Definitions
- the present invention in the above structure, there is provided a semiconductor device, wherein the first transistor and the second transistor have the same conductivity type.
- the current source transistor 101 and the wiring 112 are connected to the basic current source 108 via the switch 106. In parallel with this, the current source transistor 101 and the wiring 113 are connected via a load 109 and a switch 107. Note that the wiring 110 and the wiring 111 are configured as separate wirings, but may be electrically connected. Note that the wiring 112 and the wiring 113 are formed of different wirings, but may be electrically connected.
- the load 109 is an EL element
- writing can be performed using a current lb larger than the current flowing through the EL element. Therefore, troubles such as the signal current being buried in the noise can be avoided, and a quick write operation can be performed.
- the potential of the gate terminal of the current source transistor 101 hardly changes between the case of the short-circuit operation (setting operation) and the case of the current source operation (output operation).
- FIG. 1 shows an example in which a second switching transistor 1201 and a switch 1202 are provided. Note that the current source transistor 101 and the switching transistor 102 are both P-channel types in FIG. 1, but are not limited thereto.
- FIG. 13 shows an example of the circuit of FIG. 1 in which the polarity (conductivity type) of the current source transistor 101 and the switching transistor 102 is changed and the circuit connection structure is not changed. As can be seen by comparing FIGS. 1 and 13, the potentials of the wirings 112, 113, 110, and 111 in FIG.
- the current source transistor 1401 that always operates as a current source (or a part of it), and a switching transistor 1402 that operates differently depending on the state.
- the current source transistor 1401, the switching transistor 1402, and the wiring 110 are connected in series. Have been.
- One terminal of a capacitor 1404 is connected to the gate terminal of the current source transistor 1401.
- the other terminal 1406 of the capacitor 1404 is connected to the source terminal of the switching transistor 1402 (current source transistor 1401). Therefore, the gate-source voltage of the current source transistor 1401 can be held.
- the gate terminal and the drain terminal of the current source transistor 1401 are connected via a switch 1405, and the charge holding of the capacitor 1404 can be controlled by turning on and off the switch 1405.
- the switch may be placed anywhere. That is, of course.
- FIG. 14 shows the circuit corresponding to FIG. 1, but FIG. 23 shows the circuit corresponding to FIG. FIG. 23 has a feature that no charge is accumulated in the gate capacitance of the switching transistor 1402 during the short-circuit operation.
- the switch 103 was turned off, and the current source transistor 101 and the switching transistor 102 operated as multi-gate transistors because the gate terminals were connected to each other.
- the gate terminals of the current source transistor 101 and the switching transistor 102 are not connected to each other, so that the switch 2602 is used to make the connection. As a result, it can operate as a multi-gate transistor.
- the switches 2601, 105, and 106 are turned off, and the switches 107 and 2602 are turned on.
- the path of the current at that time is indicated by a dashed arrow 2801.
- the gate terminal of the switching transistor 102 and the gate terminal of the current source transistor 101 are connected to each other.
- the charge accumulated in the setting operation is stored in the capacitor 104, and this is added to the gate terminals of the current source transistor 101 and the switching transistor 102.
- the current source transistor 101 and the switching transistor 102 operate as a multi-gate transistor. Therefore, when the current source transistor 101 and the switching transistor 102 are considered as one transistor, the gate length L of the transistors becomes larger than that of the current source transistor 101.
- the current flowing toward the load 109 is smaller than lb.
- the above operation corresponds to the output operation.
- the switching transistor 102 performs the current source operation.
- the potential of the wiring 2603 is not limited to Vss. Any value may be used as long as the switching transistor 102 is sufficiently turned on.
- FIG. 33 shows an example in which the polarity (conductivity type) of the current source transistor 101 and the switching transistor 102 is changed in the circuit of FIG. 26 by changing the circuit connection structure without changing the current direction. Shown in
- connection is made as shown in FIG. 34 during the setting operation, and the connection is made as shown in FIG. 35 during the output operation. So, if so, the switch can be placed anywhere.
- Vdd 2 higher than Vdd is supplied to the wiring 3303.
- the switch is used.
- the multi-transistor 3601 operates as a switch in an off state.
- switches such as 103, 105, and 106 can be placed anywhere as long as the target current can be controlled on and off. In other words, if the connection is made as shown in Fig. 39 during the setting operation and the connection is made as shown in Fig. 40 during the output operation, the switches like 103, 105, 106 etc. It can be placed anywhere.
- the display device includes a pixel array 4101, a gate line driving circuit 4102, and a signal line driving circuit 4110.
- the gate line driving circuit 4102 sequentially outputs a selection signal to the pixel array 4101.
- the signal line driver circuit 4110 sequentially outputs a video signal to the pixel array 4101.
- the pixel array 4101 displays an image by controlling the state of light according to a video signal.
- a video signal input from the signal line driver circuit 4110 to the pixel array 4101 is a current. That is, the state of the display element or the element that controls the display element arranged in each pixel changes according to the video signal (current) input from the signal line driver circuit 4110.
- Examples of display elements arranged in pixels include EL elements and elements used in FED (field emission display).
- the present invention may be applied to the reference current source circuit 4114 shown in FIGS. That is, the reference current source circuit 4114 corresponds to the load 1309 in FIG. 43, and another current source corresponds to the basic current source 1308 in FIG. Then you can think of it.
- Fig. 52 (H) shows a mobile phone, which has a main unit 13701, a housing 13702, a display 1370, an audio input 1370, and an audio output 1370. 5. Includes operation keys 13 07 06, external connection port 13 07 07, antenna 13 07 08, etc.

Note that the display section 133703 can suppress the current consumption of the mobile phone by displaying white characters on a black background. According to the present invention, the mobile phone shown in FIG. 52 (H) is completed.
