiment of the present invention, the second terminal 271 may include an insulating substrate having a plurality of signal lines disposed thereon, for example.
The second housing 273 is coupled with, e.g., is connected to, the second terminal 271. In addition, the second housing 273 covers at least a portion of the second terminal 271. Thus, the second housing 273 includes an insulating member which covers a portion of the second terminal 271. In an exemplary embodiment, the second housing 273 is integrally formed with, e.g., is a part of, the second terminal 271.
The lever 275 is connected to, e.g., is coupled to, a first side and an opposite second side of the second housing 273, as shown in
The first and second rotating members 277 are inserted into holes, e.g., apertures, disposed at the first and second sides, respectively, of the second housing 273 adjacent to the first terminal 265. Further, first end portions of each of the first and second rotating members 277, are bent to be inserted into the holes in the second housing 273. Thus, the first and second rotating members 277 rotate about an axis defined by the end portions thereof inserted into the holes. The connection bar 278 connects opposite second ends of the first and second rotating members 277, which are coupled to both sides of the second housing 273, to each other. Thus, the connection bar 278 is connected between the second end portions of the first and second rotating members 277 to serve as a handle, for example.
In an exemplary embodiment, the lever 275 may be formed by connecting the rotating members 277 to the connection bar 278. In addition, the lever 275 may be formed by bending a rod, for example, such that the rod is divided to integrally form the first and second rotating members 278 and the connection bar 278.
In an exemplary embodiment of the present invention, the lever 275 includes an insulating material or, alternatively, a conductive material. When the lever 275 is made from the conductive material, an auxiliary handle 290 is connected to the lever 275 to electrically insulate the lever 275, as shown in
The auxiliary handle 290 is connected to the connection bar 278. Further, the auxiliary handle 290 is made from an insulating material. For example, the auxiliary handle 290 according to an exemplary embodiment is made from an insulating film which is connected to the connection bar 278. In an exemplary embodiment of the present invention, the auxiliary handle 290 may be connected to the lever 275 even when the lever 275 includes the insulating material, since the auxiliary handle 290 allows a user to easily move the lever 275.
The second connector 270 is electrically connected to the first connector 260. Specifically, the second connector 270 moves toward the first connector 260 such that the second connector 270 is coupled with, e.g., is connected to, the first connector 260 mounted on the driving circuit board 240. When the second connector 270 is connected to the first connector 260, the power and driving signals, which are input from the signal transmission member 280, are transferred to the first connector 260.
After the first connector 260 has been connected to the second connector 270, the lever 275 is rotated toward the first connector 260. As a result, the lever 275 is coupled with, e.g., is connected or fixed to, the first connector 260. Thus, the lever 275 effectively prevents the second connector 270 from being separated from the first connector 260.
The lever 275 is connected to the first connector 260 and is thereby fixed by the lever fixing member 267.
