Description
Technical field
The utility model relates to LCDs field, particularly a kind of touching liquid-crystal display screen of black and white.
Background technology
Universal along with liquid crystal mobile phone and TV, LCDs LCD becomes the most widely used display device gradually, and LCD occupies the leading position in plane display field with advantages such as its volume are little, low in energy consumption, radiationless.The inside of touch LCD screen has touch control electrode and show electrode simultaneously, by integrated for constrained input terminal integral, and can complete control operation in display screen surface.Touch LCD screen can be divided into capacitance plate and touch screens, wherein capacitive touch screen is the ITO(indium tin oxide with electric conductivity pasting layer of transparent on the glass substrate) film, ito thin film etches the circuit of touch control electrode (Touch sensor) and show electrode.The touch control electrode of existing touch-control TFT-LCD is from show electrode on different ITO conductive layers (ito film), and when TFT-LCD makes integrated touch-screen, touch control electrode and show electrode need could realize through at least 3 photoetching, and manufacture craft is loaded down with trivial details.And its touch control electrode section sets has row touch control electrode and row touch control electrode, represents the position of touch with the intersection point of row, column touch control electrode, touch control part separation structure is complicated.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of black and white touch LCD of short in size formula to shield, and touch control electrode independently touches ITO block for several, has touch-control structure simple, the feature that touch-control is highly sensitive.
Technical matters of the present utility model realizes with following technical proposals:
A kind of black and white touch LCD screen of short in size formula, it comprises top glass substrate, lower glass substrate, touch control electrode and show electrode, the upper polaroid of upper surface laminating of described top glass substrate, lower surface has the some touch control electrode of photoetching and show electrode respectively, each touch control electrode is one and independently touches ITO block, the upper surface photoetching of described lower glass substrate has show electrode, the lower polaroid of lower surface laminating; Distance between described touch control electrode and show electrode is greater than 0.1mm.
The black and white touch LCD screen of above-mentioned short in size formula, described touch ITO block draws touch control electrode cabling, the resistance≤10k Ω of touch control electrode cabling.
The black and white touch LCD screen of above-mentioned short in size formula, described show electrode is drawn show electrode cabling, touch control electrode cabling and show electrode cabling parallel arranged.
The utility model be short in size formula black and white IN-CELL LCD(box in the LCD of integrated touch function), its touch control electrode (Touch sensor) with show electrode in same layer ito film.Therefore only need a photoetching just can etch touch control electrode and show electrode in ito film, decrease etching number of times, manufacture craft is simple.Touch control electrode independently touches ITO block for several, show electrode is independently show ITO block, the position of touch control electrode and show electrode is determined by electrode pattern, distance between two electrodes is greater than 0.1mm, can avoid producing interference between each electrode, improve the sensitivity of touch control electrode, reduce the occurrence probability of maloperation.
During existing LCDs design, the blank position generally around show electrode arranges some ITO compensation blocks (compensation block is the block structure that the ito film around show electrode etches), sees the figure in ito film when avoiding not powering up.Because compensation block is that conducting block produces interference when powering up to the touch control electrode around it.Around show electrode of the present utility model, compensation block is not set, to improve the sensitivity of touch-control.By adopting above-mentioned measure, namely the touch control electrode of LCDs contacts contact < 50 grams and just can produce response, and response time < 0.2 second.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, upper polaroid, 2, touch control electrode, 3, top glass substrate, 4, show electrode, 5, LCD panel, 6, lower glass substrate, 7, lower polaroid, 8, alignment film.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises top glass substrate 3, lower glass substrate 6, touch control electrode 2 and show electrode 4, one deck ito film is coated with at described top glass substrate 3 lower surface, in ito film, photoetching has touch control electrode 2 and show electrode 4 respectively, touch control electrode 2 and show electrode 4 are in same layer ito film, and the distance between two electrodes should be greater than 0.1mm.The lower surface of touch control electrode 2 and show electrode 4 pastes alignment film 8.Alignment film can make liquid crystal molecule arrange along the groove of alignment layer surface.The upper surface photoetching of lower glass substrate 6 has show electrode 4, and show electrode 4 upper surface is pasted with alignment film 8.Be LCD panel 5 between two-layer alignment film 8.The upper polaroid 1 of upper surface laminating of top glass substrate 3, the lower polaroid 7 of lower glass substrate 6 lower surface laminating.The thickness of upper and lower base plate glass is 0.4-1.1 millimeter.Wherein upper and lower glass substrate, upper and lower polaroid and LCD panel 5 are for realizing the Presentation Function of LCD.
Each touch control electrode 2 is one and independently touches ITO block, draws touch control electrode cabling, the resistance≤10 k Ω of touch control electrode cabling from touch ITO block.Touch control electrode be integrated in namely segment electrode or public electrode touch ITO block and show electrode on the same layer integrated.Show electrode 4 is a display ITO block, show electrode cabling is drawn from display ITO block, touch ITO block and be used for touch sensitive produce the signal of a capacitance variations, and this signal is delivered in single-chip microcomputer by touch control electrode cabling, calculated the position touched by single-chip microcomputer, make corresponding reaction, when needing display, single-chip microcomputer output signal enters display ITO block by show electrode cabling, completes Presentation Function.The touch control electrode the avoiding existing TFT-LCD intersection point of row touch control electrode and row touch control electrode represents the situation of touch location, and touch control part separation structure is simple, decreases the problems such as wiring.During wires design, touch control electrode cabling and show electrode cabling parallel arranged, do not do and intersect, and can avoid the sensitivity of cabling mutual cross influence touch-control.When the thickness of the thickness+touch control electrode of glass substrate is greater than 1mm, touch-control ITO block is of a size of >=rectangle of 8mm × 8mm.
