Abstract

The invention discloses a two-dimensional display and a chip joint sheet thereof. The two-dimensional display comprises a display panel, a flexible circuit board, a first source drive chip, a second source drive chip and a control circuit board. A plurality of first lead wires and second lead wires are arranged in the peripherical circuit area of a display panel, are respectively extended from the lower part of the flexible circuit board to two opposite sides of the display panel and are electrically connected with the flexible circuit board. The first source drive chip is electrically connected with the flexible circuit board through a part of electric property of the first lead wires. The second source drive chip is connected electrically connected with the flexible circuit board through the second lead wires. The chip joint sheet is positioned under the first source drive chip or the second source drive chip; a first dielectric layer of the joint sheet is provided with a plurality of first contact openings; a second dielectric layer is provided with a plurality of second contact openings and third contact openings which are alternately arranged; and the second contact openings are corresponding to the first contact openings.

Description

technical field [0001] The invention relates to a flat display and a chip bonding pad, and in particular to a flat display with signal transmission impedances matched to each other and a chip bonding pad with low signal transmission impedance. Background technique [0002] With the development of the information industry, the requirements for the volume occupied by various displays in the market are getting higher and higher, and therefore various displays are constantly developing towards thinning. For example, flat panel displays such as liquid crystal displays and organic light emitting displays have replaced traditional picture tube displays and become mainstream products of displays. [0003] Figure 1A It is a schematic diagram of a traditional flat panel display. Please refer to Figure 1A , the flat panel display 100 includes a display panel 110 , a plurality of flexible circuit boards 120 , a plurality of driving chips 130 and a control circuit board 140 . The dis...
