Description

Dual type LCD module fixing structure of portable wireless terminal {FIXING STRUCTURE FOR DUAL TYPE LCD MODULE IN PORTABLE RADIOTELEPHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual type liquied crystal display module, and in particular, a dual type LCD module fixing structure of a portable wireless terminal configured to minimize the thickness of the dual LCD module located between the rear cover and the front cover. To provide.

As portable wireless terminals become more and more popular, terminals of various functions and designs are appearing. In addition, as the terminal becomes smaller and lighter and shorter, the variety of functions is more highlighted. Therefore, in order to satisfy the needs of the consumers as described above, there is an emphasis on reducing the volume of the terminal to the maximum while maintaining or improving the function.

Recently, in the standby mode of a folder type terminal, a terminal having a dual type LCD module attached to a separate LCD module on the outside of a folder has been released to compensate for the disadvantage that the LCD module installed inside the folder cannot be identified.

1 is a perspective view of a portable wireless terminal having a general dual type LCD, a main body 110 consisting of upper and lower casing frames, and a folder 120 installed to be opened and closed by a predetermined hinge operation in the main body 110. And a keypad unit 140 having a display device (LCD module) 130 installed on the folder, a plurality of key buttons installed on a main body for inputting data into the display device, and a main body installed on the main body. It consists of an antenna device 150.

The LCD module 130 is an auxiliary LCD installed on the outer surface of the folder, but is not shown, but has a configuration in which the main LCD is installed on the inner surface of the folder 120.

Figure 2 is a partial cross-sectional view showing a dual type LCD module fixing structure according to an embodiment of the prior art, the dual type LCD module is installed between the front cover 121 and the rear cover 122 of the folder. Between the rear cover 122 and the front cover 121, the printed circuit board 40 is installed on both sides of the main LCD 42 and the slave LCD 41 is fixed by electrical connection. In addition, on each cover 121 and 122 corresponding to each of the LCDs 41 and 42, a main LCD window 132 and a slave LCD window 131 are respectively installed to prevent foreign substances from entering. . The portions on which the LCD windows 131 and 132 of the covers 121 and 122 are mounted are formed to have a step, and the LCD windows 131 and 132 are mounted on each of the step portions to be double-sided adhesive tapes or bonds. Bonded

At this time, the main LCD 42 and the slave LCD 41 are in contact with the lower side of the step portion for mounting the LCD window 132, 131 of each cover (122, 121), a predetermined cushioning material therebetween. By placing the 52 and 51, the LCD of the terminal is prevented from being damaged by an external shock.

However, as shown in FIG. 2, since the main LCD and the slave LCD are in contact with the lower surface of the stepped portion of the rear cover and the front cover, respectively, the space is separated by the thickness of the step portion of the cover frame between the LCD window and the LCD. As a result, a gap is generated, and this unnecessary gap increases the total volume of the terminal, thereby causing a problem that is gradually reversed to the terminal market which is becoming smaller and thinner.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a dual type LCD module fixing structure of a portable wireless terminal configured to reduce the total volume of the terminal by reducing the maximum number of the LCD module mounting structure between the rear cover and the front cover. have.

Another object of the present invention is to provide a dual type LCD fixing structure of a portable wireless terminal that can minimize the volume of the terminal at the same time a plurality of buffers are inserted into the main portion that can withstand the external impact as much as possible.

21: front cover 22: rear cover

40: printed circuit board 41: slave LCD

42: main LCD 51, 52, 61, 62: buffer

In order to achieve the above object, the present invention mounts a dual type LCD including a main LCD and a slave LCD between a rear cover and a front cover of a folder, and displays the LCD through an LCD hole formed on each cover. In the portable wireless terminal to configure,

Each of the LCDs may be formed smaller than the LCD holes of the respective covers so as to be close to the LCD windows mounted in the LCD holes.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the case where it is determined that the gist of the present invention may be unnecessarily obscured, the detailed description thereof will be omitted.

3 is a partial cross-sectional view showing a dual type LCD module fixing structure according to an embodiment of the present invention, which is interposed between a rear cover 22 and a front cover 21 of a folder. .

The LCD module includes two LCDs electrically connected to and fixed on the printed circuit board 40, that is, a mail LCD 42 and a slave LCD 41 are connected to the PCB. 40 are respectively provided to be electrically connected to both surfaces. In other words, each of the LCDs 42 and 41 is a main LCD 41 that can be displayed through the main LCD window 132 installed in the rear cover 22 and a slave LCD installed in the front cover 21. It is composed of a slave LCD 42 that can be displayed through the window (131).

At this time, each of the LCD window (132, 131) is mounted on the main LCD hole 72 and the slave LCD hole 71 formed in each cover (22, 21), to prevent foreign matter from entering the terminal It protects each LCD module. The LCD windows 132 and 131 are attached to the LCD holes 72 and 71 formed so that the edges of the rear cover 21 and the front cover 22 are stepped, and are fixed by predetermined bonding means or double-sided adhesive tape. Can be.

In the present invention, each of the LCD (72, 41) is installed to be as close as possible to the corresponding respective LCD window (132, 131), thereby minimizing the thickness of the terminal folder. Accordingly, the main LCD 42 and the slave LCD 41 are formed to be at least smaller in size than the respective CD holes 72 and 71.

Preferably, as shown in FIG. 3, the LCDs 42 and 41 are made smaller than the LCD holes 72 and 71 so that the LCD is partially inserted into the LCD holes. At this time, a predetermined buffer material 52, 51 is provided between each of the LCD windows 132 and 131 and the LCDs 42 and 41 so as to withstand the impact from the outside. The buffers 52 and 51 may be made of materials such as poron, rubber, urethane, silicone, woven fabric, sponge, or the like, and other buffers may be used.

More preferably, when applying the shock absorbing material (52, 51), by inserting a separate shock absorbing material (62, 61) between the printed circuit board and each cover to configure a double buffer structure to reduce the resistance to external impact of the terminal You can stretch it as much as possible.

As described above, the LCD module fixing structure according to the embodiment of the present invention can close the LCD window and the LCD as close as possible, and apply the double buffer structure to reduce the volume of the terminal as much as possible.
