The television technology is an evolving phenomenon. New innovative ideas and concepts are periodically incorporated to the products to make them more sophisticated and consumer oriented. Liquid Crystal Display (LCD) television is one of the latest sensations in the market. In the initial stages of its introduction, LCD was mainly used in portable computers in view of its high cost. But in the course of time, new techniques and methodologies were adopted by the industry in order to make the products more affordable, so that even the low end users will be able to enjoy the luxury of more sensitive television.
LCD television is much sought after by the modern consumers because of its superior features. The sleek, flat screen TVs are now available with High Definition features. The conventional CRT televisions have become obsolete. Sharp pictures and superior quality audio output have made the LCD a favourite choice of the consumers. Energy efficiency is yet another positive aspect of the LCD television.
The High Definition television (HDTV) is a digital mode telecasting system which requires comparatively lesser bandwidth, due to the digital video compression that involves therein. But there is difference between HDTV and HD-Ready television. The High Definition television will have HD tuner built into the system and it requires only hookup antenna to receive HD channels. All modern televisions have HD tuner integrated into it to offer high scan rate display. In the case of HD-Ready television, a separate tuner is required to avail digital telecast. Both analogue and digital channels can be viewed in the HD enabled television. The HD-Ready TVs can have the conventional 4:3 aspect ratio or the widescreen of 16:9 ratios. NTSC tuner will be provided to view analogue programmes. The system is capable of processing and producing High Definition signals at 720p, 1080i and 1080p in digital mode resulting in clear and sharp display. The HD-Ready 1080p television should have minimum resolution (native) of 1920 X 1080 pixels for reception of Full HD signals and to output in the same video format without distortion.
Consumers who are not conversant with the technical aspects of the products, may visit the relevant websites to gather information about the innovative televisions. All modern television sets are provided with the HD-Ready display technology. But it is important that only HD compatible receivers are capable of offering HD display at the viewers’ end. To be precise, television sets may require up gradation to make them capable of receiving high definition signals. An expert dealer will be able to guide the consumer in this respect. The consumers should know that each category of television will have its own advantages or disadvantages, and the choice of any appropriate technology depends on the tastes and preferences of the user.
