In addition, since the second portion 122 is arc-shaped, the display portion 110 can smoothly transit to the first portion 121, thereby effectively avoiding the connecting portion 120 from being damaged due to excessive bending.
In this embodiment, since the second portion 122 is arc-shaped, a certain gap is formed between the display portion 110 and the first portion 121, and the gap can be well filled and supported by the thickness of the heat dissipation layer 30, so as to prevent the second portion 122 from being excessively bent and damaged. If the heat dissipation layer 30 only includes the heat dissipation plate 310, the thickness of the heat dissipation plate 310 may be adjusted as needed so that only the thickness of the heat dissipation plate 310 may satisfy the need. If the heat dissipation layer 30 includes the heat dissipation plate 310 and the support plate 320, the thicknesses of the heat dissipation plate 310 and the support plate 320 are adjusted as needed so that the sum of the thicknesses of the heat dissipation plate 310 and the support plate 320 can satisfy the need.
