Track Pad Desire HTC Z

HTC Desire Z equipped with the track pad section at it front. So in the front have 4 main menu of Android smartphone, and one underneath the trackpad. Maybe some people will ask what is the function of the that trackpad, because the HTC Desire Z screen already has the ability to touchscreen. I think the trackpad is important because it is rather difficult for people with big fingers for change the wrong writing at screen capacitive navigation. With a trackpad, we can be helped to shift to left, or right, or up or down according to what we want with more precisely.

Some people feel comfortable with the default keyboard that can appear on screen as wide as 3.7 inches, but for me still a physical keyboard is quite helpful to write in a more precise and faster, so the error rate can be reduced. But it will consequently the weight of the HTC Desire Z to be more weight than a smartphone that does not use a physical keyboard.

For cars owner, it is become imperative to have the main light source which is bright enough. Average car production today already have the bright lights. Usually the owners are still often change their car lights to be brighter than ever before, some of them use hid light (High Intensity Discharge).

HID headlights for car, also known as Xenon headlights. This is the type of lamp that can produce bright light with a higher light intensity. Usually to determine the brightness level of HID lamps are mentioned in Kelvin degrees (K). Because HID require high voltage, then the HID lamp are equipped with a driver known as Ballasts who set the voltage to stabilize the size required by this HID lamp. 

As mentioned above, that the HID types of light units are use Kelvin degree (K), because the color affect of HID light will be different for each Kelvin degree like can be seen in the data below:

• Yellow light 4300K
• White light is slightly yellow 5500K
• White light 6500K
• White-blue light 8500K
• Blue light is a little purple 10000K
• Purple light 12700K
• Light Pink 15000K

We should choose the HID light with caution, because the type of light should be in conformity with the requirements we need. There are some light that may not be in accordance with the conditions we need. But if we are correct in choosing the type lampur HID, then we will will feel very comfortable to drive, especially at night. Choosing a manufacturer of HID light also have to be careful, because a good hid light manufacturer and store will provide good warranty and guarantee.
