When the frame 210 is composed of the first sub-frame 212 and the second sub-frame 214, the two sub-frames may be made of different materials. The frame 210 may be formed by plastic injection molding, aluminum magnesium alloy injection molding, aluminum extrusion, or other techniques.
Fig. 5 is a rear view of the display device of fig. 1 with the appearance back cover removed. Referring to fig. 2, the edge of the touch pad 230 of the present embodiment has two flexible flat cables 232, but there may be more or only one flexible flat cable on the touch pad 230. Referring to fig. 2 and 3, the frame 210 further has a wire outlet P10. The cable port P10 is located in the second carrying recessed region R14, and the position of the cable port P10 corresponds to the position of the flexible cable 232. The flex cable 232 passes through the cable port P10 to avoid the flex cable from being scratched by the exposed bent portion, because the flex cable is the weakest and easily abraded portion at the bent portion. A rear view of the flex cable 232 after passing through the cable port P10 is shown in fig. 5. By designing the cable port P10, the flexible cable 232 can be hidden behind the display panel 220 and covered by the viewing back cover 260.
