Fig. 1 is a schematic view showing the arrangement position of a conventional liquid crystal display driving integrated circuit wafer. The liquid crystal display shown in the figure is composed of an upper glass 1277798 glass substrate 11 and a lower glass substrate 12. The entire liquid crystal display can be divided into a liquid crystal display region 13, a gate terminal 121, and a source terminal 122. The gate drive integrated circuit chip 123 is disposed on the gate terminal width 121 and the source drive integrated circuit chips 124a, 124b, and 124c are disposed on the source terminal width 122. In the driving integrated circuit chip layout design of the liquid crystal display, the control signals of the source driving integrated circuit wafers 124a, 124b, and 124c are respectively transferred into the liquid crystal display region 13 via the traces 126a, 126b, 126c, 126d, 126e, and 126f. At this time, the liquid crystal display generates a phenomenon in which the brightness of the blocks 131, 132, and 133 is uneven (commonly known as Mura) because the impedance values of the traces 126a, 126b, 126c, 126d, 126e, and 126f are not equal. Therefore, in the design, the integrated circuit chip is usually disposed at a bilaterally symmetrical position, so that the impedance values are equal to avoid the uneven brightness of the blocks 131, 132, and 133, but the obstacle of reducing the product volume is also caused. Referring to FIG. 2, FIG. 2 is a schematic view showing a configuration position of a conventional narrow-edge liquid crystal display driver 1C. The liquid crystal display as shown in the figure is also composed of an upper glass substrate 21 and a lower glass substrate 22. The entire liquid crystal display can be divided into a liquid crystal display region 23 and a terminal web 222, which is different from the first one in that, in order to reduce the product volume, the source drive integrated circuit wafers 224a, 224b, 224c and the gate drive are driven. The integrated circuit wafers 223 are disposed in the same terminal frame 222, that is, arranged on the same side to achieve a narrow margin. However, the arrangement positions of the source drive integrated circuit wafers 224a, 224b, and 224c are not symmetrical. Therefore, the source drives the integrated circuit wafers 224a, 224b, and 224c to the traces 226a, 226b, 226c, and 226d of the liquid crystal display region 23. The difference in length between 226e and 226f is too large, so that the impedance is different and the voltage drop of the output is different, and the angle of rotation of the liquid crystal is also different, so that uneven brightness of the blocks 231, 232, and 233 is likely to occur. 1277798 SUMMARY OF THE INVENTION One object of the present invention is to provide a liquid crystal display that drives a positional arrangement structure of an integrated circuit wafer by using a glass flip-chip bonding and a line array technique to drive a source-driven integrated circuit chip and a gate drive product.
