LCD panel 100 is formed in structure sequentially coupled of, a polarized plate 10, a color filter (CF) substrate 11, a liquid crystal layer 12, a thin film transistor (TFT) substrate 13 and a polarized plate 14.

[36] In order to cut the large size TFT-LCD panel 100 completed as hereinabove, a polarized plate stripping step is initially performed that removes a portion of a predetermined width to be cut from the each polarized plate 10 provided on a surface above the CF substrate 11 and an opposite surface below the TFT substrate 13.

[38] The TFT substrate 13 is exposed if the polarized plates 10 and 14 around the cutting portion are removed by its lengthwise direction. Since gate lines transferring a scanning signal and data line transferring a screen image signal are configured by innumerably crossing with each other and difficult to perceive by naked eyes, a cutting location setting step sets a portion not damaging the gate line and the data line of the TFT substrate through investigating a portion stripped on the polarized plate stripping step by microscope.

[40] 1st scribe line setting step refers to a step of cutting the CF substrate 11 into its mid- depth along the portion set in the cutting location setting step using a diamond wheel. This step is very difficult and requires a skill of high precision determined by an experience of a technician.

[43] To process a side opposite from a side where a portion of the first scribe line is set, the present step turns over the large size TFT-LCD panel 100 after chucking one end of the large size TFT-LCD panel 100.

[45] The present step sets a 2nd scribe line setting step cutting the TFT substrate 13 into its mid-depth in the portion of the stripped polarized plate 14 bonded with the TFT substrate 13 below along the portion set in the cutting location setting step which

precisely corresponds with the set first scribe line, using a diamond wheel after turning over the large size TFT-LCD panel 100. This step is also difficult and requires a skill of high precision to correspond with the set first scribe line.

[48] A natural crack is made if tempered for 30 minutes to form a natural crack in the scribe lines formed on the CF substrate 11 and the TFT substrate 13 of the large size TFT-LCD panel 100. Then, the air flows into a liquid crystal layer 12. If there is the air flow into the liquid crystal layer 12, the liquid crystal layer 12 is temporarily restricted from flowing out by the flowed in air.

[50] After the 30 minutes tempering step, the CF substrate 11 and the TFT substrate 13 are naturally cracked along the first scribe line and the second scribe line and the present step externally applies a certain amount of force in order to cut the large size TFT-LCD panel 100 along the scribe lines.

[52] The present step is the last step that applies a sealant 30 on a cut portion in the large size TFT-LCD panel 100 and the present invention is completed by applying the sealant 30.

[53] Through undergoing the process hereinabove, the large size TFT-LCD panel 100 is possible to be cut into a plural or multiple numbers without a many numbers of equipment and to meet a desired size of a demander or an operator.

[56] That is, in a large size TFT-LCD panel 100 completed of forming sequentially coupled, a polarized plate 10, a color filter (CF) substrate 11, a liquid crystal layer 12, a thin film transistor (TFT) substrate 13 and a polarized plate 14 below the TFT substrate 13, a cutting location setting step that sets a portion to be cut, a scribe line setting step that sets a first scribe line cutting the CF substrate 11 into its mid-depth along the portion set in the cutting location setting step using a diamond wheel, a turning over step that turns over the large size TFT-LCD panel 100 to a side opposite from a side where a portion of the first scribe line is set after chucking one end of the large size TFT-LCD panel 100, a scribe line setting step that sets a second scribe line cutting the TFT substrate 13 into its mid-depth along the portion set in the cutting location setting step corresponds with the set first scribe line, using a diamond wheel after turning over the large size TFT-LCD panel 100, a tempering step that tempers for

30 minutes to form a natural crack in the scribe lines formed on the CF substrate 11 and the TFT substrate 13 of the large size TFT-LCD panel 100, a cutting step that cuts the CF substrate 11 and the TFT 13 substrate naturally cracked after the 30 minutes tempering step, and a sealing process step that sealing a cut portion formed in the cutting step may configure the present invention.

[59] For example, after undergoing the sequentially processed cutting location setting steps of the first or the second exemplary embodiments through the polarized plate stripping step that removes a corresponding portion of a predetermined width to be cut from the polarized plates 10 and 14 provided on a surface of the CF substrate 11 and an opposite surface of the TFT substrate 13 like the first exemplary embodiment or without the polarized plate stripping step like the second exemplary embodiment, a scribe line setting step sets scribe lines simultaneously cutting the CF substrate 11 and the TFT substrate 13 into their mid-depths along the portion set in the cutting location setting step using a diamond wheel.

[61] The present exemplary embodiment may or may not include the polarized plate stripping step like the first or second exemplary embodiment, and the subsequent steps may proceed in the same sequence as tempering step for the natural crack, cutting step cutting the CF substrate 11 and the TFT substrate 13 and sealing process step .

[62] Meanwhile, when a light from the backlight unit through the TFT-LCD panel 100 processed by the respective exemplary embodiments is illuminated to display a corresponding image, the image may be displayed with an image quality relatively unclear at a portion corresponding to the cutting portion.

[63] Considering this, a light blocking tape 20 may be provided to accomplish the object of the present invention by covering a certain region including the cutting portion against the light illuminated from the back light unit and realizing a clear screen quality at the display region corresponding to the cutting portion.

[64] Here, the light blocking tape 20 may be attached in a range covering any cut portions of the CF substrate 11 and the TFT substrate 13 or the both substrates 11 and 13 as shown in FIG. 7.

10 bonded above with the CF substrate 11 or at a periphery of the polarized plate 14 bonded below with the TFT substrate 14 which are removed with the set cutting portion, may maximize a clearness of the screen quality when the light from the back light unit is illuminated on the cut portion of the TFT-LCD panel 100 completed by cutting into a desirable size.

[70] Further, FIG. 10 and FIG. 11 illustrate an application of the TFT-LCD panel according to the cutting method provided by the present invention. FIG. 10 is a brief exploded perspective view of a liquid crystal display unit. FIG. 11 is a brief cross sectional view of FIG. 10.

[71] As shown in FIG. 10 and FIG. 11, the cut processed TFT-LCD panel 100 equipped with the backlight unit (not shown in drawing) below undergoes a series of course coupling a top sash 2 corresponding to an upper frame with an accommodating frame 3 accommodating the TFT-LCD panel 100 and the backlight unit to be used for the liquid crystal display unit.

[72] Here, when the TFT-LCD panel 100 cut processed in a desired size according to the present invention is received in the top sash 2 and the accommodating frame 3, a realization of a clear screen may be difficult since a slight difference may be produced, not accurately fixing the TFT-LCD panel 100, and producing a flowing phenomena because of the internal difference.

[74] Accordingly, in order to prevent the flowing phenomena, that is the flowing phenomena of the received TFT-LCD panel 100, attaching a plurality of both-faces tape 4 at the outer peripheral edge on the top sash 2 surface and attaching a plurality of both-faces tape 4 at the outer peripheral edge on the accommodating frame 3 surface as well is preferable to completely prevent the flowing phenomena.

[76] Therefore, since a large size TFT-LCD panel may be miniaturized for an application to various video games, monitors or cell phone liquid crystal displays through cut processing the large size TFT-LCD panel without a separate manufacturing line for manufacturing process according to present invention, an industrial applicability expecting an effective reduction of manufacturing facility and its value may be recognized.

If a respondent endorses a trauma exposure, they can score a 0-5 on the PC-PTSD-5, which is a count of "yes" responses to the 5 questions about how the trauma has affected them in the past month. Research in a large sample of VA primary care patients found that a cut-point of 4 ideally balanced false negatives and false positives for the overall sample and for men. However, for women, a cut-point of 4 resulted in high numbers of false negatives. Practitioners may consider a lower cut-point for women in some settings if evaluation resources are available. In contrast, a higher cut-point may be preferable if resources are such that false positives will substantially decrease clinician availability. Because performance parameters will change according to sample, clinicians should consider sample characteristics and screening purposes when selecting a cut-point.

They also use integrated driver chips which tend to support a handful of different resolutions; I guess that if you cut off the half which did not have any driver circuitry, LED backlights, display bias voltage drivers, etc, you might be able to just tell the controller it has a different-sized screen. E.g., take a 128x64 SSD1306 OLED display and cut it into a 128x32 one.

I don"t think it would be very likely to work; there"s probably a lot of very fine connections that you might accidentally bodge or short, even with a high-powered laser cut which maybe re-seals the top/bottom layers along the edge. But in that example, if nothing important broke, I think the SSD1306 driver does support a 128x32-pixel resolution and you might be able to just operate it normally.
