Description

Touch panel module

The invention relates to a panel module, in particular to a touch panel module in which the width of the wiring region of the transparent conductive layer is not integral multiple of the opening width of the black matrix layer.

As smart phones or tablets become more and more popular in the society, the key technologies for achieving this epoch-making product are mainly liquid crystal display technology and touch sensing technology, and the products made by integrating these main technologies can be simply divided into backlights. Modules, color filters, and sensing circuits. The backlight module is used as a light source for providing a touch display, and each pixel structure in the color filter is used for providing display color, and the sensing circuit is used for sensing the touch portion.

Although the product has been successfully mass-produced and can be accepted by consumers at the same time, there are still many spaces that can be improved in terms of products. For example, in the induction circuit technology, if the remaining image and the display detection portion are not properly With the matching process, the display array and the sensing pattern matching will produce a grating phenomenon, which will affect the viewing quality of the display. In the case of a serious grating phenomenon, the display may not be viewed normally.

The grating phenomenon occurs because the opening of the black matrix layer is the opening of the single primary color of the display. If the light source is driven by the opening for a certain distance and then passes through the sensing pattern, the sensing pattern is generally etched by indium tin oxide. The resulting pattern can therefore be divided into a trace area and an etched area. However, although the trace area has good light transmittance, it cannot be better than the etched area without the light transfer medium, so the light source is then incident through the opening to the induction. When drawing graphics, pass the line area and pass The portion of the over-etched region produces a difference in light transmission, or as an optical path difference, which causes a grating phenomenon to occur.

The generation of the grating phenomenon will cause the viewer to feel visual abnormality when viewing the display. The effect of the light source actually emitted by the single opening of the black matrix layer is not very obvious, but the light source generated by the multiple openings at the same time will strengthen each other. The effect of the light source between the two makes the effect more and more obvious.

In order to improve the effect of the light source effect, one way is to reduce the distance between the black matrix layer and the sensing circuit as much as possible, although this method can solve the problem technically, but the material is in the material of the specifications used. The same size but thinner and thinner approach will result in a higher technical height of the parts required, which in turn will increase costs to the downstream end from the upstream end of the industrial chain. In addition, since the thinness is relatively high, the brittleness of the material is relatively increased. Therefore, in the field of partial touch liquid crystal display applications, the product with high safety requirements does not expect the thickness of the touch liquid crystal display to be too thin.

In view of this, for the innovation of today's touch-screen LCDs, how to develop a novel touch display that conforms to universal security to improve the defects caused by the above is one of the industries and companies that cannot be ignored. important topic.

A main object of the present invention is to provide a touch display panel module that utilizes the difference between the opening width of the black matrix layer and the width of the trace region of the line group region to achieve the visual anomaly caused by the overlapping of the light source effects.
