msk tft display manufacturer

Dr Pan: Hello, Greg. TFT LCD module is one of the best LCD technology. We can simply consider it as TFT+LCD+LED backlight, and monochrome LCD module consists of LCD+LED backlight. An image on an LCD we can see is composed of pixels. TFT is the abbreviation for thin film transistor and it controls the R, G, B colors of each pixel respectively on the surface of LCD.

TFT LCD is a high standard product and it is not well customized as monochrome LCD. But still, it has a variety of options to meet the customers’ requirements.The sizes range from 1.44 inch to 130.0 inch;

The thin film transistor-liquid crystal display (TFT-LCD) has been used all over the world. Although the manufacture process of TFT-LCD was highly automated, employees are hired to do manual job in module assembly process. The operators may have high risk of musculoskeletal disorders because of the long work hours and the repetitive activities in an unfitted work station. The tools of this study were questionnaire, checklist and to evaluate the work place design. The result shows that the participants reported high musculoskeletal disorder symptoms in shoulder (59.8%), neck (49.5%), wrist (39.5%), and upper back (30.6%). And, to reduce the ergonomic risk factors, revising the height of the work benches, chairs and redesigning the truck to decrease the chance of unsuitable positions were recommended and to reduce other ergonomics hazards and seta good human machine interface and appropriate job design.

The present invention relates to a display device, and more particularly, to a liquid crystal display (LCD) device and a method for manufacturing the same.

Ultra-thin sized flat panel displays having a display screen with a thickness of several centimeters or less, and in particular, flat panel LCD devices, are widely used in monitors for notebook computers, spacecraft, and aircraft.

Such LCD devices have low power consumption and are easy to carry. In this respect, the LCD device is receiving much attention as an advanced display device that can substitute for a cathode ray tube (CRT).

An LCD device includes a thin film transistor (TFT) substrate, a color filter substrate, and a liquid crystal layer sealed between the TFT substrate and the color filter substrate. The LCD is a non-light-emitting device that can obtain an image effect based on electro-optical characteristics of the liquid crystal layer.

In other words, a TFT array and pixel electrodes are formed on the TFT substrate, while a black matrix pattern, a color filter layer, and a common electrode are formed on the color filter substrate. The TFT substrate and the color filter substrate are bonded to each other by a sealant such as epoxy resin.

A driving circuit is connected with the TFT substrate using a tape carrier package as a medium. The driving circuit generates various control signals and signal voltages to display images.

The development and application of TFT-LCD industries have been accelerated in accordance with an increase of the dimensions and increase of the resolution of LCD devices. To increase the productivity and ensure the low cost, many efforts have been continued in view of simplified process steps and an improvement of yield.

Another object of the present invention is to provide an LCD device and a method for manufacturing the same in which a color filter layer is formed on a pixel electrode in a state where a TFT is not driven.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, an LCD device according to the present invention includes first and second substrates, a TFT formed in a predetermined region on the first substrate, a pixel electrode formed in a pixel region on the first substrate, a color filter layer formed on the pixel electrode, a black matrix pattern formed in a region other than the pixel electrode, and a liquid crystal layer formed between the first and second substrates.

To further achieve these and other advantages and in accordance with the purpose of the present invention, a method for manufacturing an LCD device having a pixel region defined by gate and data lines, includes forming a TFT on a first substrate, forming a black matrix pattern in a region other than the pixel region, forming a pixel electrode in the pixel region, and forming a color filter layer on the pixel electrode. In forming the TFT, when forming source and drain electrodes, an n+ layer between them is removed. When removing the n+ layer, a gate insulating film in a pad region is also removed by an etching process to remove a gate pad.

In another aspect of the present invention, in forming a TFT, a metal layer for the source and drain, an n+ layer for an ohmic contact, and a semiconductor layer of a-Si are patterned, and the patterned metal layer is selectively removed to form source and drain electrodes and at the same time remove an n+ layer between the source and drain electrodes. When removing the n+ layer, a gate insulating film in a pad region may also be removed to expose a gate pad.

Consequently, the number of masks required when forming a plurality of patterns on the substrate is minimized to reduce the manufacturing cost, and a color filter material can be electrodeposited by applying a voltage to the data line only in a state such that the TFT is not driven.

As shown in FIG. 3, the LCD device according to the first embodiment of the present invention includes first and second substrates 31 and 31 a, a TFT and a pixel electrode 45 formed on the first substrate 31, a color filter layer 47 formed on the pixel electrode 45, a black matrix pattern 43 formed in a region other than the pixel electrode 45, a common electrode 32 formed on the second substrate 31 a, and a liquid crystal layer (not shown) formed between the first and second substrates 31 and 31 a.

The TFT includes: a gate electrode 33 apatterned on the first substrate 31; a gate insulating film 35 formed on an entire surface of the first substrate 31, including the gate electrode 33 a; a semiconductor layer 37 of amorphous silicon (a-Si) patterned on the gate insulating film 35; source and drain electrodes 41 band 41 cformed on the a-Si layer 37; and an n+ layer 39 for ohmic contact formed between the source and drain electrodes 41 band 41 cand the a-Si layer 37.

As described above, in the second embodiment of the present invention, the black matrix pattern 43 and the color filter layer 47 are formed on the substrate in which a TFT and the pixel electrode 45 are arranged. When etching the metal layer to form the source and drain electrodes 41 band 41 c, the n+ layer of a channel portion and the gate insulating film on the gate pad are simultaneously removed to minimize the number of masks and simplify the process steps.

Meanwhile, the connecting pattern 91 connects the data line 41 awith the drain electrode 41 cthrough an upper portion above the gate line 33. When a color filter material is electrodeposited to form a color filter layer in a later process, the connecting pattern 91 serves to electrodeposit the color filter material by a voltage only applied to the data line in a state such that the TFT is not driven. The connecting pattern 91 forms a single body with the data line 41 aand the drain electrode 41 c. Alternatively, the connecting pattern 91 may be formed by a separate process.

As shown in FIG. 8d, a light-shielding material is formed on the entire surface including the pixel electrode 45 and then patterned to remain on a region other then the pixel electrode 45, so that a black matrix pattern 43 is formed. At this time, the light-shielding material is patterned to expose the connecting pattern 91. This connecting pattern 91 allows the color filter material to be electrodeposited on the pixel electrode 45 with only the voltage applied to the data line, without driving the TFT, by connecting the data line 41 awith the drain electrode 41 cthrough the upper portion above the gate line 33. Once the color filter material is electrodeposited, the connecting pattern is removed to electrically open the data line 41 aand the drain electrode 41 c.

Subsequently, as shown in FIG. 8e, the color filter material is electrodeposited on the pixel electrode 45 to form the color filter layer 47. At this time, if a voltage is applied to the data line 41 ain a state that the TFT is not driven, the voltage is transferred to the pixel electrode 47 through the connecting pattern 91 so that the color filter material can be electrodeposited.

As described above, in the third embodiment of the present invention, the number of masks can remarkably be reduced. Also, since the color filter material can be deposited in a state that the TFT is not driven, it is possible to prevent characteristics of the TFT from being changed.
