LCD TV PK plasma TV

● LCD TV PK Plasma TV

1. Contrast: The contrast of plasma is mostly 3000:1, 4000:1 and 5000:1 at present, even as high as 10000:1, and the contrast of LCD TV is basically between 400:1—1200:1. The LCD TV screen is brighter than the plasma in a very plentiful environment such as lighting in a store, but in a relatively dark home environment, the LCD will be dazzling, such as lowering the brightness and loss of image layering and dark images. detail. Compared to the plasma screen, it is softer, clearer, and clearer.

2. View angle: Due to different lighting principles, plasma and LCD TVs can reach 170 degrees from the viewing angle. However, when the LCD TV is viewed at a large declination angle, the screen will have a color cast phenomenon, while the plasma does not have this problem. Therefore, plasma TV is more suitable when the whole family is watching together or when the living room area is large.

3. Dynamic Sharpness/Response Speed: Dynamic sharpness refers to the visual clarity perceived by the human eye when viewing a moving picture. The response speed is the reaction time of the television circuit to the motion picture processing. Plasma has excellent dynamic resolution and extremely fast response speed (less than 1ms). Both the static landscape scene and the fast sports scene can be clearly displayed without smearing. The response speed of the liquid crystal is between 8-25ms. When playing a low-speed moving picture, the picture quality is more delicate than that of the plasma. However, the dynamic picture performance is far inferior to the plasma. When the fast moving picture is played, the trailing phenomenon and the image overlap are likely to occur. This can cause visual fatigue and affect vision health.

4. Power consumption: From the product data point of view, the power of the 42-inch plasma is generally around 350W, which is higher than the general power of the same size liquid crystal. However, due to different lighting principles, the power consumption of plasma and liquid crystal on different screens is also different. Plasma is the self-illumination of the screen pixels, and the power consumption changes as the brightness of the screen changes. 350W refers to its power at peak brightness. The liquid crystal always emits light regardless of the picture, so the power consumption is fixed. For example, when playing a brighter variety show, the plasma consumes more power. With ordinary brightness pictures (news, sporting events, TV shows, etc.), plasma and liquid crystal are similar; when the picture is dark, such as when playing a movie, the plasma work Consumption is lower than LCD.

5. Service life: At present, plasma and LCD TVs can achieve a display life of 60,000 hours (50% display power attenuation), but in fact, after 16,000 hours, plasma and LCD TVs will have a certain amount of screen display capacity attenuation, according to the attenuation rate. The actual usage varies from 10% to 40%.
