Problems solved by technology

[0004] However, with the development of thinner and thinner screens and higher screen-to-body ratios, the requirements for narrow borders of LCD panels continue to increase. The black matrix on the edge of the color filter substrate needs to be cut evenly, resulting in the accumulation of static electricity in the black matrix layer during ESD testing, which affects the liquid crystal layer. Distorted, resulting in poor display such as purple or green

Embodiment 1

[0026] An embodiment of the present invention provides a color filter substrate, such as figure 2 As shown, the color filter substrate includes: a substrate 10 and a black matrix 12 arranged on the substrate 10, at least one conductive protrusion 14 is arranged on the black matrix 12 in the non-display area around the color filter substrate 1, and the top of the conductive protrusion 14 is used for It abuts against the GND line 21 of the array substrate 2 .

[0027] The conductive protrusion 14 is arranged in the non-display area around the color filter substrate 1, and is made of conductive material or coated with a conductive material on the surface, and its bottom end is arranged on the black matrix 12 in the non-display area, and is electrically connected with the black matrix 12 , the top of which abuts against the GND line 21 of the array substrate 2 . The height of the conductive protrusion 14 is consistent with that of the spacer, that is, the thickness of the liquid...

Embodiment 2

[0034] On the other hand, an embodiment of the present invention also provides a display panel, including: a color filter substrate and an array substrate, at least one conductive protrusion is arranged on the black matrix in the non-display area around the color filter substrate, and the array substrate A GND wiring is provided, and the top of the conductive protrusion abuts against the GND wiring of the array substrate.

[0035] In this embodiment, special conductive bumps are set on the color filter substrate. The conductive bumps can conduct electricity and are designed in the shape of spacers (PS). They are connected to the black matrix layer on the color filter substrate and correspond to the conductive bumps on the array substrate. Set the GND line at the raised position. When the color filter substrate and the array substrate are boxed, the black matrix is ​​connected to the GND line of the array substrate through the conductive bumps to guide away the static electricit...

Abstract

The invention discloses a colored film substrate, a display panel and a display device and relates to the field of displaying, solving the problems of poor displaying such as purpling and greening, which are caused by a factor that static electricity is accumulated on a black matrix layer. The colored film substrate provided by the invention comprises a substrate and a black matrix arranged on the substrate, wherein at least one conductive bulge is arranged on the black matrix in a non-displaying region at the periphery of the colored film substrate; the top end of the conductive bulge is pressed against the GND route of the array substrate.

Description

technical field [0001] The invention relates to the display field, in particular to a color filter substrate, a display panel and a display device. Background technique [0002] Liquid Crystal Display (Thin Film Transistor Liquid Crystal Display, referred to as TFT-LCD) has the characteristics of small size, low power consumption, no radiation, etc., and occupies a dominant position in the current flat panel display market. [0003] The LCD panel is the main part of the LCD display, such as figure 1 As shown, it mainly includes a color filter substrate 1 and an array substrate 2 arranged in pairs, and a liquid crystal layer (not shown in the figure) filled between the color filter substrate 1 and the array substrate 2. The substrate 10 of the color filter substrate 1 A layer of transparent conductive layer (Back ITO) 11 is sputtered on the upper surface of the array substrate 2, connected to the ground trace (GND trace) 21 on the array substrate 2 with silver glue, and the ...
