Description
Technical field
The utility model relates to a kind of liquid crystal display module of capacitor touch controlled key, be specifically related to the two-sided ITO cabling of a kind of employing, use ITO electrically conducting transparent film figure as the keying sensor (ON CELL) of electric capacity touch screen at the upper surface of LCD, FPC two sides crimps, and adopts glue entirely to fit and PC plastic casing and LCD screen be integrated into an overall liquid crystal display module.
Background technology
LCD screen is as principal display device, be widely used in the numerous areas such as national defence, industry, family expenses, communal facility, industrial control instrument display requires higher, if industrial instrument has button demand, the way in past increases instrument area, design mechanical key, the problem brought is: instrument volume increases, viewing area separates with key zone, and the mechanical key life-span is short, affected by environment larger simultaneously.
As adopted capacitor touch controlled key liquid crystal display module, above shortcoming can be overcome, viewing area and control zone unite two into one, reduce instrument volume, compared with traditional mechanical key, capacitance touch induced key is attractive in appearance, durable, life-span is long, it has been overturned traditional mechanical key and has controlled, as long as touch gently, just can realize the switch control rule to button, quantize to regulate even direction controlling, present capacitance touch induced key is widely used in mobile phone, DVD, in the consumer products such as washing machine, adopt full coating technique simultaneously, make specific inductive capacity constant, capacitance touching control is more stable, the transmitance of light is higher.
Utility model content
The purpose of this utility model is to provide a kind of keying liquid crystal display module of capacitor touch controlled key, adopt two-sided ITO cabling, use ITO electrically conducting transparent film figure as the keying sensor (ON CELL) of electric capacity touch screen at the upper surface of LCD, FPC two sides crimps, there is capacitive touch function, display and touch-control unite two into one, and compact conformation, volume is little.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of keying liquid crystal display module, comprise one to be equipped with 0.8 inch LCD display by the plastic housing one of PC material injection, the fixed COG IC chip of described LCD display nation, drive 74x64 lattice pixels, a described COG IC chip is drawn by FPC, it is characterized in that, adopts two-sided ITO cabling, use ITO electrically conducting transparent film figure as the keying sensor of electric capacity touch screen at the upper surface of LCD display, be connected to keying IC input end by FPC; Keying IC on FPC by SMT technique paster, is drawn by FPC terminal and is connected with outside MCU; COG IC chip fixed with nation in LCD display below described FPC is connected, and FPC adopts two sides crimping, by two ito surfaces up and down of LCD display, draws LCD control IC terminal and keying sensor terminal respectively.
Described COG IC chip internal integrated LCD Controller, lcd driver, DC/DC power boost circuit.
Compared with prior art, the utility model has following beneficial effect:
The utility model adopts COG nation to determine technology, and compact conformation volume is little, super low-power consumption; LCD liquid crystal display upper slice uses two-sided ITO (ON CELL technology), there is capacitive touch function, sturdy and durable, reaction velocity is fast, save space, operation is directly perceived, display and the advantage such as touch-control unites two into one, and the full attaching process of employing glue, specific inductive capacity is high, transmitance is high.
Accompanying drawing explanation
Fig. 1 shows structural representation of the present utility model.
Number in the figure illustrates: 1:PC transparent plastic shell; 2: optical cement;
3:ITO electrically conducting transparent film image (keying sensor); 4: touch-control IC; 5:FPC; , 6:LCD display screen; 7:COG IC chip (LCD control IC).
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Figure 1, a kind of keying liquid crystal display module, comprise one to be equipped with 0.8 inch LCD display 6 by the plastic housing 1, of PC material injection, the fixed COG IC chip 7 of described LCD display nation, drive 74x64 lattice pixels, a described COG IC chip 7 is drawn by FPC 5, and described LCD display 6 upper surface is also coated with one deck ITO electrically conducting transparent film figure 3 and is connected to keying IC 4 input end as keying sensor by FPC 5; Keying IC 4 on FPC 5 by SMT technique paster, is drawn by FPC terminal and is connected with outside MCU.The plastic housing 1 of PC material injection is shaped as an entirety by the full nation that fits of optical cement 2 and LCD display 6.
Further, described LCD display adopts: the large stretch of surface of LCD adopts two-sided ITO, and one deck ITO electrically conducting transparent film figure that the large stretch of upper surface of LCD display is coated with is connected to keying IC as keying sensor by FPC.
Further, FPC is crimped onto two ito surfaces up and down of LCD screen sheet respectively, draws LCD control IC terminal (COG IC chip 7) and keying sensor (ITO electrically conducting transparent film image 3) terminal respectively.
Further, an entirety is shaped as by the plastic housing of PC material injection by optical cement and the LCD screen nation that entirely fits.
Keying IC 4, LCD control IC (COG IC chip) 7 is by FPC and outside MCU connecting communication, when touch PC case surface, LCD upper surface sensor sensing capacitance variations, notice keying IC, keying IC is by calculating, position coordinate value is passed to MCU, and MCU, according to prior software programming content, controls LCD display displaying contents or controls other peripheral hardware to carry out action.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
