In such a mobile display device, a window glass is provided to protect the liquid crystal display device by blocking it from the outside. That is, a bottom cover set for protecting the liquid crystal display device is provided, and the bottom cover set is provided with an inner groove for embedding a liquid crystal display device, more precisely, a liquid crystal display module. For the liquid crystal display module in the embedded state, the window glass is combined to protect the liquid crystal panel.

Hereinafter, a configuration of a conventional mobile display device will be described in more detail with reference to the drawings.

1 is a cross-sectional view of a predetermined width of a side in which a light source is provided in a conventional mobile display device.

As shown, the conventional mobile display device 1 is a support main as a component for modularizing the liquid crystal panel 10 and the backlight unit 20 to display an image, and these two components (10, 20). The liquid crystal display module 5 including 30 and the cover bottom 50, the bottom cover set 60 for accommodating the liquid crystal display module 5, and the liquid crystal panel 10 are protected. For this purpose, the window glass 70 is further provided.

At this time, a resin layer 80 is provided between the window glass 70 and the liquid crystal panel 10, and the liquid crystal panel 10 and the window glass 70 are adhered to each other by the resin layer 80. By maintaining the state, they are preventing the flow of each other.

The window glass 70 has a larger area than the liquid crystal panel, in particular, has a larger length in the longitudinal direction. This covers the light source 29 and the support main 30 provided on one side of the light guide plate 23, which is a component of the liquid crystal panel 10 and the backlight unit 20, and at the same time covers the four side ends of the bottom cover set 60. It is to overlap with a predetermined width of and to be fixed in contact with it.

Further, one end of the window glass 70, more precisely, at one end of the portion exposed to the outside of the liquid crystal panel 10, is used as an adhesive means to fix the window glass 70 with respect to the bottom cover set 60. A double-sided tape 85 is provided.

However, when an external shock is applied to the conventional mobile display device 1 having such a configuration, that is, when the user drops while moving, it collides with the floor, and a strong external shock is applied, together with the window glass 70. A crack is generated in the liquid crystal panel 10 itself located under the liquid crystal panel 10 itself.

When an external shock is applied to the mobile display device 1 in this way, even if the window glass 70 is provided to protect the liquid crystal panel 10, cracks in the liquid crystal panel 10 are caused by an air gap ( air gap) exists.

In the liquid crystal panel 10, a first substrate 12 provided with an array element and a second substrate 14 provided with a color filter layer are bonded to each other through a liquid crystal layer (not shown). In order to drive the liquid crystal panel 10, a printed circuit board (PCB, not shown) equipped with a driving circuit is mounted, and such a printed circuit board (not shown) is a first substrate provided with the array element. One end of (12) is mounted through a flexible printed circuit board (FPCB) as an example of a flexible member (not shown).

Accordingly, the liquid crystal panel 10 is in a state in which one end of the first substrate 12 is exposed to the outside of the second substrate 14.

Furthermore, the liquid crystal panel 10 is disposed so that the second substrate 14 on which the color filter layer is provided is an upper surface so that the second substrate 14 faces the window glass 70.

In this way, the portion of the first substrate 12 exposed to the outside of the second substrate 14, more precisely, in the pad portion to which the flexible member (not shown) is attached, an air gap in the space between the window glass 70 and the air gap (air gap). gap) is being formed.

At this time, since the resin layer 80 overlaps and is provided only corresponding to the surface of the second substrate 14, air formed between the window glass 70 and the first substrate 12 when an external impact is applied. Particularly, in the portion where the air gap is formed by the gap, a strong impact is transmitted by vibration or the like, and cracks are frequent.

Furthermore, in addition to the flexible member (not shown), a driving circuit chip (not shown), etc., are further mounted on the pad portion in which the air gap is formed, and a problem that cracks are generated in the driving circuit chip (not shown) itself is caused. Actually.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a mobile display device capable of suppressing the occurrence of cracks in a liquid crystal panel even if an external impact occurs.

In order to achieve the above object, a mobile display device according to an embodiment of the present invention includes a support main, a liquid crystal panel having a predetermined width seated on the support main, and a backlight disposed under the liquid crystal panel. A bottom set cover having an inner groove into which the support main and the backlight unit are inserted, and having a horizontal portion and a vertical portion bent at the horizontal portion, and located above the liquid crystal panel and on the vertical portion of the bottom cover set It includes a window cover to be seated and a resin layer provided on the entire inner surface of the window cover and adhered to a vertical portion of the liquid crystal panel and the bottom cover set.

In this case, the liquid crystal panel includes a first substrate provided with a pad portion and a second substrate exposing the pad portion region, and the first substrate is preferably disposed to be positioned adjacent to the window cover. In this case, The resin layer is characterized in forming a structure that fills the spaced region between the first substrate and the support main.

In addition, first and second polarizing plates may be provided to correspond to both outer surfaces of the liquid crystal panel, and the first polarizing plate provided on the first substrate and the resin layer may contact each other. 1 A touch screen may be provided between the polarizing plate and the resin layer.

And it is preferable that the window cover is made of plastic.

As described above, in the mobile display device according to the present invention, a second substrate having a small area is located below and a first substrate having a large area is located above, so that the resin layer is provided on the front surface of the first substrate. As a result, the pad portion is also fixed by the resin layer, so that even if an external shock is applied, vibration or the like is suppressed in the pad portion, thereby suppressing the occurrence of cracks.

In addition, in the mobile display device according to an embodiment of the present invention, the process of attaching the double-sided tape is eliminated as the resin layer in contact with the first substrate becomes an adhesive means of the window cover and the bottom cover set instead of the double-sided tape. As it can be, there is an effect of shortening the modularization process.

Further, in the mobile display device according to an embodiment of the present invention, since the double-sided tape is removed, the resin layer itself becomes an adhesive means. When an external shock is applied, it has the effect of further suppressing the occurrence of cracks in the liquid crystal panel by removing the vibration factor.

In addition, the mobile display device according to the embodiment of the present invention has a configuration in which a resin layer is filled so that there is no air gap in the pad portion, so that the driving circuit chip, etc., which can be mounted through the flexible circuit board in the pad portion, is Covered by a layer and supported by a window cover and a guide panel, in this case, even if an external shock is applied, there is no air gap to generate vibration, so a crack occurs in the pad unit itself or the driving circuit chip itself. It has the effect of fundamentally preventing the phenomenon of becoming.

The backlight unit 120 includes a white or silver reflective plate 121, a light guide plate 123 mounted on the reflective plate 121, and a light source disposed corresponding to one side of the light guide plate 123 or both sides facing each other. It includes a phosphor LED assembly 129 and a plurality of optical sheets 125 interposed under the liquid crystal panel 110 above the light guide plate 123.

The LED assembly 129 is positioned on one side of the light guide plate 123 so as to face the side surface of the light guide plate 123.

On the other hand, in the mobile display device 101 according to the embodiment of the present invention, the backlight unit 120 is shown as an example that the LED assembly 129 is provided as a light source, but instead of the LED assembly 129 As a light source, a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp may be used as a light source.

The light guide plate 123 may include a specific shape pattern (not shown) on the rear surface to supply a uniform surface light source. Here, the pattern (not shown) may be configured in various ways such as an elliptical pattern, a polygon pattern, and a hologram pattern to guide the light incident into the light guide plate 123. In addition, such a pattern (not shown) is formed on the lower surface of the light guide plate 123 by a printing method or an injection method.

In addition, the reflective plate 121 is located on the lower surface of the light guide plate 123 and reflects the light passing through the lower surface of the light guide plate 123 toward the liquid crystal panel 110 to improve the luminance of light.

Further, the plurality of optical sheets 125 above the light guide plate 123 includes a diffusion sheet 125a and at least one light collecting sheet 125b, 125c, and the like, and diffuses or condenses the light passing through the light guide plate 123 Thus, a more uniform surface light source is incident on the liquid crystal panel 110.

On the other hand, the backlight unit 120 including the optical sheet 125 having such a configuration and the liquid crystal panel 110 positioned above the support main 130 and the liquid crystal display module ( 105).

The liquid crystal panel 110 and the backlight unit 120 are mounted so that the cover bottom 150, which is the basis for assembling the entire apparatus of the liquid crystal display module 105, may be formed of only a single plate-shaped horizontal surface of a square shape. At least one edge selectively with respect to the horizontal plane may be formed to have a side portion vertically bent at a predetermined height. In the drawing, it is shown as an example that the cover buttoum 150 is composed of only the horizontal plane.

Next, the support main 130 is also referred to as a guide panel or a mid frame, and the support main 130 has a rectangular frame shape formed by dividing the position of the liquid crystal panel 110 and the backlight unit 120 in the inside thereof. As a result, the liquid crystal panel 110 and the backlight unit 120 are surrounded by edges, and the cover bottom 150 is assembled and fastened.

The support main 130 having such a rectangular frame shape provides an area through which the LED assembly 129 is fixed by a method such as adhesion through one edge, and through this, a plurality of the LED assembly 129 The light emitted from the LED 129a serves to face one side of the light guide plate 123 forming the light-incident portion.

This support main 130 is characterized by being molded by injection.

On the other hand, in the mobile display device 101 according to the embodiment of the present invention, the window cover 170 is made of a plastic material with respect to the liquid crystal display module 105 having the above-described configuration. The layer 180 is reopened and provided in close contact, and a bottom cover set 160 for mounting the liquid crystal display module 105 is further provided.

The bottom cover set 160 includes a horizontal portion 160a forming a floor and a vertical portion 160b vertically bent at the horizontal portion 160a with predetermined widths of four corners of the horizontal portion 160a. In addition, on the upper surface of the vertical portion 160b, a stepped portion 161 on which an edge portion of the window cover 170 can be seated is provided.

At this time, as one of the most characteristic configurations in the mobile display device 101 having such a configuration, the liquid crystal panel 110, which is a component of the liquid crystal display module 105, includes an array element (not shown) and a pad unit. The second substrate 114 having the first substrate 112 provided with (PA) on it and having an area smaller than that of the first substrate 112 to expose the pad portion PA of the first substrate 112 It is characterized in that the first substrate 112 and the window cover 170 having a larger area are in close contact with each other through the resin layer 180 by having an arrangement configuration located at the lower portion thereof.

In this case, first and second polarizing plates 115a and 115b are provided on outer surfaces of the first and second substrates 112 and 114 of the liquid crystal panel 110, respectively. 1 A configuration in contact with the first polarizing plate 115a provided on the outer surface of the substrate 112 is formed.

In particular, the resin layer 180 includes a first polarizing plate 115a provided on an outer surface of the first substrate 112 and corresponding to the pad portion PA exposed to the outside thereof. It is characterized by being provided to the outer side of ). That is, the resin layer 180 is formed by filling a spaced area between the pad part PA of the first substrate 112 and the support main 130 facing it, so that an air gap is not formed in correspondence with this part. It is characterized by forming a structure that prevents it.

In this way, in the display device 101 for hair care according to an exemplary embodiment of the present invention, the first substrate 112 of the liquid crystal panel 110 is disposed so as to be bonded to the resin layer 180 when an external impact occurs. ) Is to suppress the vibration of the pad to suppress the crack of the pad part (PA).

In the case of a conventional display device for hair (1 of FIG. 1), a resin layer (80 of FIG. 1) is provided on a second substrate (14 of FIG. 1) with a color filter layer, so that when an external impact is applied, the resin layer The pad portion (PA of FIG. 1) of the first substrate (12 of FIG. 1) on which (80 in FIG. 1) was not formed was particularly vulnerable to crack generation as a relatively severe vibration was generated.

However, in the case of the mobile display device 101 according to the exemplary embodiment of the present invention, the second substrate 114 having a small area is located below and the first substrate 112 having a large area is located above the resin layer. As 180 is provided on the front surface of the first substrate 112, the pad part PA is also fixed by the resin layer 180, so that even if an external impact is applied, the pad part PA is In this case, the occurrence of cracks can be suppressed by suppressing vibration or the like.

Meanwhile, in the mobile display device 101 according to an exemplary embodiment of the present invention, the resin layer 180 includes the first substrate 112 and more precisely, the first polarizing plate 115a and a pad portion exposed to the outside thereof ( PA) is not provided only on the outer surface of the liquid crystal panel 110, but is provided to correspond to the entire surface of the window cover 170 having a larger area than the first substrate 112 of the liquid crystal panel 110. Another characteristic configuration is that 180) itself serves as an adhesive layer and becomes an adhesive means for fixing the window cover 170 to the bottom cover set 160.

In the conventional mobile display device (1 in FIG. 1), a double-sided tape (85 in FIG. 1), which is a separate adhesive, is used to fix a window glass (70 in FIG. 1) and a batt cover set (60 in FIG. 1). Used. In this case, the step of attaching the double-sided tape (85 in FIG. 1) to the bottom cover set (60 in FIG. 1) or the window glass (70 in FIG. 1) needs to be further performed. ), the productivity per unit time was decreased by increasing the process time of modularization.

Moreover, since the double-sided tape (85 in Fig. 1) has a predetermined thickness, the window glass (70 in Fig. 1) and the bottom cover set (60 in Fig. 1) are fixed by the double-sided tape (85 in Fig. 1). In case of height deviation, a fine gap exists between the resin layer (80 in FIG. 1) and the liquid crystal panel (10 in FIG. 1) provided in the window glass (70 in FIG. 1), which is vibrated when an external shock is applied. The occurrence of this became a factor causing cracks in the liquid crystal panel (10 in FIG. 1).

However, in the mobile display device 101 according to an embodiment of the present invention, the resin layer 180 in contact with the first substrate 112 replaces the conventional double-sided tape (85 in FIG. 1) and the window cover ( 170) and the bottom cover set 160, the process of attaching the double-sided tape (85 in Fig. 1) can be eliminated, so that the modularization process is shortened, and the double-sided tape (85 in Fig. 1) is eliminated. As a result, since the resin layer 180 itself becomes an adhesive means, a fine gap between the resin layer 180 and the liquid crystal panel 110 provided in the window cover 170 caused by a thickness deviation of the double-sided tape (85 in FIG. 1) is When an external shock is applied as it is suppressed by nature, the occurrence of cracks in the liquid crystal panel 110 is further suppressed by removing a vibration factor.

In the case of the mobile display device 101 according to the exemplary embodiment of the present invention, the resin layer 180 provided between the window cover 170 and the liquid crystal panel 110 is larger than the liquid crystal panel 110, that is, In response to the window cover 170, the resin layer 180 is formed on the first substrate 112 due to a property provided on the front surface thereof and a liquid property having a predetermined viscosity before the resin layer 180 is cured. The portion located outside of the liquid crystal panel 110 moves to the pad portion PA of the liquid crystal panel 110, and thus, is filled up to the pad portion PA of the first substrate 112, so that the window cover 170 and The resin layer 180 is filled without an air gap between the liquid crystal panel 110 and the liquid crystal panel 110.

The resin layer 180 is formed by adjusting the thickness of the portion formed outside the liquid crystal panel 110, that is, when the resin layer 180 is formed, the liquid crystal panel 110 is compared to the portion corresponding to the liquid crystal panel 110. The resin layer 180 is moved toward the pad portion PA of the first substrate 112 before the resin layer 180 is cured by forming the outer region of the resin layer to have a relatively larger thickness. The layer 180 is filled to fill the air gap.

When the resin layer 180 is filled with the pad part PA in this way, a driving circuit chip (not shown) that can be mounted through a flexible circuit board that is a flexible member (not shown) in the pad part PA, etc. Is supported by the window cover 170 and the support main 130 while being covered by the resin layer 180. In this case, even if an external shock is applied, there is no air gap to generate vibration. The phenomenon that cracks are generated in the furnace chip (not shown) is fundamentally prevented.

The mobile display device 101 according to an embodiment of the present invention having such a configuration includes a window glass (70 in FIG. 1) and a liquid crystal panel (10 in FIG. 1) provided in a conventional mobile display device (1 in FIG. 1). ) Between the air gap (AG in FIG. 1) is essentially removed by the resin layer 180, so that cracks in the liquid crystal panel 110 due to external impact, especially the pad part of the first substrate 112 It has the effect of fundamentally preventing the occurrence of cracks in (PA).

Meanwhile, in the drawing, a resin layer 180 is provided between the window cover 170 and the liquid crystal panel 110 as an example, but the mobile display device 101 is further provided with a touch screen to implement a touch function. The touch screen may be positioned between the liquid crystal panel 110 and the window cover 170.

When the case further including such a touch screen is referred to as a mobile display device according to a modified example of the embodiment of the present invention, Fig. 4 (a predetermined light source provided with a light source of the mobile display device according to the modified example of the embodiment of the present invention) As shown in the cross-sectional view of the width), the mobile display device 201 according to the modified example of the embodiment of the present invention includes a first polarizing plate 115a on the first substrate 112 of the liquid crystal panel 110. Is provided, and the touch screen 190 is provided by resuming an adhesive layer (not shown) on the first polarizing plate 115a, and a window cover ( 170) is located.

In this case, since the touch screen 190 is provided only in an area displaying an image, it has a smaller area than the first substrate 112, and the resin layer 180 is It includes the outer surface of the first substrate 112 that is exposed to the outside and is formed to a portion where the butt cover set 160 is located.

In the case of the mobile display device 201 according to the modified example of the embodiment of the present invention, other configurations other than the configuration that the touch screen 190 is further provided are the mobile display device according to the embodiment of the present invention (Fig. Since it is the same as 101) of 2, a detailed description thereof will be omitted.
