I W VI. Description of the Invention: TECHNICAL FIELD The present invention relates to an electronic device, and more particularly to a display device. [Prior Art] With the advancement of display technology, a flat display device has been developed. Flat-panel displays have the advantages of small size, light weight, and versatile size, making flat-panel display devices a complete replacement for traditional cathode ray tube (CRT) displays. The flat display is composed of components such as a backlight unit and a display unit. After the panel manufacturer completes the display unit, the backlight unit is combined with the display unit through the module process to form a panel module. The panel module is then sent to the system assembler to assemble peripheral components such as the housing, board, buttons, and connectors to complete a TV, computer screen, or mobile phone. However, the life of the backlight unit and the display unit are not the same. When one of them is damaged, the entire panel module (including the backlight unit and the display unit) must be scrapped. And the display unit can only be used with the backlight unit set by the panel manufacturer, and no flexibility is used. SUMMARY OF THE INVENTION The present invention relates to a display device that utilizes a display panel module and a backlight module to selectively combine or separate designs, so that the user can freely match the display panel module and the backlight module. Improve the use of display devices. And in the display panel module and the backlight module

The display device includes a display panel module and a backlight module. The display panel module includes a display panel unit, a housing and an opaque control circuit. The display panel unit has several pixels. One of the front surfaces of the display panel unit is divided into a display area and a non-display area. The rear surface of one of the display panel units is divided into a light incident area and a non-light incident area. The self-lighting region extends along a light propagation path toward the display region to form a light propagation space. The halogen elements are correspondingly placed in the display area. The housing includes a first coupling mechanism, and the housing encloses the non-display area of the display panel unit and a portion of the non-light-in area. The opaque control circuit receives an external video signal to selectively turn each of the pixels on or off to form an image on the front surface of the display panel unit. The control circuit is disposed in the housing and outside the light propagation space, and a light incident from any point in the light incident region travels straight through the display panel unit to reach the display area. The backlight module includes a backlight unit and a second bonding mechanism. The backlight unit has a light emitting area. The second bonding mechanism is for selectively combining or separating the first bonding mechanism. When the first bonding mechanism is combined with the second bonding mechanism, the backlight module is located behind the display panel module, and the light emitting region of the backlight unit corresponds to the light entering region of the display panel unit. In order to make the above description of the present invention more comprehensible, the various embodiments of the present invention are described in detail below with reference to the accompanying drawings. 201239834

The IW7389FA selectively combines or separates the display panel module and the backlight module to enable the user to freely match the display panel module and the backlight module to enhance the diversification of the display device. And when one of the display panel module and the backlight module is damaged, it is only necessary to replace the damaged portion. However, the examples are for illustrative purposes only and are not intended to limit the scope of the invention. Further, the drawings in the embodiments are omitted to partially illustrate the technical features of the present invention. The first embodiment shows a schematic view of the display device 100 of the first embodiment in a separated state, and FIG. 2 shows a rear view of the display panel module 110 of the second embodiment. . The display device 1 of the embodiment includes a display panel module 110 and a backlight module 12A. The display panel module 110 of this embodiment does not include any light source. The display panel module 11A can be selectively combined or separated from the backlight module 120. The display panel module 110 can be coupled to different backlight modules 12A to display the kneading surface by using the light provided by the backlight module 120. In terms of the structure of the display panel module 110, the display panel module 11A to >' includes a display panel unit 1A, a housing 112, and an opaque control circuit 113 (shown in FIG. 2).

As shown in Fig. 2, the rear surface of one of the display panel units 111 is divided into a light incident area BS1 and a non-light incident area BS2. The self-light-in area BS1 extends along a light transmission 201239834, and the path D1 extends toward the display area FS1 to form a light propagation space s, which is correspondingly disposed in the display area BS1 and located in the light propagation space s. The double body 112 covers the non-display area FS2 of the display panel unit U1 and a portion of the non-light-in area BS2 to expose the display area FS1 and the light-in area BS1. Thereby, the light can be incident on the light propagation space S from the light incident path w from the light incident region W, and then emitted from the display region FS1. In addition, the housing 112 includes a first bonding mechanism M11 (the first bonding mechanism Mil of the present embodiment is exemplified by a rail) for selectively combining with the backlight module 12A. The opacity control circuit 113 receives an external video signal IS to selectively turn each pixel on or off.
