2. Description of the Related Art

In prior art, the manufacture material of a thin film transistor (TFT) primarily includes inorganic materials such as silicon (Si) and germanium (Ge). Comparing the inorganic materials with organic semiconductors, a carrier mobility of the inorganic materials is higher than the carrier mobility of the organic semiconductors for three magnitudes. Thus, most of active display devices adopt inorganic semiconductor especially amorphous silicon (a-Si) TFT as a driving member thereof. Due to a-Si TFT has advantages of that it has function of controlling the delivery of pixel signals and can be manufactured in low temperature, the driving member used with the a-Si TFT becomes a mainstream in the market.

DETAILED DESCRIPTION

The present invention provides a novel driving member for liquid crystal display (LCD) that integrates a design of active driving member with a theory of micro-electro-mechanical system (MEMS). The design of active driving member primarily is for controlling an action of a pixel in a corresponding position, and the use of MEMS is primarily for integration of mechanical electronics such as switch valve, brake and motor.

FIG. 1 shows a perspective view of a driving member 100 in the present invention. The driving member 100 includes a first suspending beam module 101, a conductive suspending beam module 102, and a second suspending beam module 103. The first suspending beam module 101 can be made of a-Si, or any conductive metal or alloy. The first suspending beam module 101 includes a first suspending beam 104 and a first suspending beam holding terminal 107. The first suspending beam holding terminal 107 is arranged at one end of the first suspending beam 104. The first suspending beam holding terminal 107 is wider than the first suspending beam 104.

The conductive suspending beam module 102 is arranged between the first suspending beam module 101 and a second suspending beam module 103. The conductive suspending beam module 102 can be made of any conductive metal or alloy. The conductive suspending beam module 102 includes a conductive suspending beam 105 and a conductive suspending beam holding terminal 108. The conductive suspending beam 105 is extended from the conductive suspending beam holding terminal 108, and one end of the conductive suspending beam 105 is bended towards the first suspending beam 104.

The second suspending beam module 103 can be made of a-Si, or any conductor metal or alloy. The second suspending beam module 103 includes a second suspending beam 106 and two second suspending beam holding terminals 109 arranged at both ends of the second suspending beam 106. Each of the second suspending beam holding terminals 109 is wider than the second suspending beam 106.

FIG. 2A shows a top view of the driving member 100 in an original state in accordance with a first embodiment of the present invention. In the original state, the first suspending beam 104, the conductive suspending beam 105 and the second suspending beam 106 are all in suspending states. In use, a voltage can be provided between the first suspending beam 104 and the second suspending beam 106, so that the first suspending beam 104 moves to electrically contact with the conductive suspending beam 105.

FIG. 2B shows a top view of the driving member 100 shown in FIG. 2A provided with a voltage. When the voltage is provided between the first suspending beam 104 and the second suspending beam 106, electrical signals are transmitted from the first suspending beam holding terminal 107 and the second suspending beam holding terminals 109 respectively to the first suspending beam 104 and the second suspending beam 106. Due to an electric field attractive force formed between the first suspending beam 104 and the second suspending beam 106 is larger than a deforming force threshold of the first suspending beam 104, the first suspending beam 104 moves towards the second suspending beam 106 to electrically contacted with the conductive suspending beam 105, so that neighboring conductive suspending beam 105 and first suspending beam 104 are short circuited, and the neighboring conductive suspending beam 105 has a voltage same with the first suspending beam 104. When the electric field force formed by the voltage between the first suspending beam 104 and the second suspending beam 106 thereafter is smaller than the deforming force threshold of the first suspending beam 104, the first suspending beam module 101 has an inherent pulling stress force to make the first suspending beam 104 rebound to the original state, thus, constituting an MEMS switch member.

In other words, when the electric field force of the voltage between the first suspending beam 104 and the second suspending beam 106 is smaller than a predetermined value, the first suspending beam module 101 is not electrically contacted with the conductive suspending beam module 102. When the electric field force achieves the predetermined value, the first suspending beam module 101 is electrically contacted with the conductive suspending beam module 102, so that the conductive suspending beam module 102 has a voltage same with the first suspending beam module 101.

Referring to FIG. 3A, FIG. 3A shows a top view of a driving member 100a in an original state in accordance with another embodiment of the present invention. A first suspending beam module 101a is arranged between a conductive suspending beam module 102a and a second suspending beam module 103a. In the original state, the first suspending beam 104a, the conductive suspending beam 105a and the second suspending beam 106a are all hung. In use, the first suspending beam 104a and the second suspending beam 106a can be provided with two homopolar voltages, due to an electric field repulsion force between the first suspending beam 104a and the second suspending beam 106a, the first suspending beam 104a moves to electrically contact with the conductive suspending beam 105a.

Referring to FIG. 3B, FIG. 3B shows a top view of the driving member 100a provided with homopolar voltages. When both the first suspending beam 104a and the second suspending beam 106a are provided with a same positive voltage V+ or a same negative voltage V−, due to the electric field repulsion force is larger than the deforming force threshold of the first suspending beam 104a, the first suspending beam 104a moves away from the second suspending beam 106a to electrically contact with the conductive suspending beam 105a, so that neighboring conductive suspending beam 105a and first suspending beam 104a are short circuited, and the neighboring conductive suspending beam 105a has a voltage same with the first suspending beam 104a. When the electric field force of the voltage between the first suspending beam 104a and the second suspending beam 106a is smaller than the deforming force threshold of the first suspending beam 104a, the first suspending beam module 101a has an inherent pulling stress force to make the first suspending beam 104a rebound to the original state, thus constituting an MEMS switch member.

FIG. 4 shows a matrix array module 300 formed by a plurality of the driving members 100 in the first embodiment, where each the driving member 100 corresponds to a pixel in a corresponding position on a liquid display panel (not shown). The matrix array module 300 is formed on a substrate. The substrate is made of a glass substrate or another transparent insulating substrate. The matrix array module 300 further includes a plurality of scanning line groups 302 and a plurality of signaling line groups 303. Each of the scanning line groups 302 includes a plurality of scanning lines respectively connected to the second suspending beam modules 103 of a plurality of driving members 100 in a same row. The neighboring driving members 100 are electronically connected through the substrate. Each of the signaling line groups 303 includes a plurality of signaling lines respectively connected to the first suspending beam modules 101 of a plurality of driving members 100 in a same column.

When a voltage is provided between the first suspending beam 104 and the second suspending beam 106 of the driving member 100, for example, the scanning line and signaling line connected to the driving member 100 are conducted, a voltage is formed between the first suspending beam 104 and the second suspending beam 106 of the driving member 100. Electrical signals are transmitted from the first suspending beam holding terminal 107 and the second suspending beam holding terminals 109 respectively to the first suspending beam 104 and the second suspending beam 106. Due to an electric field attractive force is larger than the deforming force threshold of the first suspending beam 104, the first suspending beam 104 moves towards the second suspending beam 106 to electrically contact with the conductive suspending beam 105, so that neighboring conductive suspending beam 105 and first suspending beam 104 are short circuited, and the neighboring conductive suspending beam 105 has a voltage same with the first suspending beam 104. When the voltage between the first suspending beam 104 and the second suspending beam 106 is 0V, or the electric field attractive force generated by the voltage is smaller than the deforming force threshold of the first suspending beam 104 (for example, it is designed that when the scanning line and the signaling line connected to the driving member 100 are not conducted, the scanning line and the signalling line have a same voltage or a voltage therebetween is smaller than a predetermined value), the electric field attractive force between the first suspending beam 104 and the second suspending beam 106 is decreased, thus the first suspending beam module 101 has an inherent pulling stress force to make the first suspending beam 104 rebound to the original state. Accordingly, the action of a pixel arranged in the corresponding position is controlled according to on and off states of the scanning line and the signal line connected to the driving member 100.

It should be understood that, the matrix array module 300 can also be formed by a plurality of the driving members 100a arranged in array instead. A function of the driving member 100a can be implemented with a repulsion force between the first suspending beam 104 and the second suspending beam 106.

The conductive transparent layer 503 is formed on the second insulating layer 404. The conductive transparent layer 503 can be made of one of tin doped indium oxide (ITO), indium zinc Oxide (IZO) and ZnO. After that, a sacrifice layer 405 is further formed on the conductive transparent layer 503. The sacrifice layer 405 can be made of molybdenum (Mo), polymer, and so on. Then, a contacting hole 4051 is defined in the sacrifice layer 405 and the conductive transparent layer 503, and a suspending beam pattern 406 is formed on the sacrifice layer 405.
