It is equipped with X-axis electrode at every position in the ranks of corresponding the multiple through-hole in the second substrate, it is corresponding the multiple logical
Y-axis electrode is equipped at position between every column in hole；The touch tablet is covered on the LED display, each LED hair
Light pipe is protruded into correspondingly in each through-hole.
Further, the LED light tube is without departing from the through-hole.
Further, the second substrate includes two layers of plate body, and the X-axis electrode and the Y-axis electrode are arranged at two
Between the layer plate body.
Further, the surrounding of the second substrate exceeds the surrounding of the first substrate, the X-axis electrode and institute outward
State the both ends of the Y-axis electrode thickness from the part beyond the first substrate of the second substrate along the second substrate respectively
Direction is across the second substrate and around the behind of the LED display.
Further, the circuit integration of the touch tablet is on the circuit board of the LED display.
The beneficial effects of the present invention are embodied in:
The present invention realizes display function with LED display, touch function is realized with touch tablet, by the second of touch tablet
Through-hole is opened up on substrate, to cooperate the luminescence display of each LED light tube, by leading to X-axis electrode and Y-axis pole layout multiple
Each item in hole is in the ranks between each item column, and to guarantee the realization of touch function, the configuration of the present invention is simple is easy to implement, low in cost,
With extraordinary application prospect.

Fig. 3 is the cross-sectional view of one embodiment of the invention LED touch display screen.
Fig. 4 is the cross-sectional view of one embodiment of the invention LED touch display screen.
The label of each component in attached drawing are as follows: 11 first substrates, 12LED luminous tube, 21 the second substrates, 211 through-holes, 22X axis
Electrode, 23Y axial electrode.
Specific embodiment
It is next below with reference to the accompanying drawings that the present invention will be described in detail.It should be noted that in the absence of conflict, in the application
Embodiment and embodiment in feature can be combined with each other.
Referring to Fig. 1 to Fig. 3.
LED touch display screen of the present invention, including LED display and touch tablet；
The LED display includes first substrate 11, and the first substrate 11 shines equipped with multiple LED arranged vertically and horizontally
Pipe 12；The touch tablet includes the second substrate 21 and electrode (electrode namely following X-axis electrode and Y-axis electrode), and described second
Multiple through-holes arranged vertically and horizontally 211 are provided on substrate 21, every row of corresponding the multiple through-hole 211 in the second substrate 21
Between position at be equipped with X-axis electrode 22, be equipped with Y-axis electrode at the position between every column of corresponding the multiple through-hole 211
23；The touch tablet is covered on the LED display, and each LED light tube 12 protrudes into each through-hole correspondingly
In 211.
" in the ranks " and " between column " region between adjacent rows and two column through-holes is respectively indicated.
The present invention realizes display function with LED display, realizes touch function with touch tablet, LED display is i.e. using existing
There is structure, does not improve, and in order to which cooperated with LED display screen realizes touch function, the present invention opens in the second substrate of touch tablet
If through-hole, to cooperate each LED light tube to protrude into, the light that such LED light tube issues will not be blocked, and avoiding, which influences LED, shows
The display of screen；
Inventive touch plate realizes touch function using the principle of projecting type capacitor, and the axial coordinate formula of projected capacitive incudes single
Variable matrix: the discrete row and column of axial coordinate formula sensing unit is mutually perpendicular to the draw runner intersected with two and realizes that X-axis draw runner, Y-axis are sliding
Item detects the capacitance variations of each lattice sensing unit；After the present invention opens up through-hole in the second substrate of touch tablet, X is not influenced
The laying of axial electrode and Y-axis electrode, if be arranged in each item of multiple through-holes in the ranks each item column between.
In specific implementation, using by the ITO of moth erosion, ITO layer forms multiple horizontal and vertical electrodes, i.e. X-axis by eating into erosion
The individual chips that row/column is interlocked simultaneous with sensing function further can also be used into electrode 22 and Y-axis electrode 23.
In one embodiment, the LED light tube 12 is without departing from the through-hole 211.It designs, can shine to LED in this way
Pipe plays a protective role.
In one embodiment, the second substrate 21 includes two layers of plate body, the X-axis electrode 22 and the Y-axis electrode 23
It is arranged between two layers of plate body.It designs, can play a protective role to X-axis electrode and Y-axis electrode, while again can in this way
Enough guarantee the stability of X-axis electrode and Y-axis electrode.
In one embodiment, as shown in figure 4, the surrounding of the second substrate 21 exceeds the four of the first substrate 11 outward
The both ends of week, the X-axis electrode 22 and the Y-axis electrode 23 exceed the first substrate 11 from the second substrate 21 respectively
Part along the second substrate 21 thickness direction pass through the second substrate 21 and around the behind of the LED display.
It designs in this way, bending can be generated because bypassing the second substrate to avoid the both ends of X-axis electrode and Y-axis electrode.
In one embodiment, the circuit integration of the touch tablet is on the circuit board of the LED display.It designs in this way,
Overall structure is more succinct, reduces volume.
It should be understood that example as described herein and embodiment are not intended to restrict the invention, this field only for explanation
