All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
This embodiment provides a display module assembly, includes:
a first substrate 10 and a second substrate 20 which are oppositely arranged, wherein the first substrate 10 comprises a first conductive area which comprises a plurality of first patterned ITO points 40; the second substrate 20 includes a second conductive region, which includes a plurality of second patterned ITO dots 50, and which is disposed opposite to the first conductive region,
a plurality of conductive dots 60, the first patterned ITO dots 40 and the second patterned ITO dots 50 being electrically connected through the conductive dots 60;
and a plurality of patterned dummy dots 70, wherein the patterned dummy dots 70 are disposed on peripheral edge portions of the inner surfaces of the first substrate 10 and the second substrate 20 which are oppositely disposed, so that distances between the inner surfaces of the first substrate 10 and the second substrate 20 which are oppositely disposed are the same.
Preferably, the frame 30 is glued to two sheets including relative setting, forms accommodation space between relative setting's two sheets of gluing frame 30 and the relative setting of first base plate 10 and second base plate 20, and the potential difference is zero all the time in the accommodation space. When the accommodating space reaches electrostatic balance, the potential difference is zero, and in long-time operation, the ITO shielding layer 80 and the circuit inside the display module group can not form a coupling electric field, so that the display screen can keep normal display. The containing space is used for injecting liquid crystal material, when voltage is applied, the liquid crystal material is driven by an electric field between two electrodes to cause the arrangement direction of liquid crystal molecules to change so as to control the projection or shielding function of a light source, and light and shade change is generated between a power switch and a switch, so that an image is displayed.
Preferably, the glue frame 30 is an epoxy glue frame 30. The structure of the LCD box is designed to make a channel between electrodes in the epoxy frame 30.
Preferably, the plurality of first patterned ITO dots 40 are in a fence type in the first conductive region; a plurality of second patterned ITO dots 50 are in a fence pattern in the second conductive region.
Preferably, the plurality of patterned dummy dots 70 are in a barrier type at both end portions of the inner surfaces of the first and second substrates 10 and 20 disposed opposite to each other.
Preferably, the first substrate 10 is provided with a Gen layer on the side facing the second substrate 20.
Preferably, the conductive dots 60 are conductive gold balls. The conductive gold ball is formed by electroplating a layer of metal with good conductivity on a spherical and elastic high polymer material, the common diameter of the conductive gold ball is 5-8 microns, and the conductive gold ball has certain elasticity and is compressible.
Preferably, the second substrate 20 is provided with an ITO shielding layer 80 on a side away from the first substrate 10.
An equivalent capacitance, say capacitance 1, will form between the patterned ITO dots and dummy dots 70;
another equivalent capacitance is formed between the Dummy dot 70 and the ITO shielding layer 80, which is assumed to be a capacitance of 2;
according to FIG. 3, when a voltage waveform is applied to the patterned ITO dots, the dummy dots 70 will induce some charge until the dynamic balance of the electric field, referred to herein as equilibrium state 1, is reached. When equilibrium state 1 is reached, the display in this area is normal.
According to FIG. 4, when the dummy dots 70 are charged, equilibrium state 1 is not reached, and a coupling electric field is formed due to the dielectric property between the dummy dots 70 and the ITO shield 80, and a dynamic equilibrium, referred to as equilibrium state 2, is reached with time.
According to fig. 5, when the capacitor 1 reaches the saturated equilibrium state 1, the capacitor 1 is not charged any more; however, the coupling electric field (the capacitor 2) does not reach the balance 2, at this time, the capacitor 2 will produce a reverse potential, and reversely charge the capacitor 1, so as to destroy the balance state of the capacitor 1, and as time is accumulated, the reverse charge of the capacitor 1 becomes larger and larger, and with the circuit design of this embodiment 1, the potential difference in the accommodating space formed between the first substrate 10 and the second substrate 20 which are oppositely arranged and the two rubber frames 30 which are oppositely arranged is always zero, and when the reverse voltage exceeds the threshold voltage of the liquid crystal, the problem of redundant display cannot occur.
