CONTROL SWITCH FOR DRIVING CIRCUIT, ARRAY SUBSTRATE, AND DISPLAY PANEL
A control switch for a driving circuit (200), an array substrate (100), and a display panel (400). The control switch comprises a thin film transistor (220). In the thin film transistor (220), a source branch (231) directly connected to a source lead (210) is a first source branch (232), and a source branch (231) not directly connected to the source lead (210) is a second source branch (233); the channel width between the first source branch (232) and an adjacent drain branch (241) is greater than the channel width between the second source branch (233) and the adjacent drain branch (241).
An array substrate (31), a liquid crystal display panel (3), and a liquid crystal display apparatus (400), the array substrate (31) comprising: a base substrate (300), a first metal pattern layer (310), and a protective layer (320) stacked in sequence, and the array substrate (31) also comprising: a display area (10) and a peripheral area (20) surrounding the display area (10), the peripheral area (20) comprising a binding area (210) and a non-binding area (220), the binding area (210) being positioned on at least one side outside the display area (10); the first metal pattern layer (310) comprises a plurality of conductive contacts (21) positioned in the binding area (210) and spaced apart along a first direction, and a plurality of signal leads (22) in a bent shape positioned in the non-binding area (220); and the protective layer (320) comprises a first insulating layer (321) and a second metal pattern layer (323) arranged in a stack, the first insulating layer (321) being positioned on the side of the second metal pattern layer (323) closest to the base substrate (300) along the direction of thickness of the base substrate (300). The effect of protecting the signal leads (22) can be achieved by means of the addition of the second metal pattern layer (323) at least partially covering the signal leads (22) in the protective layer (320), avoiding the problem of short circuits caused by a gold finger (40).
A liquid crystal panel (10), comprising: a first substrate (100) and a second substrate (200), which are arranged opposite each other, and a liquid crystal molecule layer (300), which is arranged between the first substrate (100) and the second substrate (200), wherein the first substrate (100) comprises a plurality of polarization structures (120); each of the polarization structures (120) comprises a pixel electrode (121) and a common electrode (122); the pixel electrode (121) comprises a plurality of first strip-shaped blocks (121a); the common electrode (122) comprises a plurality of second strip-shaped blocks; the first substrate (100) also comprises a plurality of metal wire grid structures; the plurality of metal wire grid structures are arranged below the common electrode (122); and the metal wire grid structures are connected to each other by means of a metal wire.
