Liquid crystal panel, manufacturing method thereof, and display device

Abstract

The invention discloses a liquid crystal panel. The liquid crystal panel comprises a color film substrate, an array substrate, liquid crystal between the color film substrate and the array substrate, a photo spacer on the color film substrate, a crystal covering thin film and a circuit board, wherein a conversion terminal set which is led from a signal wire is arranged on the surface of the array substrate, a conducting electrode is arranged on the end surface of the photo spacer, and the photo space abuts one end of the conducting electrode against the conversion terminal set; the other end of the conducting electrode is arranged on a non-display area of the liquid crystal panel and is bound with the crystal covering thin film, and the circuit board is arranged on the side where the array substrate locates. The invention further discloses a manufacturing method of the liquid crystal panel and a display device. The conversion terminal set is formed and led from the signal wire on the surface of the array substrate, the photo spacer is manufactured on the color film substrate side, the photo spacer presses the conducting electrode onto the conversion terminal set, and the conversion terminal set and the crystal covering thin film are bound, accordingly the situation is avoided that the array substrate side extends out of a long binding zone, and the manufacturing method is beneficial for achievement of a super-narrow frame or no frame.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a liquid crystal panel, a manufacturing method thereof, and a display device. Background technique [0002] Chip On Film (COF), that is, the chip (IC) is fixed on the soft film of the flexible circuit board (FPC). This packaging technology is used in many display panels such as LCD and OLED. Chip. This chip is mostly used as a source driver and a gate driver for display drivers. In the driving circuit, one end of the COF is connected to the printed circuit board (PCB), which is responsible for receiving the data signal transmitted from the printed circuit board, and the other end of the COF is connected to the display panel (Panel), which is used to transmit the data signal output by the IC to On the display panel, to drive the display panel for display. [0003] Specifically, the connection between the COF and the printed circuit board and the display panel i...

Problems solved by technology

There is even a "frameless" panel concept, that is, to remove the outer frame that blocks the non-display area of ​​the panel to achieve a borderless display. However, since the bonding end on the TFT substrate side is longer than the CF substrate, a special outer frame needs to be reserved to cover the panel. The connection lines in the binding area affect the narrow border, and the borderless display cannot be realized
