LARGE-SIZE DISPLAY SCREEN AND MANUFACTURING METHOD THEREOF

摘要

Disclosed are a large-size display screen and a manufacturing method thereof, wherein the large-size display screen comprises a front display plate (1) and a thin film transistor backplate (2). The thin film transistor backplate (2) is provided with row scanning lines (21, 71), column scanning lines (22, 72) and a thin film transistor array for driving the front display plate (1). The thin film transistor backplate (2) is formed by splicing together a plurality of thin film transistor backplate units (20), each of the thin film transistor backplate units (20) being provided with via holes (24) in one-to-one correspondence with the row scanning lines (21, 71) and the column scanning lines (22, 72). Both of the row scanning lines (21, 71) and the column scanning lines (22, 72) on each of the thin film transistor backplate units (20) spliced to one another lead to the back of the thin film transistor backplate (2) through the corresponding via holes (24) for electrical connection. The large-size display screen and the manufacturing method thereof avoid the occupation of the space at the front side of the display screen, realize seamless splicing of display screen units, reduce costs, increase the yield of good products and are suitable for mass production.
