Problems solved by technology

[0004] However, due to the resistance-capacitance (RC) load on the common electrode, the left and right adjacent pixels will be unbalanced when charging and discharging, so the double-gate display will cause vertical stripes defects when displaying.

Embodiment Construction

[0032] Figure 1A A double / dual gate liquid crystal display (LCD) 100 is shown, which includes pixel electrodes 10 arranged in a matrix of rows and columns. Figure 1B show Figure 1A Part of the detailed circuit diagram. In each pixel unit (or pixel for short), each pixel electrode 10 corresponds to a switching element (such as a thin film transistor (TFT)) 12 . Adjacent thin film transistors (such as 12A and 12B) in the same column are commonly connected to the same source line (such as S1), which is driven by the source driver 14; The sources are connected together by a shared source line (S1). Part of the thin film transistors 12 in the same row (for example, the odd order thin film transistors in the first row) are connected together through a gate line (for example, G1) and driven by the gate driver A (16); while the other part of the row The thin film transistors 12 (for example, even order thin film transistors in the first row) are connected together through another...

Abstract

The invention discloses a driving mechanism of a multiple-fold gate LCD (such as a double-fold gate LCD). Several lines of pixel electrode groups A and groups B are driven in a forward driving sequence; then, adjacent lines of pixel electrode groups A and groups B are driven in a backward driving sequence.

Description

technical field [0001] The invention relates to a liquid crystal display (LCD), especially a driving mechanism of a double gate liquid crystal display, so as to effectively reduce vertical line defects. Background technique [0002] A liquid crystal display (LCD) is generally composed of pixel units (or pixels for short) arranged in a matrix of rows and columns. Each pixel includes a thin film transistor (TFT) and a pixel electrode, which are jointly formed on a substrate (or panel). The gates of the thin film transistors in the same row are connected together through a gate line, and then controlled by a gate (or scanning) driver. The sources of the thin film transistors in the same row are connected together through a source line, and then controlled by a source (or data) driver. A common electrode is formed on another substrate (or panel). A liquid crystal (liquid crystal, LC) is sealed between the pixel electrode substrate and the common electrode substrate, and each ...
