Gate driver, electro-optical device, electronic instrument, and drive method

Abstract

A gate driver includes a first gate output circuit which outputs a select signal for selecting the first gate line, a second gate output circuit which outputs a select signal for selecting the second gate line in a select period subsequent to the select period of the first gate line, and a transistor as a first gate line short-circuiting circuit provided between outputs of the first and second gate output circuits. The transistor short-circuits the outputs of the first and second gate output circuits in a period between the select period of the first gate line and the select period of the second gate line.

Description

technical field [0001] The invention relates to a gate driver, an optoelectronic device, an electronic device, a driving method and the like. Background technique [0002] In recent years, as a liquid crystal display (Liquid Crystal Display: LCD) panel (a display panel in a broad sense; an optoelectronic device in a broader sense) mounted on electronic equipment such as a mobile phone, there are known simple matrix LCD panels and the use of An active-matrix LCD panel using switching elements such as thin film transistors (Thin Film Transistor: hereinafter referred to as TFT). [0003] The simple matrix method is easier to achieve lower power consumption than the active matrix method, but it is difficult to realize multi-color and moving image display. On the other hand, the active matrix method is suitable for multi-color and moving image display, but it is difficult to achieve low power consumption. [0004] A simple matrix type LCD panel or an active matrix type LCD pane...

Problems solved by technology

[0008] However, the technique disclosed in Patent Document 1 has a problem that the reduction effect of power consumption depends on the voltage given on the source line.

Therefore, there are cases where the reduction effect of the amount of electric charge that charges and discharges the counter electrode whose polarity is reversed is less than ideal

In addition, in the technique disclosed in Patent Document 1, there is a problem in that the two electrodes interposing the liquid crystal are short-circuited depending on the relationship between the voltage given on the source line and the polari
