Abstract
The invention relates to a modularized flat display unit, comprising casing, display screen, display screen-drive functional module and external terminals, where the functional module is arranged in a box, and the box is removably installed on one side of the casing, and the external terminals are arranged on one side of the box. Thus, it reduces the design cost, and makes maintenance convenient. Besides, the external terminals are inclinedly arranged on the box to be able to effectively reduce parts of the wire projecting from the box so as to reduce the required installation space for the flat display unit; the flat display unit further adopts ''T''-shaped support device to effectively use vertical and cross bars to support the whole display unit, solving the problem that the support strength is not enough.
Description
Technical field
The present invention relates to a kind of display device, more particularly, relate to a kind of panel display apparatus.
Background technology
Panel display apparatus (for example LCD, LCD TV etc. are example below with the LCD) is the display device that the principle of utilizing the orientation meeting of liquid crystal molecule to change incident light polar biased direction is designed.Because but superior functions such as the LCD space is little, plate thickness is thin, flat square demonstration in light weight, low power consumption, no electromagenetic wave radiation, non-thermal radiation make LCD replace CRT (Cathode Ray Tube) display gradually.And, the development that the technology of LCD is also just swift and violent.
Along with the function of LCD is more and more, the functional module that is installed in LCD inside is also more and more.The structure of existing LCD as shown in Figure 1, its display screen 11 is installed in the front side of shell 12; And functional module 13 (for example power module, display screen driver module, signal processing module etc.) is directly installed in the shell 12, and is electrically connected by the interface or the circuit board of correspondence.After by functional module 13 external signal being handled, on display screen 11, show.There is following shortcoming at least in the LCD of this structure: 1, when certain functional module in the LCD breaks down, user or maintenance person need to move whole LCD to maintenance ground from making land used, make and keep in repair very inconvenience; And along with the size of LCD is increasing, moves whole LCD and become more and more difficult, bring great inconvenience to maintenance.2, be subjected to the restriction of shell easily in the enclosure in assembling or maintenance process because functional module is directly fixing, influence assembling or maintenance can not be carried out smoothly, have reduced efficient.3, in order to meet the different needs, the size of LCD can be designed to a plurality of specifications, corresponding shell also is designed to a plurality of sizes, thereby the functional module that is directly installed in the shell also needs to be designed to a plurality of specifications, to cooperate the size of shell, make design, production cost become very high.
The rear portion of the shell of traditional flat-panel monitor has backboard and external terminal, and that the mounting means of external terminal is shown greatly is as described below.Wherein a kind of is that external terminal is installed in the backboard edge, and the angle of the angle of external terminal and backboard is roughly 180 °.Yet owing to have the input/output interface of difference in functionality on the external terminal mostly, for example electric source line interface, video input interface, audio input interface, cable of cable TV interface and S terminal interface are in order to the wire rod of cooperation difference in functionality.The mounting means of this external terminal will make the backboard of the outstanding flat-panel monitor of wire rod, and then make the required space of installation flat-panel monitor become big.
Therefore, the fluted body external terminal promptly develops this problem that solves.The fluted body external terminal is installed on the edge of flat-panel monitor, and input/output interface then is installed on the face of fluted body external terminal.If input/output interface is installed on the one side perpendicular to backboard of fluted body external terminal, because the user can't see these input/output interfaces, and then makes the installation difficulty of wire rod when these wire rods are installed.And the fluted body external terminal will cause the flat-panel monitor inner space to reduce, and then make the inner space configuration difficulty of flat-panel monitor.
Traditional LCD group still is made of LCD and chassis mostly.Wherein, the chassis is installed in the root edge of LCD, in order to support the weight of LCD.Yet along with liquid crystal panel develops towards large scale, the weight of LCD is also more and more heavier.It is not enough that the support strength that traditional chassis can provide also seems, particularly for LCD TV, because it emphasizes large-sized characteristic, so its center of gravity is also just more and more higher.And because traditional chassis only is installed on the root edge of LCD, if this traditional chassis is installed on the more and more higher LCD TV of center of gravity, it is not enough that its support strength and fiduciary level often seem.
Summary of the invention
