Abstract
The utility model discloses a liquid crystal displaying surface plate with a back light source and comprises a circuit plate with a printed circuit, a liquid crystal screen and an indicating lamp. The middle part of the circuit plate is fixedly provided with an inlaying frame bulging from a plate surface in the insulated way, and the frame is inlaid with the liquid crystal screen. An electric conduction supporting strip is connected between the screen and the circuit plate, and the plate surface of the circuit plate in the frame is also uniformly provided with the multiple-color indicating lamp. The surface plate adopts the multiple-color back light source to cause the displaying screen to has the bright color and the rich variability. The dynamic diversified content of an MCU single chip computer programming controlled lattice type liquid displaying screen is adopted, and the liquid crystal displaying surface plate with a back light source is good for displaying the multifunction characteristic of the household appliance.
Description
The utility model relates to the improvement of electrical control panel, specifically is a kind of backlight display panels, and it belongs to the household electrical appliances technical field of auxiliary facilities.
The control panel of commercially available household electrical appliances generally all adopts display panels.This LCD graphical sysmbol is static, and content displayed also is dull, can not show the multi-functional characteristic of household electrical appliances better, so that influences the overall image of household electrical appliances.
The purpose of this utility model is that a kind of novel backlight display panels will be provided.The backlight that this panel has multiple color combination sets off LCD.This LCD will have the displaying contents variation, is rich in dynamics properties.
Task of the present utility model is finished by following technical scheme, developed a kind of backlight display panels, it comprises: the wiring board that has P.e.c., liquid crystal display and pilot lamp, be installed with the frame of inlaying that protrudes from the plate face in the insulation of the middle part of wiring board, assembly has liquid crystal display on this frame, is connected with the conduction lattice framing between this screen and wiring board, also is laid with multi-colour LED on the wiring board plate face in this frame.
Described wiring board, its be by the MCU single-chip microcomputer respectively by line driving chip and row chip for driving, after circuit amplifies, carry out the wiring board of programming Control LCDs.
Described liquid crystal display, it is the lattice liquid crystal display screen.
Described multi-colour LED, it is to connect control by the MCU single-chip microcomputer to show multiple color varying backlight.
The utility model has the advantages that owing to successfully adopt the MCU single-chip microcomputer diversified displaying contents, by the dot matrix driving circuit, be that line driving chip and row chip for driving are carried out programming Control, in dot matrix lcd, show, therefore this display panel has the advantages that to show that icon is various, dynamic, vivid, bright, the multi-functional characteristic that shows household electrical appliances better, more accurately.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the structural front view of backlight display panels;
Fig. 2 is the structure longitudinal section (the A-A cutaway view Amplified image of Fig. 1) of backlight display panels;
Fig. 3 is a backlight structure of liquid crystal display panel rear view;
Fig. 4 is the liquid crystal drive functional-block diagram.
Referring to Fig. 1-3, the backlight display panels of making, it comprises: have the wiring board 1 of P.e.c., liquid crystal display 2 and pilot lamp 3.At the middle part of wiring board 1 by mounting board 6 insulation be installed with protrude from the plate face inlay frame 4.Assembly has liquid crystal display 2 on this frame 4, is connected with conduction lattice framing 5 between this screen 2 and wiring board 1.Also be laid with multi-colour LED 3 on the wiring board 1 plate face in this frame 4.
The key component of this display panels is designed wiring board 1, referring to Fig. 4, this plate 1 be by the MCU single-chip microcomputer respectively by line driving chip and row chip for driving, after circuit amplifies, carry out the wiring board 1 of programming Control LCDs.The liquid crystal display 2 that is adopted is lattice liquid crystal display screens.The multi-colour LED 3 that is adopted is the LBD luminotron.All pilot lamp 3 are connected control by the MCU single-chip microcomputer, thereby show the backlight of polychrome combination and variation.
