Problems solved by technology

In the liquid crystal display adopting 2G3D design, since all scanning lines 1 are only connected by two short-circuit bars 4, 5 (that is, connecting odd-numbered scanning lines and even-numbered scanning lines respectively), all odd-numbered scanning lines or even Row scan lines are controlled using the same timing (see figure 2 ), so that it is impossible to effectively detect defects caused by short circuits between two adjacent odd-numbered or even-numbered scanning lines (for example, due to scratches or line residual gold)

Embodiment Construction

[0033] The present invention relates to a liquid crystal display assembly with a better short-circuit bar design, which is mainly composed of a first substrate, a second substrate and liquid crystal filled between the two substrates. The substrate can be a glass substrate, a flexible substrate or an opaque substrate. The first substrate is provided with a plurality of matrix-arranged pixel (pixel) areas, which are provided with switching elements (switching element) (such as thin film transistors (TFT)) and pixel electrodes; The color filter and the common electrode (common electrode). Generally, the first substrate is called a thin film transistor substrate, and the second substrate is called a color filter substrate because it is provided with color filters. A spacer (spacer) (not shown in the figure) is generally provided between the two substrates to define the gap between the two substrates, and the surfaces of the two substrates are respectively attached with polarizers...

Abstract

Wherein, the LED unit comprises: multiple scanning lines and intersected data lines to form multiple pixel zones on substrate, at least one shorting bar with a first / second sub-odd scanning lines electric connected to the (m+1)th / (n+3)th scanning lines respectively, and one shorting bar with even scanning lines with a first / second sub-even scanning lines electric connected to the (o+2)th / (p+3)th scanning lines respectively (wherein, m, n, o, p = 0, 4, 8, 12,...).

Description

technical field [0001] The present invention relates to a liquid crystal display device, and in particular to a shorting bar structure with a 4G3D design. Background technique [0002] A liquid crystal display assembly generally consists of a first substrate, a second substrate and liquid crystal filled between the two substrates. The first figure shows a partial top view of a first substrate of a known liquid crystal display assembly. Generally speaking, a group of scan lines 1 and a group of data lines 2 are disposed on the first substrate. Two adjacent scan lines 1 and two adjacent data lines 2 define a pixel area. Each pixel area is provided with a thin-film transistor 3 (thin-film transistor, TFT) and a pixel electrode (not shown in the figure). The second substrate (not shown in the figure) is generally provided with a color filter for displaying colors and a common electrode. [0003] During the liquid crystal display manufacturing process, the aforementioned scan...
