They make the blood vessels around brain tumours less leaky and so reduce swelling in the brain. When your brain tumour is first diagnosed, you are most likely to have steroids to reduce swelling. After successful treatment for the brain tumour, your specialist will slowly reduce your steroid dose.he tumour takes up space inside your skull and can increase the pressure inside your head. The pressure increase can cause headaches, sickness and fits (seizures). After successful treatment for the brain tumour, your specialist will slowly reduce your steroid dose.
TFT displays are a type of liquid crystal display in which the transistor controlling the pixelâs crystal is etched into a layer of amorphous silicon deposited on the glass (see Figure 1). As in an IC process, very small transistors are geometrically formed.
An LED-backlit LCD display is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs. LED-backlit LCD TVs use the same TFT LCD (thin film transistor liquid crystal display) technologies as CCFL-backlit LCD TVs. Picture quality is primarily based on TFT LCD technology, independent of backlight type. While not an LED display, a television using this display is called an âLED TVâ by some manufacturers and suppliers.
