A system for displaying images includes a multi-gate thin film transistor (TFT) device including an active layer, first and second gate structures, and first and second light-shielding layers. The active layer is disposed on a substrate in a pixel region. The first and second gate structures are disposed on the active layer. The first and second light-shielding layers are disposed between the substrate and the active layer. The active layer includes first and second source/drain regions and first and second channel regions. The first light-shielding layer corresponds to a first lightly doped region and laterally extends under at least a portion of the first channel region. The second light-shielding layer corresponds to the second lightly doped region and laterally extends under at least a portion of the second channel region.

Multi-gate thin film transistor device

An organic light emitting diode (OLED) display and thin film transistor (TFT) manufacturing method thereof are disclosed. According to the present invention, poly-silicon layers for forming active areas of non-driving TFT (e.g. peripheral circuit TFT and switch TFT) and driving TFT used in the OLED display are respectively made by using standard laser crystallization method and non-laser crystallization method or low energy laser crystallization method. Therefore, the peripheral circuit TFT has excellent electrical performance such as high carrier mobility, while the OLED-driving TFT has good stability so that the resultant display can operate with improved luminance uniformity.

An image display system and manufacturing method are disclosed. According to the present invention, the image display system comprises a substrate, a switching TFT, a driving TFT, a photo sensor and a capacitor. A buffer layer is formed on a substrate. A separation layer is formed in a first area for forming a switching TFT, but no heat sink layer is formed thereon. A heat sink layer is formed on a second area for forming the driving TFT, the photo sensor and the capacitor, and then, the separation layer is formed thereafter. The present invention can form poly silicon layers with different crystal grain sizes on the first area and on the second area in a single laser crystallization process by utilizing the heat sink phenomenon of ELA with or without the heat sink layer. Therefore, the image display system of the present invention can operate with good luminance uniformity.
