Abstract
A vertical-orientation liquid crystal display integrating the touch control function comprises an upper layer transparent ITO glass substrate and a lower layer transparent ITO glass substrate and is characterized in that the outer surface of the upper layer transparent ITO glass substrate is provided with a transparent indium tin oxide induction electrode. Compared with a vertical-orientation liquid crystal display with the integrated touch control function in the prior art, the vertical-orientation liquid crystal display has the advantages that due to the fact that the induction electrode is integrated on the liquid crystal display, a layer of indium tin oxide coating film with the thickness of about 25 nanometers is additionally arranged, but an external keyboard is eliminated, dozens of square centimeters of product surface area can be saved, and the size of the overall machine is greatly shrunken; due to the fact that the vertical-orientation liquid crystal and the double-shaft compensation film are adopted, optical path difference in all visual directions can be compensated for, and therefore high-contrast display effect can be achieved nearly in any visual angle. Due to the adoption of the capacitance-type induction mode, a user does not need to press the vertical-orientation liquid crystal display like pressing the keyboard, infinite times of clicking can be achieved theoretically, the service life is longer, and better human-computer interaction effect can be achieved.
Description
Technical field
The utility model relates to a kind of liquid crystal display of household electrical appliances, more specifically to a kind of vertical orientation liquid crystal display of integrated touch controllable function.
Background technology
Along with the high speed development of electrical appliance industry and the continuous 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 thereof.
As shown in Figure 1, in prior art, for household electrical appliances, show and the device of touch-control, normally by these two of external keyboard and common twisted nematic liquid crystal displays independently device form.Wherein twisted nematic liquid crystal display mainly comprises following structure: the transparent ito glass of the transparent ito glass in upper strata and lower floor, on the inside surface of the transparent ito glass of levels, be coated with polyimide, between two layers of polyimide, be perfused with twisted nematic liquid crystal layer, on the outside surface of the transparent ito glass of levels, attach wired polaroid.
There is following shortcoming in above-mentioned such structure:
1, volume is larger.Because liquid crystal display and external connection keyboard generally need to be arranged in same plane, both to occupy certain area, complete machine area must be increased accordingly.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), visuality is too poor, causes certain customers' reading difficulty.
2, element is many, except liquid crystal display, also will have keyboard plastic parts, keyboard conducting resinl and the corresponding PCB of keyboard, and these all want mold, makes integral member cost and die cost high.
3, twisted nematic liquid crystal display poor contrast, narrow viewing angle can only be seen display pattern clearly in less scope.Household electrical appliances such as washing machine, electromagnetic oven particularly, because the position of installing fixes, as figure tri-, for the different consumer of height, the line of vision angle of observation is also all different, if narrow viewing angle cannot be seen some consumer clearly displaying contents.
4, the principle of key board is to be generally out of shape by the pressing keys of exerting oneself, upper two carbon electrodes of extruding conducting resinl contact PCB make electrode short circuit and realize, permanent firmly pressing keys, button and conducting resinl, carbon electrode are are all worn and torn, affect outward appearance, even when conducting resinl or carbon electrode may wear to a certain degree, can occur cannot conducting functional bad generation.Thereby the life-span of key board is limited.
5, man-machine interaction impression is poor.External keyboard is in the situation that the light such as night are poor, human eye cannot be seen clearly, cause operation inconvenience, such as a lot of air-conditioning remote controls just exist this problem, in the situation that not turning on light night, be difficult to keyboard to operate, even add background light under keyboard, the effect of improvement is also general, and adds background light and also can further strengthen the manufacturing cost of product.
Utility model content
Technical problem to be solved in the utility model is the shortcoming large for prior art volume, cost is high, display effect is poor, the life-span is limited, man-machine interaction sense is poor etc., a kind of vertical orientation liquid crystal display of integrated touch controllable function is provided, and the vertical orientation liquid crystal display of this integrated touch controllable function can make that complete machine structure is less, display comparison degree is better, visual sees that the angle life-span wider, that click is longer, man-machine interaction sense is better.The technical scheme adopting is as follows:
A vertical orientation liquid crystal display for integrated touch controllable function, comprises the transparent ito glass substrate of the transparent ito glass substrate in upper strata and lower floor, it is characterized in that: the outside surface of the transparent ito glass substrate in described upper strata has the transparent induction electrode of tin indium oxide.
Scheme preferably, the thickness range of described indium tin oxide transparent induction electrode is 20-30 nanometer.
Scheme preferably, the outside surface of the transparent ito glass substrate in described upper strata is provided with upper strata elliptic polarization mating plate, upper strata elliptic polarization mating plate is positioned at indium tin oxide transparent induction electrode top, and the structure of upper strata elliptic polarization mating plate is double-deck TAC therebetween one deck PVA, and the upper strata of TAC is biaxial compensation film.Wherein, TAC layer adopts insulating material.
Scheme preferably, the outside surface of the transparent ito glass substrate of described lower floor is provided with lower floor's elliptic polarization mating plate, and its structure is double-deck TAC therebetween one deck PVA, and the upper strata of TAC is biaxial compensation film.Wherein, TAC layer adopts conductive material.
Scheme preferably, the inside surface of the transparent ito glass substrate in described upper strata and the transparent ito glass substrate of lower floor has respectively LCD to show conductive electrode and polyimide alignment layers, between upper and lower polyimide alignment layers, be injected with vertical orientation type liquid crystal layer, the anisotropy that described vertical orientation type liquid crystal layer inside includes specific inductive capacity is negative liquid crystal.
The utility model beneficial effect is against existing technologies, due to liquid crystal display integrated induction electrode, having increased thickness is only the indium oxide layer tin plated film of 25 nanometer left and right, but cancelled external keyboard, the product surface that can save dozens of square centimeter is long-pending, and the volume of complete machine is greatly reduced; Owing to having adopted vertical orientation liquid crystal and biaxial compensation film, the optical path difference of each line of vision is all compensated, therefore almost at any visual angle, can realize the display effect of high-contrast; Owing to adopting capacitive induction mode, do not need firmly to press as keypad, can realize unlimited click, longer service life in theory; 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 on display pattern, therefore shown pattern is the position of button, in the time of operation, eyes are being seen display, do not exist traditional structure need to not stop like that to switch sight line between display and keyboard, and when light is poor, do not see the situation of keyboard, easy maloperation, thereby obtain better man-machine interaction effect.
