The 40 inch TV Buying Guide
A 40 inch LED TV is the perfect fitting for those rooms that allow 5 – 6.6 feet of distance between the users and the television. It does not only provides size benefits for typical larger television rooms, such as maybe a living, bed room or basement, but provides users with outstanding features in a television such as: contrast, brightness, color range and rapid scene change responses. Selecting a 40 inch LED TV, provides a different approach compared to LCD or CCFL televisions, which offers a lower quality picture and a higher energy consumptions than a LED. If you are to go with a 40 inch television for your space sufficient and adequate room, a 40 inch LED TV would be the best option.
What is a LED TV?
A LED TV is a flat panel display that uses energy efficient LED (Light Emitting Diodes) back lighting (except edge-lit models) to provide varying intense illumination over a wide area for imaging and optic applications, versus cold cathode fluorescent, used in CCFL and LCD TVs, which takes a greater amount of voltage to operate and which light intensity cannot vary. This backlight semiconductor device, emits visible light when an electrical current passes through it. It is provided in three various styles.
The Three Types of a LED Televisions:
- Dynamic Backlight – Which controls LEDs, individually or in cluster, which controls light and color level intensities to multiple aspects of the screen.
- Edge- Lit – LEDs are formed around the rim of the screen, using a diffusion panel to evenly spread light behind the screen. This type is the most used and allows for a thinner TV design for a less weighted item.
- LED back lighting – Brightness of LEDs are not controlled individually. This type is also known as the Full array or the Direct-Lit LED.
Features of a 40 inch LED TV:
- Lighting Design – Varies in lighting design manufacturing – Comes in a RGB backlight (combines for a white light) or simply just a white backlight. The RGB backlight produces a better richer quality picture and adjusts better, which can create for various color variations, especially various white hues, that can constitute to a more realistic looking picture. RGB back lighting is more expensive than the two, but, definitely worth the additional money that is shelled out.
- Local Dimming (Many LED TVs have this feature available) – Controls the output of LEDs – Rather than being on at full strength at all times, LEDs are dimmed or turned off during the appropriate times of proper management.
- Small LEDs – Smaller and more powerful than fluorescent, provides a higher quality lighting technique – Produces deeper blacks and greater saturated colors. Although more powerful, it is smaller, and requires less power. It can convert power into light much more efficiently and allow less light leakage, which is prone to produce fuzziness in a picture.
Benefits of 40 inch LED TV:
- Mercury Free – The toxic, mercury is commonly used in many other TV, which is known to cause immune, enzyme and nervous system damages in humans and causes deformities and deaths to animals.
- Lower Power Consumption – Because less power is needed to illuminate the diodes, it makes for a lower energy usage, which can affect monthly energy costs.
- Fast cut on time – Starts up in full lit and bright mode, without having to wait for a television warm-up process, before fully functioning.
- Bright Pictures – Can become bright enough for seeing screen containments in extreme bright conditions.
Because LED TVs are flat, they use less space in a room, which can allow for greater distance between viewers and the television. Although a 40 inch item, It is still light enough in weight, to mount on a wall without falling.
The price of a 40 inch LED TV may be a little higher – versus a 40 inch LCD TV – but viewers will experience greater quality and can benefit greater in the long run, as LED televisions use less energy consumption to operate. Prices can differ – at a reasonable amount – at about 27%. As competition increases, expect percentage to shrink and prices to fall steadily as time ages.
Input and output connective options, included with a 40 Inch LED TV:
- HDMI Input – Provides a full 1080p picture and digital sound.
- USB Input – Connects USB devices
- RF Input – Radio frequency socket that receives radio signals, mostly for connecting cable television.
- Component – Receives analog video from a signal sending unit.
- Component (Av) – Transmits analog audio and video information through a single signal.
- Ethernet – Links TV to Local Area Network (LAN)
- PC Audio Input – Receives sound from a computer
- PC/DVI Audio In – Receives encrypted digital audio signals from media players and other devices.
- Digital Audio Out (Optical) – Transmits digital audio streams out to a receiving device.
Disadvantage of a LED Television
- It is more expensive than a LCD TV, up to about 50%.
- It is light in weight, but the “LED backlight” type, can make for a more difficult approach for wall mounting, due to the weight of its body.
Your typical 40 inch LED TV will weigh about 16 – 19 pounds without the included stand, and about 24 lbs with it.
Overall, a 40 Inch LED television can provide users with a large, high quality, color rich picture display, that is energy efficient, with the appropriate and sufficient connection types, to best receive and send audio and video information between devices, for the best LED television experiences. The incredible features and benefits of a LED television – each available type included – makes for enjoyable TV experience for all viewers, of any age.
