    • A display device (100) of a domestic appliance includes a printed circuit board (PCB) (102) and a support (112) fixed on the PCB (102) and disposed with several loopholes (110), in which the support (112) is made of an light-tight material; light-emitting diodes (LEDs) are disposed on positions on the PCB (1202) corresponding to the loopholes (110), a light guide part (116) is integrated on the support (112), and the light guide part (116) is made of a light guide material and includes light guide posts (114) filling the loopholes (110). No assembly clearance exists between the light guide part (116) and the support (112) that are formed integrally, so the light can be well obstructed, and be avoided being leaked out from adjacent loopholes (110), thereby avoiding an optical crosstalk phenomenon caused by an assembly problem of the light guide part (116) and the support (112).
    • 家用电器的显示设备(100)包括印刷电路板(PCB)(102)和固定在PCB(102)上并且设置有多个漏洞(110)的支撑件(112),其中支撑件(112) 由不透光材料制成; 发光二极管(LED)设置在对应于漏洞(110)的PCB(1202)上的位置上,导光部件(116)集成在支撑件(112)上,导光部件(116)是 由导光材料制成,并且包括填充漏洞(110)的导光柱(114)。 导光部(116)和支撑体(112)之间不存在整体形成的组装间隙,因此能够良好地遮蔽光,避免从相邻的漏洞(110)漏出,从而避免光学串扰现象 由导光部分(116)和支撑件(112)的组装问题引起。
