When the engaging member 117 and the positioning hole 125 are engaged with each other, the user can insert into the detaching hole 118 by using a detaching tool (for example, a screwdriver), but it is not inserted into the opening 126 of a smaller size. Then, the detaching tool is abutted against the opening 126 and horizontally rotated relative to the display panel 120. At this time, the detaching tool is stretched between the outer frame 112 and the display panel 120 to disengage the engaging member 117 from the positioning hole 125. The vertical position of the engaging member 117 is not restricted by the positioning hole 125, and the engagement between the display panel 120 and the outer frame 112 is smoothly released.

In addition, the fascia 130 is fixed between the display panel 120 and the lower frame 114, and the fascia 130 is provided with an opening 134 corresponding to the position of the detaching hole 118 (ie, The second opening) may have a size larger than the size of the detaching hole 118 and at least larger than the size of the detaching tool. In practice, the user can directly insert the removal tool into the removal hole 118 and the opening 134, and then perform the above-mentioned removal procedure to release the buckle.

Referring to FIGS. 2A and 2B , in particular, the trim panel 130 has a front panel portion 131 and a side panel portion 132 . The front plate portion 131 extends in parallel on the display surface of the display panel 120 to cover one side of the display surface of the display panel 120. As shown in FIG. 1C, although the front plate portion 131 covers the lower region of the display surface 120D, the lower region is generally not included in the visible region (because the plastic frame 104 forms an invisible region behind the display surface 120D), The area of the visible area that affects the display surface 120D.

In addition, the side plate portion 132 is sandwiched between the lower frame 114 and the display panel 120 to fix the fascia 130. In addition, the side plate portion 132 can also be fixed to the inner side of the outer frame 112 by at least one fixing member 136. The fixing member 136 is, for example, a screw, and can penetrate the lower frame 114 and the side plate portion 132. As shown in FIG. 2C, the lower frame 114 has a plurality of first through holes 119, and the side plate portion 132 has a plurality of second through holes 135. The first through holes 119 are opposite to the positions of the second through holes 135, and the aperture thereof is The size is substantially equivalent to the shaft diameter of the fixing member 136. The first through hole 119 and the second through hole 135 are, for example, screw holes. Each of the fixing members 136 can penetrate the corresponding first through hole 119 and the second through hole 135 and fix the side plate portion 132 on the inner side of the lower frame 114.

In an embodiment, the fascia 130 is a grounded metal plate that can conduct current to the ground or large area of the metal back cover 111 to avoid the moment of static concentration. The current flows into the display and destroys the electronic components inside the display. Therefore, the fascia 130 can increase the ability of the display panel 120 to resist electrostatic discharge (ESD).

Further, in FIGS. 1A and 1C, the front plate portion 131 of the fascia 130 is almost coplanar with the front edge of the outer frame 112, so that the fascia 130 is not protruded from the lower frame 114. From the overall visual point of view, not only can a full-planar appearance be achieved, but the overall thickness of the display becomes thinner to meet the requirements for thinning. In addition, the fascia 130 may be an aluminum plate, a stainless steel plate or a galvanized iron plate, etc., and the surface of the fascia 130 may be anodized or a laminated color metal as a fascia 130 to increase metallic luster, color and pattern. In addition, when the display panel 120 is provided with a heat source such as a circuit board or a backlight on the inner side of the fascia 130, the fascia may absorb heat and the temperature rises. At this time, the outer surface of the fascia 130 may further form a heat insulation layer 130a. For example, it is an insulating rubber or a PC plastic material to reduce the surface contact temperature of the fascia 130. Therefore, when the user touches the fascia 130, the surface temperature of the fascia 130 can be prevented from being too high and has a burning sensation.

The frameless display and the fascia thereof disclosed in the above embodiments of the present invention use the thinned outer frame as the outer frame of the display panel and do not cover the display surface of the display panel. Therefore, the display surface of the display panel can be completely rendered without shrinking the visible area of the display surface due to the conventional outer frame covering the surrounding surface of the display panel. In addition, the front plate portion of the plaque extends parallel to the display surface of the display panel, which can increase the visual effect, increase the anti-electrostatic discharge (ESD) capability of the display panel, and realize a full-planar appearance, so that the overall thickness of the display becomes Thinner to meet the requirements of thinning.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
