Digital cameras, pda, color screen mobile phones, laptops and many other modern portable multimedia devices using LCD or TFT displays.
The LCD represents the LCD display, while the TFT represents the thin-
Thin Film Transistor-
Usually just incorrectly called LCD because they look the same as the end user and they work the same way.
They have very low power consumption and lightweight design, and are ideal for these applications.
These two factors are essential for portable devices such as cameras and pda, because they are designed to be portable without causing obvious burden, which means the design of the hardware, the battery that powers it must maintain a minimum weight.
Although many common problems of LCD screens have been solved over the years, the display of portable devices has been greatly improved due to the basic design of this display, one thing that still causes problems is that there is extra light.
As mentioned above, both LCD and TFT generate displays on the same basic principle.
In the color display, the entire screen is on the back
Always light up with white light.
Change the color of a point that makes up the screen-a pixel -
It varies by varying degrees of opacity.
The pixel itself can block all light, but, say, Green, a transparent green filter is created.
However, the white light shines through this and only the green part passes through the pixels to reach the eye of the audience.
The Pixel can also change to red or blue, or it will look almost black if it is as opaque as possible.
The LCD screen has never been perfect for the back.
The bright design, and the need for pixels to be able to switch from full off (transparent and white) to full open (almost opaque and black), are all in less than 100 of space in 1 second, an opaque state can never be created perfectly.
As a result, the LCD display always presents a slight gray color instead of a black color.
Compared to your TV, or better yet, the CRT computer monitor can be provided, and the LCD screen has what is called a poor \"contrast \".
This is further exacerbated when light from outside the screen (such as light from the sun) or a fluorescent lamp on the top of the head shines back on the surface of the screen.
The result is that the contrast is worse, causing all colors to look washed out and blurry.
Because of this, your LCD screen is more difficult to see under bright lights.
Most people who find themselves in this situation quickly learn simple remedies to tilt the display down, or cast shadows on the screen with their hands.
This is always inconvenient, and in the case of digital photography, a good angle and a stable hand are required, which is usually not an option.
This is a simple but valuable product line to solve this problem.
The LCD parasol is very simple, it is a hood mounted on the LCD display that can block all peripheral light from shining the screen.
For devices such as laptops and laptops, they have various shapes and sizes, and they have smaller versions for cameras and PDAs.
Some of the more expensive products have a foldable telescopic cover that completely covers all sides of the display, even from the front you will see.
Instead, they installed an eyepiece on this face that zoomed in the image projected from the LCD display, and the photographer looked at the LCD display.
The simpler design has less restrictions on the devices they will fit well.
They are not perfect because the light can still come in from behind the viewer, however, if the light is strong enough, in many cases the photographer\'s head will cast the necessary shade on the screen.
A few interesting examples are worth taking a closer look.
There are many similar products, but the service is good for example.
The first is the rogue h200.
This LCD shade is specially designed for compatibility with Nikkon and Canon cameras, but should be good for most 1. 5 to 2. 5-inch LCD display.
This is a simple nylon box that gradually becomes thinner when it comes out and is fixed on the camera with a pair of Velcro and elastic bands.
When not in use, it is easy to fold flat and can be easily placed in the camera bag.
The retail price is less than $20, and if you do any photography in a bright place or outside, it is an accessory that can easily and quickly pay for yourself.
The second project, rogue e-
The Clipse E2000 is a sunshade made for laptops and laptops.
Forming a black nylon hood on all sides will not significantly hinder the user\'s viewing area or significantly blur the keyboard, which can be a useful product if you are using a laptop outside.
Like camera hooligans, it can be quickly folded into flat and easily stored in the laptop case without adding a lot of volume or weight.
To use it, simply slide it over the upright display and you can go.
$40, a bit expensive, however, it might be worth it for what it offers.
Due to the nature of the LCD and TFT display work, bright light is still one of the most inconvenient obstacles to their use.
Whether it\'s for your camera, multimedia phone, laptop monitor, or any other device that uses a color LCD monitor, the parasol addresses this weakness in a practical, cost-effective way, and
