Problems solved by technology

[0006] However, the first known technology still has the problem of light leakage. When the light absorption value or optical density (Optical Density, OD) of the color filter layer 221 is insufficient, the light will still be emitted through the color filter layer 221, so that the light-shielding area Z2 is generated. light leak
[0007] In addition, the second known technology is easy to form an electrostatic discharge structure with the metal wire layer 222, that is, the so-called capacitive structure. Therefore, it is easy to cause damage to parts due to the electrostatic discharge effect, resulting in an open circuit (OpenCircuit, OC) of the signal line. Occurrence, and the physical phenomenon of large capacitance caused by the distance between the metal layers is too close, increasing the resistance / capacitance load problem, causing delay and damage to the signal waveform transmission

[0060] Please refer to Figure 2A and Figure 2B As shown, the liquid crystal display device 30 according to the first embodiment of the present invention includes a backlight module 100 and a liquid crystal display panel 300 . The backlight module 100 is, for example, a Direct Type backlight module or a Side-Edge Type backlight module. In this embodiment, the backlight module 100 is illustrated by taking the direct type backlight module as an example, but it is not intended to limit the scope of rights of the present invention.

[0061] The liquid crystal display panel 300 is, for example, an in-plane switching (IPS) type liquid crystal display panel, a multi-domain vertical alignment (MVA) type liquid crystal display panel, a twisted nematic (TN) type liquid crystal display panel, a color filter and a thin film transistor array ( COA) liquid crystal display panel or transflective liquid crystal display panel. In this embodiment, a COA type liquid crystal display panel wil...

[0085] The second embodiment of the present invention, such as Figure 8The difference between the liquid crystal display panel 500 of the shown liquid crystal display device 50 and the liquid crystal display panel 300 of the first embodiment is that the first substrate 510 and the second substrate 520 are, for example, a combination of a color filter substrate and a thin film transistor substrate. This will be described by taking the combination of the first substrate 510 being a thin film transistor substrate and the second substrate 520 being a color filter substrate as an example.

[0086] Same as the first embodiment, the second substrate 520 has a first light-shielding layer 521 and a second light-shielding layer 522 on it. The first light shielding layer 521 is, for example, a color filter layer or an organic insulating layer, and the second light shielding layer 522 is, for example, a second electrode layer or a metal layer.

[0087] Therefore, similarly, the first li...

The invention also discloses a driving method that corresponds to the device.

Description

technical field [0001] The invention relates to a method for reducing light leakage in a light-shielding area, in particular to a method for reducing light leakage in a light-shielding area used in a liquid crystal display device and a liquid crystal display panel. Background technique [0002] With the gradual maturity of liquid crystal display (Liquid Crystal Display, LCD) technology, it has gradually replaced the traditional display technology using cathode ray tube (Cathode Ray Tube, CRT), and is widely used in various electronic products. Among them, liquid crystal display panels can be divided into in-plane switching (InPlane Switching, IPS) type, multi-domain vertical alignment (Multi-domain Vertical Alignment, MVA) type, twisted nematic (TwistNematic, TN) type, color filter and thin film transistor array (ColorfilterOnArray, COA) type or semi-transflective type (Transflective), etc. Herein, a COA type liquid crystal display panel will be used as an example for illus...
