Problems solved by technology

Moreover, in order to prevent light leakage caused by the deviation of the two glass (array substrate and color filter substrate) of the liquid crystal display panel due to process errors or external forces, the black matrix is ​​designed to cover and exceed a certain distance from the data lines and scanning lines. , which will inevitably sacrifice the light-transmitting area of ​​the pixel unit, that is, the aperture ratio of the pixel unit will decrease, which will indirectly lead to an increase in the energy consumption of the entire display panel.

Embodiment Construction

[0033] The pixel unit of the liquid crystal display panel proposed by the present invention is covered with a layer of shielding electrode on the electrically connected data lines and scanning lines, as well as other conductors that may have different potentials from the pixel electrodes, to shield the data lines and scanning lines. line, and the electric force line of the conductor to the common electrode, thereby reducing light leakage. In addition, because the shielding electrode is provided, the black matrix can be reduced or even completely discarded. In this way, while reducing light leakage, the aperture ratio of the pixel unit is also increased, and the energy consumption of the entire display device is reduced.

[0034] Such as figure 2 with image 3 Specifically, in the above-mentioned pixel unit of the liquid crystal display panel, the shielding electrode may be electrically connected to the common electrode to have the potential of the common electrode, or electr...

Abstract

The invention relates to a liquid crystal display panel which comprises an array substrate. The array substrate comprises a substrate, a plurality of common electrode wires, a plurality of scan lines, a plurality of data lines and a plurality of pixel units; the common electrode wires are configured on the substrate; the scan lines and the data lines are configured on the substrate in a staggered manner so as to form a plurality of pixel areas; each pixel unit is configured in the corresponding pixel area and comprises a pixel electrode and a switch element, the switch elements are electrically connected with the scan lines, the data lines and the pixel electrodes and are used for being switched on under the effects of voltage signals of the scan lines, so that voltage signals on the data lines can be transmitted to the pixel electrodes, and the pixel electrodes have corresponding electric potential; corresponding shielding electrodes cover the upper sides of the corresponding scan lines and the corresponding data lines in each pixel area and are electrically connected with the corresponding pixel electrodes or the corresponding common electrode wires. The liquid crystal display panel has the advantages that light leak phenomena can be reduced, and the liquid crystal display panel is high in pixel unit aperture ratio.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel with reduced light leakage. Background technique [0002] Active liquid crystal display panel (TFT LCD) has become a mainstream product in the market due to its excellent performance. An active liquid crystal display panel usually consists of an array substrate, a color filter substrate and a liquid crystal layer. Wherein, a plurality of scan lines (Scan Line) and data lines (Data Line) are alternately arranged on the array substrate to form a plurality of pixel areas, each pixel area is configured with a pixel unit (Pixel), and each pixel unit includes at least one A thin film transistor (TFT), and a pixel electrode (Pixel Electrode) correspondingly connected to the thin film transistor. The thin film transistor is used as a switching element to start the operation of the pixel unit, and is connected to the scanning line and the da...
