1. A complete machine structure, comprising a display module and a complete machine exterior frame, wherein the display module comprises a display panel and a front frame, the front frame comprises a front frame side edge on an outer side of a side edge of the display panel; the complete machine exterior frame comprises at least one outer frame side edge each located on a side of the front frame side edge away from the display panel, and in contact with the front frame side edge, and a total contact area of all outer frame side edges and corresponding front frame side edges satisfies:

OG Complex Work Unit Math
where S is the total contact area; L is a maximum width of the outer frame side edge at a position where the outer frame side edge is in contact with the front frame side edge in a direction perpendicular to a contact surface of the outer frame side edge with the front frame side edge; P is a power of the display module, which is a sum of a power of the display panel and a power of a backlight module of the display module; K is a heat conductivity coefficient of the outer frame side edge; T1 is a temperature of the display module at an ambient temperature of 20° C., wherein the temperature of the display module is defined as an actual temperature of the display module detected on a printed circuit board thereof at a preset ambient temperature when the display module of the complete machine structure is turned on to present a static image and reaches a temperature stable state; T2 is a maximum allowable temperature on a surface of the outer frame side edge away from the display module at an ambient temperature of 20° C.; and
T2 is less than or equal to 50° C.
