Abstract

A system-on-panel typed liquid crystal display has active layers of single crystalline silicon for fabricating such high speed circuits as drivers, controllers, and central process units. By forming such active layer on a common substrate, the high speed circuits can coexist with lower speed pixel array. As a result, the system-on-panel LCD enables the efficient fabrication of a pixel array, a driver, a controller and a CPU circuit on the same substrate, whereby the fabrication process is simplified and production yields are increased. Moreover, the present invention facilitates the fabrication and manufacture of portable LCD products which are significantly reduced in weight and size because the space occupied by the controller and the CPU circuit is markedly and desirably reduced.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A system-on-panel typed liquid crystal display, comprising: 
 a substrate including at least first, second and third regions;    a pixel array formed using the first region as the substrate;    a driver formed using the second region as the substrate; and    a control unit formed using the third region as the substrate, wherein the control unit includes switching devices having at least one active layer.    
     
     
         2 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the active layer of the control unit is formed of single crystalline silicon.  
     
     
         3 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the pixel array has an active layer formed of single crystalline silicon.  
     
     
         4 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the driver has an active layer formed of polycrystalline silicon.  
     
     
         5 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the pixel array has an active layer formed of polycrystalline silicon.  
     
     
         6 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the pixel array has an active layer formed of amorphous silicon.  
     
     
         7 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the control unit includes a central processing unit.  
     
     
         8 . The system-on-panel typed liquid crystal display of  claim 1 , wherein the driver has an active layer formed of single crystalline silicon.  
     
     
         9 . A system-on-panel typed liquid crystal display, comprising: 
 a substrate including at least first, second and third regions;    a pixel array formed using the first region as the substrate;    a driver formed using the second region as the substrate; and    a control unit formed using the third region as the substrate, wherein the control unit includes switching devices having at least one active layer formed of single crystalline silicon.    
     
     
         10 . The system-on-panel typed liquid crystal display of  claim 9 , wherein the control unit includes a central processing unit.  
     
     
         11 . The system-on-panel typed liquid crystal display of  claim 9 , wherein the pixel array has an active layer formed of single crystalline silicon.  
     
     
         12 . The system-on-panel typed liquid crystal display of  claim 9 , wherein the driver has an active layer formed of polycrystalline silicon.  
     
     
         13 . The system-on-panel typed liquid crystal display of  claim 9 , wherein the pixel array has an active layer formed of polycrystalline silicon.  
     
     
         14 . The system-on-panel typed liquid crystal display of  claim 9 , wherein the pixel array has an active layer formed of amorphous silicon.  
     
     
         15 . The system-on-panel typed liquid crystal display of  claim 11 , wherein the driver has an active layer formed of polycrystalline silicon.  
     
     
         16 . The system-on-panel typed liquid crystal display of  claim 13 , wherein the driver has an active layer formed of polycrystalline silicon.  
     
     
         17 . The system-on-panel typed liquid crystal display of  claim 14 , wherein the driver has an active layer formed of polycrystalline silicon.  
     
     
         18 . The system-on-panel typed liquid crystal display of  claim 14 , wherein the driver has an active layer formed of single crystalline silicon.
