Description
Technical field
The display panel and touch interfered the utility model is related to display field more particularly to a kind of low radio frequency shows mould
Group.
Background technology
In the intelligent communications equipment such as mobile phone, the driving IC of the display panel in touch-control display module at work, in
Signal line in portion's clock frequency and internal booster circuit and wiring board can all cause radio frequency interference, lead to penetrating for mobile phone
Frequency module leads to the problem of EMI, directly increases the noise floor of sensitivity test, and the increase of noise floor causes mobile phone spoke
Receiving sensitivity decline is penetrated, signal weakens, and the quality and user for influencing mobile phone use.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of display panel of low radio frequency interference,
Interference will not be generated to the radio frequency reception of the intelligent communications equipment such as mobile phone at work.
The utility model also provides a kind of touch-control display module.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of display panel of low radio frequency interference, on one side binding have driving IC and be connected with wiring board, the driving
It is pasted with copper foil on IC and/or the wiring board, the copper foil and the circuit board electrical connection are to be grounded.
Further, dew copper region is provided on the wiring board, the copper foil is pasted and is electrically connected to the areas Lu Tong
Domain.
Further, the conducting total impedance in the copper foil and dew copper region is less than 0.5 Ω.
Further, it is provided with insulating protective layer between driving IC and the copper foil.
Further, further include the upper substrate and lower substrate of opposing seal setting, filled out between the upper substrate and lower substrate
Filled with liquid crystal material.
Further, it is provided with upper polaroid in one side of the upper substrate far from lower substrate, the lower substrate is far from upper
It is provided with down polaroid in the one side of substrate.
A kind of touch-control display module includes the display panel of above-mentioned low radio frequency interference.
The utility model has the advantages that：The display panel covers one layer of copper foil on the driving IC, is formed
EMI shielded layers can end to fall the signal line in the clock frequency and booster circuit and the wiring board in the driving IC
Work be powered during the interference signal that generates, prevent interference signal from leaking the radio frequency mould to intelligent communication terminals such as mobile phones
Block generates radio frequency interference when receiving radiofrequency signal；Also, the copper foil is by being electrically connected the wiring board, by electrostatic conduct to
Ground terminal on the wiring board, when eliminating ESD the driving IC in electrostatic coupling place by being influenced.
Description of the drawings
Fig. 1 is the schematic diagram of the display panel of low radio frequency provided by the utility model interference.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in Figure 1, a kind of display panel of low radio frequency interference, includes the upper substrate 1 and lower substrate of opposing seal setting
2, liquid crystal material is filled between the upper substrate 1 and lower substrate 2；The upper substrate 1 is provided in the one side far from lower substrate 2
Upper polaroid 3, the lower substrate 2 are provided with down polaroid 4 in the one side far from upper substrate 1；It is bound on the side of its lower substrate 2
There is driving IC 5 and be connected with wiring board 6, copper foil 7, the copper foil 7 are pasted on the driving IC 5 and/or the wiring board 6
It is electrically connected with the wiring board 6 to be grounded.
The display panel covers one layer of copper foil 7 on the driving IC 5, forms EMI shielded layers, can end to fall the drive
The signal line in clock frequency and booster circuit and the wiring board 6 in dynamic IC 5 produces during working and being powered
Raw interference signal prevents interference signal from leaking and is produced to the radio-frequency module of the intelligent communication terminals such as mobile phone when receiving radiofrequency signal
Raw radio frequency interference；Also, electrostatic is conducted connecing to the wiring board 6 by the copper foil 7 by being electrically connected the wiring board 6
Ground terminal, when eliminating ESD the driving IC 5 in electrostatic coupling place by being influenced.
Dew copper region is provided on the wiring board 6, the copper foil 7 is pasted and is electrically connected to the dew copper region, described
Dew copper region is connected with ground terminal handles electrostatic grounding；Since the driving IC 5 is not GND, it is preferred that the drive
It is dynamic to be provided with insulating protective layer between IC 5 and copper foil 7, for reducing influence of the copper foil 7 to the driving IC 5.
The conducting total impedance in the copper foil 7 and dew copper region is less than 0.5 Ω.
Embodiment two
A kind of touch-control display module, including described in embodiment one low radio frequency interference display panel.
The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot it therefore be interpreted as the limitation to the utility model patent range, as long as using the form institute of equivalent substitution or equivalent transformation
The technical solution of acquisition, shall fall within the scope of the present invention.
