Description

Double-deck touch-control monochrome liquid crystal display in box

Technical field

The utility model relates to a kind of monochrome liquid crystal display, more specifically to integrated double-deck touch-control monochrome liquid crystal display in the box of double-deck touch-control electrode in a kind of box.

Background technology

Along with the high speed development of household electrical appliances and continuous renewal and the variation of consumption appliance idea, people improve greatly for the requirement of the display performance of household electrical appliances display device and the touch-control system of man-machine interaction.

In prior art, be usually used in the device of household electrical appliances or industry control demonstration and touch-control, have following several schemes that realize touch-control and Presentation Function:

1, twisted nematic liquid crystal display and external keyboard, adopts two independently devices, jointly completes touch-control and Presentation Function.

2,, on twisted nematic liquid crystal display, laminating condenser type or resistive touch screen, complete touch-control and Presentation Function.

3, the integrated liquid crystal display of touch controllable function: LCD shows touch-control all-in-one machine, below the upper strata of twisted nematic liquid crystal display glass surface, upper strata polaroid, integrated one deck induction electrode, the position of this induction electrode, directly over touch pattern, realize the function that touch-control shows one.

Above traditional scheme has following shortcoming:

The 1st kind of scheme, its components and parts are many, and volume is excessive, and number of clicks and serviceable life are limited.Because liquid crystal display and external connection keyboard generally need to be arranged in same plane, both to occupy certain area, and because external connection keyboard is made up of plastic parts, keyboard conducting resinl and the numerous devices of the corresponding PCB of keyboard, make the thickening of complete machine thickness, therefore, whole demonstration and touch control component are difficult to accomplish frivolous.And sometimes in order to save volume, have to the area of liquid crystal display to be reduced to very little (such as common air-conditioning remote control), this can cause the visuality of liquid crystal display excessively poor, causes certain customers' reading difficulty.And the principle of key board is generally by firmly pressing keys distortion, push conducting resinl, allow upper two carbon electrodes of conducting resinl contact PCB make two carbon electrode short circuits and to realize, but exert oneself for a long time pressing keys, can cause all constantly wearing and tearing of button and conducting resinl, carbon electrode, in the time that the degree of wear is larger, can produce harmful effect to outward appearance, when conducting resinl or carbon electrode may wear to a certain degree, even can occur between two carbon electrodes cannot conducting etc. problem, thereby the life-span of key board is very limited.

The 2nd kind of scheme, although assembly and the display module of touch-control overlap, greatly reduce the volume that the assembly of touch-control takies, because touch-screen is to attach in addition, therefore the integral thickness of liquid crystal display is still partially thick, and the cost of touch-screen is also higher.And because the technique of touch-screen is to increase one deck glass or PET panel, this has also reduced the transmittance of display, display effect is poor.

The 3rd kind of scheme, does not need other assemblies completely, only needs an integrated liquid crystal display for one deck touch-control electrode, has just realized touch-control and Presentation Function simultaneously, has solved the lightening problem of household electrical appliances touch-control and Presentation Function.As shown in Figure 1, this liquid crystal display comprises that liquid crystal 1, framework 2, upper polaroid 3, lower polaroid 4, touch-screen drive lead-in wire 5, a LCD show electrode 6, LCD to drive lead-in wire 7, touch screen electrode 8, a PI both alignment layers 9, the first glass substrate 13, the second glass substrate 14, the 2nd PI both alignment layers 15, the 2nd LCD show electrode 16.But, because touch pattern shows by powering up, therefore need to make in addition one deck touch sensible electrode at upper strata glass surface, and being the two-sided ITO that is coated with two-sided indium tin oxide films by etching, the manufacture craft of touch-control electrode forms, its processing technology is very complicated, and two-sided plating ITO starting material need customization separately, therefore procurement cycle longer, production cost is higher.

Double-deck touch-control monochrome liquid crystal display in a kind of box, comprise liquid crystal cell, upper polaroid, lower polaroid, outer silk-screen touch pattern, it is characterized in that: described upper polaroid is located at liquid crystal cell upper surface, described liquid crystal cell comprises the first glass substrate and the second glass substrate, the first glass substrate and the second glass substrate are stacking, between the first glass substrate and the second glass substrate, be provided with the framework being formed by frame adhesive, in described framework, be filled with liquid crystal, in described liquid crystal cell, be provided with a LCD show electrode, the first touch sensible electrode, the 2nd LCD show electrode and the second touch sensible electrode, a described LCD show electrode and the first touch sensible electrode are all located at the first glass substrate lower surface, the lower surface of a described LCD show electrode and the first touch sensible electrode is provided with a PI both alignment layers, described the 2nd LCD show electrode and the second touch sensible electrode are located at the second glass substrate upper surface, the upper surface of described the 2nd LCD show electrode and the second touch sensible electrode is provided with the 2nd PI both alignment layers, described lower polaroid is located at the second glass substrate lower surface, described outer silk-screen touch pattern is located at the first glass substrate upper surface, and outer silk-screen touch pattern is positioned at the below of polaroid, described the first touch sensible electrode is connected by anisotropic conductive gold spacer with the second touch sensible electrode.

Preferably scheme, described upper polaroid is double-deck TAC therebetween one deck PVA.Wherein, TAC layer is insulating material.

Preferably scheme, described lower polaroid is double-deck TAC therebetween one deck PVA, and upper strata TAC is insulating material, and the TAC of lower floor is conductive material, disturbs with the modular circuit that shields LCDs below.

The utility model beneficial effect is against existing technologies, because liquid crystal display has increased the outer silk-screen touch pattern of thin layer, but do not need to make one deck upper strata touch sensible electrode, greatly simplify technique, do not need to buy in addition the ito glass substrate of two-sided plating tin indium oxide, and the structure of described liquid crystal cell and technique are in full accord with structure and the technique of common monochrome liquid crystal display, do not need to increase any cost and do not have any technology difficult problem, owing to adopting capacitive induction mode, do not need firmly to press as keypad, can realize in theory unlimited click, longer service life, owing to adopting the mode of double-deck touch sensible electrode, therefore sensing capability is stronger than using the sensing capability of independent one deck touch sensible electrode, owing to having cancelled external keyboard, can utilize the area of saving, what the area of liquid crystal display was done is larger, be beneficial to and see displaying contents clearly, and because the button of induction is integrated in liquid crystal cell, silk-screen touch sensible pattern above, therefore the pattern seen is the position of button, and outer screen printing pattern almost 360 degree orientation, full visual angle all can be seen, therefore when operation, eyes are being seen display, having eliminated traditional structure need to not stop to switch sight line between display and keyboard, once the poor keyboard that just do not see of light, the easily shortcoming of maloperation, obtain better man-machine interaction effect.
