One of the primary attractions of CRT televisions today is their superior color accuracy. Furthermore, their low price point and durability make them an excellent option for budget shoppers who desire something long-lasting and reliable. Those searching for an excellent TV should opt for a CRT model rather than something less costly but subpar regarding picture quality. Not only are LCD and LED displays more expensive to maintain than plasma monitors, but they also require frequent cleaning or dusting of their displays. CRT TVs also boast greater viewing angles than modern flat screens this allows multiple people in various parts of the room to watch at once comfortably.Äue to reduced demand, older models tend to be much less costly than newer ones. These TVs allow you to experience sharper details in light and dark scenes without experiencing blurring or distortion from pixelation. Most significantly, older TVs provide more natural images than modern versions.ĬRTs utilize an electron gun to generate images on the screen, giving these TVs superior resolution than flat screens typically do. More Natural PicturesÄ®ven though CRT TVs are no longer made and have largely been replaced by flat-screen models, there is still good reason to buy one today. Overall, investing in a CRT TV today will give you plenty of value for your dollar regardless of its price or features. While CRTs may display images with less clarity than higher-end sets, if your entertainment needs consist primarily of standard definition content such as cable TV or VHS tapes, then this wonât matter. You may also consider purchasing used ones for additional savings without compromising quality.ĬRTs also boast excellent picture quality, sometimes more so than LCDs depending on how well they have been maintained. This makes it easy to find something suitable to your budget and viewing preferences. Furthermore, due to using less power or energy, they boast lower operating costs than LCDs or plasmas.ĬRT televisions represent excellent value because there are so many models on the market - from traditional tube variety models to flat screen versions. This makes them an excellent way to save money without compromising picture or audio quality. While other televisions may have become more prevalent over time, CRTs remain much less costly than their more common alternatives like LCDs or plasmas. Read on to understand why CRTs make such an excellent investment! Cost-EffectiveĬRT TVs remain an economical choice today thanks to their cost-effective nature. This article will highlight the top ten reasons why purchasing a CRT TV may be ideal for you today. Though old, these TVs still provide certain advantages that modern models cannot match. You may consider cathode ray tube (CRT) televisions if you want a reliable yet cost-effective television solution.ĬRT televisions date back to the late 1890s, making them one of the oldest technologies in television sets. With so many choices on the market, it can take time to select one. Find an expression for the voltage V(h) that is required such that the electron beam hits the phosphor screen at the desired height h.Shopping for a new TV can be an intimidating experience. c) What is the vertical position, z ,of the electron when it exits the electric field region at y = d? d) What is the velocity (v,(t) and v,(t)) of the electron when it exits the electric field region at y = d? e) Finally, the electron beam is required to hit the phosphor screen at y = L +d, at a vertical position z = h. Assume the electron has charge q and mass m. Find an expression for the electron's coordinates z(t) and y(t). b) Assume that at time t = 0 the electron beam starts at z(0) = y(0) = 0 with initial velocity v, (0) = v, and v,(0) = 0. *Hint: You can assume that the plates are infinitely large for calculation purposes. For d <= y <= d by two parallel plates with a potential difference Vo. In this problem you will analyze the electrostatic system. Typically, the electron beam is deflected using magnetic fields, however, some designs also use electrostatic fields. By rapidly âpainting" the beam across the phosphor screen, images (and hence movies) could be formed. The CRT essentially steers an electron beam onto a phosphor coating that is located on the glass screen. Cathode Ray Tube (30 pts): Older television monitors used cathode ray tubes (CRT) to generate images on a screen.
