Within one pixel element 200, two display circuits corresponding to the analog display mode and the digital display mode are disposed such that they are adjacent to each other. One of these two display circuits can be selected through the circuit selection circuits 40 or 43. Since the high voltage power line 150 of the retaining circuit 110, which is used under the digital display mode, also performs as the signal selection line 88, it is possible to have the high density integration of the pixel element 200. Also, the bias voltage Vsc supplied through the selection storage capacitor line 81 is same as the signal A. Therefore, the storage capacitor line 81 is connected to the drain of the TFT 122 of the signal selection circuit 120 so that the signal line 82 for supplying the signal A can be omitted. Thus, the high-density integration of the pixel element 200 can be achieved.

A method and apparatus are described for a User Equipment (UE) to transmit in a control channel ACKnowledgement signals associated with a Hybrid Automatic Repeat reQuest process (HARQ-ACK signals) in response to receiving Transport Blocks (TBs) transmitted from a base station. The UE conveys the HARQ-ACK information by selecting one resource from multiple resources in the control channel and by selecting a constellation point of the modulation scheme for the HARQ-ACK signal. Transmission diversity is supported using different control channel resources that are already available to the UE without configuring additional resources. Design principles are described to optimally map the HARQ-ACK information to control channel resources and modulation constellation points for a Time Division Duplex (TDD) system and for a Frequency Division Duplex (FDD) system.
