Display devices have been widely applied to various electronic equipment in which messages or pictures need to be displayed, such as notebook computers and personal computers. Because a typical display device has an optimal viewing angle, it is desirable that the display device can be inclined forward or backward to attain the optimal viewing angle for any particular user.
Referring to FIG. 9, a conventional display device 1 includes a base 11, a pivot mechanism 12, and a display module 13. The base 11 includes a pair of symmetrical first supporting stands 110, each of which has a lock axle 111 for pivoting the display module 13 to the first supporting stands 110. The pivot mechanism 12 includes a first pin 120, a bolt 121, a supporting shelf 123, and a second supporting stand 124. The supporting shelf 123 has a hole 125. The supporting shelf 123 is pivoted on the second supporting stand 124 by means of engagement of the first pin 120 in the hole 125. The display module 13 has a second pin 130. The bolt 121 is pivotably attached with the second pin 130 through the supporting shelf 123.
Referring also to FIG. 10, when the bolt 121 is rotated by a user, the pivot junction of the bolt 121 and the second pin 130 pushes the second pin 130 forward. Simultaneously, the supporting shelf 123 is slightly rotated about the first pin 120 and thus the second supporting stand 124. Accordingly, the display module 13 is rotated forward about the lock axle 111. When the bolt 121 is rotated and screwed into the supporting shelf 123, the display module 13 is rotated forward. When the bolt 121 is screwed out from the supporting shelf 123, the display module 13 is rotated backward.
However, the display module 13 is rotated about the base 11 by means of manually rotating the bolt 121, which is in an unduly laborious and inconvenient operation. Moreover, because the pivot mechanism 12 is a separate assembly located outside the display device 1, a total volume occupied by the display device 1 is in effect increased.
Therefore, a new display device that can overcome the above-described problems is desired.
