Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a display device in which a large number of signals - electric palpitations are assembled in a matrix. 1 method of driving a signal-absent electrode without any problems. By assembling the signal voltage #A into a matrix and emitting gas such as plasma at the intersection, it is possible to respond to the signal applied to the electrode. The display h-, which can display characters and symbols, is known in principle. In order to select the vertical and horizontal 512 lines of the electric conductor and select the i-trix K111 vertical and cross points to discharge, the address movement waveform is applied to a specific electrode among the electrodes in each direction, and the address movement waveform is applied once. He started discharging,
In order to maintain the discharge, a sustain drive path that constantly applies a drive waveform to all the electrodes at once is required, and conventionally, a configuration in which the drive path is completely separate has been adopted. As a result, the power of the elements used increases, resulting in high costs and decreased reliability. Historically, the KlIA dynamic circuit itself generates a wide variety of voltages. The voltage of the TI electrode shown in FIG. Also, please make sure that the 1114Y11 pole is not connected to the holding voltage marker and the writing voltage marker 1. The voltage between the 2nd inverter and the 9m2 is required; The dynamic voltage DBY has a T waveform.

The purpose of the X invention is to improve the above-mentioned drawbacks and make the driving voltage waveform 1: Change! 1! Signal axis electrode &? 7. To provide a method. Therefore, the gist of the present invention is to set the first intermediate voltage to the ground potential,
The voltage between the second inverter and the sustaining voltage K) is added by 1%.

The following is a detailed explanation of the implementation of the invention in the drawings. Figure 3 shows a drive circuit with one xl electrode (81 poles) (/J configuration W, Figure and S shows a drive circuit with 512 I electrodes).

Therefore, the number of electrodes may be extremely small compared to the number of electrodes. Compared to conventional operations such as erasing using an intermediate voltage V, the applied voltage is different, and the electrical energy at the electrode alternating point AK is Jl!

There is a necessity. Note that Kffl is used for the simultaneous erasure of No. 4181 in order to erase only 11 characters/figures 11 consisting of 16 points in l block.

In this way, according to the present invention, the voltage waveform 1i11ilIl for starting, maintaining, and erasing the discharge is reduced to rx<t,
Therefore, the operation of the zero display device is different from the conventional one (the number of driving circuits can be greatly reduced)
