Problems solved by technology
Since only one COF 30 is connected between the printed circuit board 20 and the array substrate 10, and the lines of the COF 30 are dense, and its line width is only 20 to 30 microns, so when the COF 30 bears the gravity of the printed circuit board 20, it is easy to cause the lines in the COF 30 Damage, greatly reducing the pass rate of LCD screens designed with three-dimensional transistors

A liquid crystal screen and a liquid crystal display designed on the basis of a three-dimensional transistor. The liquid crystal screen comprises an array substrate (1), a printed circuit board (2), a first chip on film (3) fixedly provided with an integrated circuit (4), and at least one connecting piece (5) connected between the array substrate (1) and the printed circuit board (2), wherein the first chip on film (3) is attached between the array substrate (1) and the printed circuit board (2). The connecting piece (5) is arranged between the array substrate (1) and the printed circuit board (2), to support the array substrate (1) and the printed circuit board (2) to some extent, and share a part of the gravity of the printed circuit board (2) for the first chip on film (3) attached between the array substrate (1) and the printed circuit board (2), thereby avoiding damages to the circuit in the first chip on film (3), and further improving the qualified rate of the liquid crystal screen designed on the basis of the three-dimensional transistor.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal screen and a liquid crystal display based on a three-dimensional transistor design. Background technique [0002] The liquid crystal screen based on the three-dimensional transistor design in the prior art refers to a liquid crystal screen in which the gate circuit design is increased and the source circuit design is correspondingly reduced. refer to figure 1 , figure 1 It is a schematic diagram of a liquid crystal screen designed based on a three-dimensional transistor in the prior art. The liquid crystal screen designed based on a three-dimensional transistor includes an array substrate 10, a printed circuit board 20, and a COF (Chip On Flex or Chip On Film) with an integrated circuit 40 mounted thereon. , often called chip-on-chip) 30 , COF 30 is attached between the array substrate 10 and the printed circuit board 20 . Since only one COF 30 ...
