摘要： PROBLEM TO BE SOLVED: To obtain the display device, in which an EMI countermeasure is accomplished, the number of parts is reduced and an automatic assembly is made suitable, by fixing a spring element to a display panel or a stage and connecting the frame ground of a bezel and the signal ground of the device. SOLUTION: A spring element 32 is fixed to a flexible printed circuit board 30 on a display panel 12. The board 30 includes a signal ground(SG) and the element 32 is soldered to the SG. If the panel 12 is covered by a bezel 10, the eliminated part of the insulation cover of the inner surface of a display plate section 16 of the bezel 10 contacts to the spring element 32 on the panel 12. Thus, the signal element 32 electrically connects the frame ground of the bezel 10 to the signal ground of the board 30. Furthermore, the element 32 has a sufficient elasticity in the compressing direction and prevents the vibration of the panel 12.

摘要： PURPOSE:To protect retention data by writing the data from an external part and the storing data of a second storing area, which is provided to a magnetic bubble memory, to a first storing area with a logical operating means and outputting them to the external part with executing reverse conversion when these data are read. CONSTITUTION:At the writing time of the data, the data stored to a second storing area 32 of a magnetic bubble memory 3 (the special data of a pass-word, etc.,) and the external data to be inputted to a control means 1 are operated by a logical operating means 2 and the operated result is stored to a first storing area 31 of the magnetic bubble memory 3. On the other hand, at the reading time of the data, the data of this first storing area 31 and the data of the second storing area 32 are operated and the reverse conversion is executed so that these data can be the same data as the external data inputted to the control means 1 at the writing time. Then, these data are outputted to a data bus. Thus, since the exact reading of the data can not be executed by a device not to equip the same logical operating means, information stored to the magnetic bubble memory can be protected.

摘要： PROBLEM TO BE SOLVED: To provide the driving method for a liquid crystal display device capable of writing a multilevel signal on a display electrode sufficiently even when bluntness is generated in a gate signal and to provide a liquid crystal display device using the same method. SOLUTION: In the state shown in the figure 1 (a), a gate delay is not generated in a gate signal Gn and the gate signal Gn has a pure rectangle shape. In the state shown in the 1 (b), the gate delay is generated in the signal and a gate signal Bf on a gate bus line 2 is blunted. However, a data signal Df is not outputted at the same timing as that of a data signal Dn and the changeover timing of the data signal Df is delayed by Δt than that of the data signal Dn. As a result, even though a gate-off time is delayed by an amount equivalent to the bluntness of the gate signal Gf, since the changeover time of the data signal of the data signal Df is also delayed by Δt, the original level of the data signal Df can be correctly written on a pixel electrode 8.
