一种LCD显示装置及LCD显示装置的引光方法
技术领域
本发明涉及一种通过引光来加强背光的LCD显示装置和LCD显示装置的引光方法。
背景技术
LCD(Liquid Crystal Display,液晶显示器)为平面超薄的显示设备。LCD分为折射式LCD和透光式LCD。折射式LCD不用背光,在强光下显示屏能明显显示,而在晚上弱光下看不清楚,需要加背光;透光式LCD必须有背光才能看清文字,在晚上弱光就能看清楚,而白天强光照射到LCD显示屏上则看不清楚,此时需要很强的背光源。背光源是用来确保LCD显示屏背后发出光亮的光源装置,背光源的亮度对LCD显示屏所显示文字的清晰度有着直接的影响。由于背光源的高亮度会导致LCD电子设备的电池耗电太快,因此,人们希望设计出既可以清晰显示又省电的LCD显示装置。

在本发明的一实施例中,所述导引光线出射面位于背光板的侧面,朝向背光板的侧面,所述背光板的侧面透光。
在本发明的一实施例中,所述导光板和所述背光板为一体式的导光结构。
本发明还提供一种LCD显示装置的引光方法,包括以下步骤:
(S1)经由导光板接收外部光线;
(S2)将接收的外部光线导引至LCD显示装置,作为LCD显示装置的加强背光。
在本发明的一实施例中,所述步骤(S2)中导光板将接收的外部光线导引至背光板的背面。
在本发明的一实施例中,所述步骤(S2)中导光板将接收的外部光线导引至LCD显示屏和背光板之间。
在本发明的一实施例中,所述步骤(S2)中导光板将接收的外部光线导引至背光板的侧面。
在本发明的一实施例中,所述步骤(S2)中导光板将接收的外部光线导引至背光板。
有益效果:本发明提供的LCD显示装置,在不增加耗电的情况下,通过导光板引入外部光线以加强背光,并提供具有该LCD显示装置的引光方法,其经由导光板接收并引入外部光线以加强LCD显示屏的显示强度,达到在强光下自动补强背光,使得太阳光照射到本LCD显示屏时,仍可以清晰显示而且省电。
