Alternative thin film transistors for liquid crystal displays

Abstract

Alternative thin film transistors for liquid crystal displays are disclosed. The alternative transistors can be used for panels of displays such as liquid crystal displays (LCDs), especially those having alternative pixel arrangements. These transistors can be oriented on a panel of an LCD using different, non-traditional configurations, while addressing misalignment and parasitic capacitance.

1 . A device having a double thin film transistor, the device comprising:
 at least one drain electrode for the double thin film transistor;   a gate line having at least two gate electrodes for the double thin film transistor; and   a source line having at least one source electrode for the double thin film transistor, wherein a crossover is formed by the drain electrode and a gate line.   
   
   
       2 . A thin film transistor comprising:
 a source comprising a source electrode connected to a source line;   a gate comprising at least a first gate electrode and a second gate electrode, said first and second gate electrodes connected to a gate line;   a drain connected to said source electrode, said drain comprising at least a first drain electrode and a second drain electrode;   wherein there is at most a single crossover between said gate and said source.   
   
   
       3 . The thin film transistor of  claim 2  wherein there are at least two crossovers between said gate and said drain. 
   
   
       4 . A device comprising a plurality of thin film transistors as recited in  claim 2 . 
   
   
       5 . A pixel comprising:
 a thin film transistor, said thin film transistor connected to a gate line and a source line;   a pixel element connected to said thin film transistor; and   at least one extra metal line interposed between said gate line and said pixel element.
