液晶电视品牌排名 1创维2 海信3康佳4 LG 5 索尼6三星7夏普8 TCL 9 长虹10飞利浦--------------------------------------------------------------------------------------------------------1.海尔32寸液晶电视L32R1 市场价格:¥3189元 L32R1液晶电视功能:△色彩长久不失真△Hi-Fi动感音质△时尚造型△DSM超强睿驰三核芯引擎△九段色彩调节△专业级数码音响△HDMI高清流媒体接口△高光珍珠黑靓丽面板△绿色环保△可调式旋转底座:海尔宝蓝液晶电视采用的流线型宝石蓝线条设计利用了光的透射、折射原理及塑料件的半透明性,使其呈现光柱和片体效果,给人高贵、温馨的感觉。此外,这款产品的外壳采用的是UV罩光漆,是目前最好的一种喷漆技术,克服了传统液晶电视的“桔子皮”现象,(液晶面板由于喷涂工艺的缘故机壳面板会出现凹凸不平的现象俗称“桔子皮”现象)并且达到了环保无污染的优点。L32R1是海尔新推出的宝蓝系列中的一款,这点从包装上就不难看出,整个外包装都以黑色和蓝色为主色调,显得很上档次。打开包装箱,里面东西并不算多,都是一些诸如说明书、遥控器,以及AV视频线之类的常规附带品。海尔L32R1采用了LPL的液晶屏幕,拥有1366×768的分辨率,6000:1的动态对比度,1000nits的亮度和4ms的相应时间,可以有效的组织托尾和残影现象的产生。这款电视还拥有120帧数码自然动感技术和XWCG-CCFL冷阴极背光技术,在画质方面有了一定程度的提升。L32R1最大的特点是具备“广色域校准”技术,能够随时修复屏幕的色域,这就像给电视做“面膜”,即使长时间播放都不会出现偏色、失真等不良现象,它的清晰度比传统广色域电视还要提高30%,能够有效保护用户的眼睛。此外,它还具有0.001ms超快响应速度可以保证运动画面无拖尾现象发行。色调风格则展示出目前大多数平板产品都喜欢采用的浓郁风格,特别是黑暗细节色的表现非常抢眼。===================================================================================2.海尔32寸液晶电视L32F1 市场价格:¥3079元 L32F1液晶电视功能:△S-DSM+睿驰三核芯超强处理引擎△防眩光专利技术△3A图像优化技术△蓝光魅影Fashion Menu技术:海尔L32F1液晶电视拥有强劲的核心和实用的配置,3千出头的价格也算实惠。近日打算购买小尺寸平板的家庭不妨到卖场了解一下这款产品。在规格方面,海尔L32F1液晶电视配备了优质高清面板,拥有1366×768分辨率,4ms急速响应时间。采用S-DSM+睿驰三核芯超强处理引擎,3A图像优化技术,以及海尔独家的蓝光魅影Fashion Menu技术,还原原始画质,色彩更加真实。虽然该款液晶电视机面向的是低端市场,但其性能可以与部分中端机型媲美。在音质方面,海尔L32F1液晶电视采用九段均衡数字音质,超空间动态音箱,增强了声音的临场感。接口方面,海尔L32F1液晶电视配备了2路AV输入、AV输出、DVD分量输入、S端子、耳机插口、PC接口、HDMI等接口,足以满足日常使用的需求。----------------------------------------------------------------------------------------------------------------------------------如何挑选液晶电视众所周知,今年平板电视的市场将迎来一个爆发性的增长,而面对各大厂家此起彼伏的降价声,广大消费者可能很茫然,到底怎样选液晶产品,怎样才能花最合适的价钱购买到性价比最高的产品呢?大家应该知道液晶电视的好坏主要取决由三个方面:一是液晶面板、二是背光管的质量和排列顺序、三是电路板即色彩处理电路。现在世界上液晶面板的主要供应商为三星、LG、富士通等厂家。但消费者在购买液晶时几乎所有厂家都说自己品牌采用的是这三家供应商的,但实际上很多厂家用的并不是这些屏,消费者如何辩别好屏和坏屏呢?第一可以让导购员把液晶菜单打出来,观看菜单中亮度的数值,因为液
