Description of the invention (14) 'When the notebook computer is used in a portable manner, it can be used for a longer time. In addition, with the higher resolution of the liquid crystal display panel, even if the frequency f of the display data or the display control signal becomes high, or the full capacity C of the signal line increases, the power consumption of the display control device 110 can be reduced to Equal to the level of knowledge. Thereby, the heat generation of the display control device 110 can be the same as that of the conventional example. Therefore, as a package of a semiconductor integrated circuit (LSI) constituting the display control device 110, a package without additional heat dissipation means, Or a package with good heat dissipation, you can use a low-cost resin model package. The interface substrate 100 on which the display control device 110 is mounted is provided along one side of the liquid crystal display panel. Therefore, when the amount of heat generated by the display control device 110 is greater than the amount of heat released, its heat is transferred to the liquid crystal display panel 10, and the position of the liquid crystal display panel 10 causes a difference in the temperature of the liquid crystal layer, which is generated in the display. Uneven. However, according to this embodiment, since the heat generation of the display control device 110 can be suppressed, the display on the liquid crystal display panel 10 does not cause unevenness. Similarly, with the multi-tone display of the liquid crystal display panel, even if the root of the display data is increased, the power consumption of the display control device 110 can be reduced. In particular, the frequency f of the signal supplied to the display data bus line 1 3 3 and the display data latch clock line 1 3 1 is extremely high as shown in (5). --------------------- Γ Order -------- Line · (Please read the notes on the back before filling this page) This paper size is applicable China National Standard (CNS) A4 specification (210 X 297 public love) -17- 529007 A7 B7 5 V. Description of the invention (15 f = (one line of pixels X 3) / horizontal scanning cycle so 'make display data bus line The signal amplitude of 1 3 3 and the display data 卩 jg lock, clock line 1 3 1 is lower than the ig number amplitude of the display control device 1 1 〇's body control section 1 1 1 ', which can greatly reduce the power consumption of the liquid crystal display device. Also, even if a power supply potential of 2.5 V is supplied as the power supply potential of the main control section 1 1 1 and the output buffer section 1 12, the same effect as that of this embodiment can be obtained. When the power supply potential is supplied to the main body control section 1 1 1 and the output buffer section 1 12, the display data or the delay time of the display control signal changes, so the circuit design of the display control device 1 10 must be restarted. In accordance with this, a photomask or the like for manufacturing a semiconductor integrated circuit (LS I) constituting the display control device 110 must be made. It is new, so it has the disadvantage of high price. However, in this embodiment, it is only necessary to supply a power potential of 2 · 5 V to the output buffer section of the output section of the display control device 110, so there is no need to The circuit design of the display control device 110 is greatly changed, so that the cost of i can be avoided. In addition, the power supply potential of each driver 230 can also be matched with the display data of each signal line or the amplitude of the control signal. (2 · 5 V). However, when the power supply voltage of the signal output section 2 31 of each driver 2 30 is decreased, the delay time of the signal in the signal output section 2 31 may be changed, or the liquid crystal display may be driven.

The signal delay within the signal output section 2 31 can be reduced, and a sufficient driving voltage can be given to the drain signal line D or the gate signal line G. Furthermore, in this embodiment, since the amplitude of the display data or the display control signal on each signal line is 2.5 V, the characteristics of EMI (electromagnetic interference) can be improved. That is, in this embodiment, independently of the signal amplitude of the body control section 1 11 of the display control device 1 1 0, the amplitude of the signal output from the display control device 1 1 0 to each signal line can be reduced. Signal lines do not emit unwanted electromagnetic waves. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. In particular, the liquid crystal display device must have a driving circuit around the liquid crystal display panel 10, so each signal line connected to the display control device 110 is along the liquid crystal display panel. One side of 1.0 becomes a very long and straight wiring. That is, each signal line functions as an antenna for a high-frequency signal system, so that electromagnetic waves are easily radiated. Therefore, the liquid crystal display device is provided with a shielding means such as a shielding box to suppress unnecessary electromagnetic waves; i. However, as in this embodiment, the amplitude of the signal applied to each signal line is made smaller than the signal amplitude of the logic circuit in the display control device 110 or each driver 230, so that the electromagnetic wave from each signal line Radiation becomes difficult, and a simple structure can improve the EMI characteristics of the liquid crystal display device.

The signal amplitude of the line 1 3 1 of the latch clock (CL 2) is smaller than the signal amplitude of the logic circuit in the display control device 1 10 or each driver 2 3 0.
