Abstract

The present invention provides a backplane and a liquid crystal module having the backplane. The backplane includes a main body, a plurality of raised ribs formed on the main body, and a plurality of wall mounting members rotatably attached to the raised ribs. Each of the wall mounting members is selectively set, through rotation, at a retracted position or a wall-mountable position with respect to the corresponding raised rib. The wall mounting members provided on the backplane of the liquid crystal module are made in a foldable arrangement, whereby in packaging, the wall mounting members are rotated to a retracted position located inside the backplane and in an operation of assembling a complete device, the wall mounting members are expanded to a wall-mountable position for use.

Claims

1. A backplane, comprising:

a main body, a plurality of raised ribs formed on the main body, and a plurality of wall mounting members rotatably attached to the raised ribs, each of the wall mounting members being selectively set, through rotation, at a retracted position or a wall-mountable position with respect to the corresponding raised rib;

wherein each of the raised ribs forms a plurality of receiving slots and each of the receiving slots comprises a mounting section and a receiving section communicating with the mounting section, the mounting section having two opposite edges from which a pair of mounting tabs respectively extends in a direction opposite to a direction in which the raised rib is raised, each of the wall mounting members being rotatably mounted to each of the mounting sections in such a way that when the wall mounting member is in the retracted position, the wall mounting member is completely received in the receiving section and when the wall mounting member is in the wall-mountable position, the wall mounting member projects outward in the direction in which the raised rib is raised; and

wherein each of the mounting tabs forms a mounting hole and each of the wall mounting members is of a U-shape having two limbs each having an outward-facing surface forming a pivot pin at a location close to a free end thereof, the pivot pins being respectively receivable in the mounting holes so as to rotatably attach the wall mounting member to the mounting tabs.

2. The backplane as claimed in claim 1, wherein the wall mounting member is made of a spring plate and the mounting tabs extend in a direction that is opposite to the direction in which the raised rib is raised, the two paired mounting tabs being spaced by a distance that is greater than a width of the corresponding receiving section measured in a direction along the distance.

3. The backplane as claimed in claim 1, wherein the raised ribs have a number of two and each of the raised ribs forms two receiving slots.

4. The backplane as claimed in claim 1, wherein each of the wall mounting members has a central section in which a through hole is formed.

5. A backplane, comprising:

a main body, a plurality of raised ribs formed on the main body, and a plurality of wall mounting members rotatably attached to the raised ribs, each of the wall mounting members being selectively set, through rotation, at a retracted position or a wall-mountable position with respect to the corresponding raised rib;

wherein each of the raised ribs forms a plurality of receiving slots and each of the receiving slots comprises a mounting section and a receiving section communicating with the mounting section, the mounting section having two opposite edges from which a pair of mounting tabs respectively extends in a direction opposite to a direction in which the raised rib is raised, each of the wall mounting members being rotatably mounted to each of the mounting sections in such a way that when the wall mounting member is in the retracted position, the wall mounting member is completely received in the receiving section and when the wall mounting member is in the wall-mountable position, the wall mounting member projects outward in the direction in which the raised rib is raised;

wherein each of the mounting tabs forms a mounting hole and each of the wall mounting members is of a U-shape having two limbs each having an outward-facing surface forming a pivot pin at a location close to a free end thereof, the pivot pins being respectively receivable in the mounting holes so as to rotatably attach the wall mounting member to the mounting tabs;

wherein the wall mounting member is made of a spring plate and the mounting tabs extend in a direction that is opposite to the direction in which the raised rib is raised, the two paired mounting tabs being spaced by a distance that is greater than a width of the corresponding receiving section measured in a direction along the distance;

wherein the raised ribs have a number of two and each of the raised ribs forms two receiving slots; and

wherein each of the wall mounting members has a central section in which a through hole is formed.

6. A liquid crystal module, comprising:

a backplane, a backlight module arranged inside the backplane, and a liquid crystal panel arranged above the backlight module, the backplane comprising;

a main body, a plurality of raised ribs formed on the main body, and a plurality of wall mounting members rotatably attached to the raised ribs, each of the wall mounting members being selectively set, through rotation, at a retracted position or a wall-mountable position with respect to the corresponding raised rib;

wherein each of the raised ribs forms a plurality of receiving slots and each of the receiving slots comprises a mounting section and a receiving section communicating with the mounting section, the mounting section having two opposite edges from which a pair of mounting tabs respectively extends in a direction opposite to a direction in which the raised rib is raised, each of the wall mounting members being rotatably mounted to each of the mounting sections in such a way that when the wall mounting member is in the retracted position, the wall mounting member is completely received in the receiving section and when the wall mounting member is in the wall-mountable position, the wall mounting member projects outward in the direction in which the raised rib is raised; and

wherein each of the mounting tabs forms a mounting hole and each of the wall mounting members is of a U-shape having two limbs each having an outward-facing surface forming a pivot pin at a location close to a free end thereof, the pivot pins being respectively receivable in the mounting holes so as to rotatably attach the wall mounting member to the mounting tabs;

the wall mounting member is made of a spring plate and the mounting tabs extend in a direction that is opposite to the direction in which the raised rib is raised, the two paired mounting tabs being spaced by a distance that is greater than width of the corresponding receiving section measured in a direction along the distance; and

each of the wall mounting members has a central section in which a through hole is formed.

7. The liquid crystal module as claimed in claim 6, wherein the raised ribs have a number of two and each of the raised ribs forms two receiving slots.
