Problems solved by technology

However, since the charging state of the M second wirings at this time is different from the charging state of the M second wirings after the second horizontal scanning period, the display state of the image display part in the first horizontal scanning period and There is a large difference between the display states of the image display section in the second horizontal scanning period, and the display image quality of the flat panel display device deteriorates

Embodiment 1

[0106] Embodiment 1 relates to a driving method of a flat panel display device according to a first embodiment of the present invention. As the flat panel display device of Embodiment 1 or Embodiment 2 to be described below, a flat panel display device equipped with electron emission elements, specifically, a cold cathode electric field electron emission display device (hereinafter simply referred to as a display device) is used as the assembly. A flat panel display device having cold cathode electric field electron emission elements.

[0107] Such as Figure 1A As shown in the conceptual view, the display device of Embodiment 1 or Embodiment 2 to be described below has:

[0108] (A) The first wiring group 113 (113 1 , 113 2 ), the first wiring group is composed of N first wirings (specifically, gate electrodes 13 to be described below) extending in a first direction (specifically, for example, a horizontal direction).

[0109] (B) The second wiring group 111 (111 1 , 111...

Embodiment 2

[0127] Embodiment 2 relates to a driving method of a flat panel display device according to a second embodiment of the present invention. The flat panel display device in Example 2 has substantially the same configuration and structure as that in Example 1.

[0128] In Embodiment 2, the first wirings are driven by a line-sequential driving system, wherein the first to Nth first wirings (gate electrodes 13 ) are sequentially selected. The Nth first wiring is selected, and subsequently, the 1st first wiring is selected. After the selection of the Nth first wiring (gate electrode 13) until the selection of the first first wiring (gate electrode 13), apply predetermined voltage. That is, the (1, Nth 1 After the completion of ) horizontal scanning periods and before the start of the first horizontal scanning period in the next specific frame, in other words, during a period corresponding to what is called a vertical blanking period (vertical blanking period), the predetermined v...

Abstract

A driving method of a flat panel display apparatus of a line-sequential driving system in which the display apparatus has N first wirings extending in a first direction, M second wirings extending in a second direction different from the first direction, and image display portions formed in overlapped regions of the first wirings and the second wirings, and the first to Nth first wirings are sequentially selected. A predetermined voltage is applied to each of the M second wirings for a period of time until the first first wiring is selected after the Nth first wiring was selected.
