Description of the Invention: The present invention relates to an optical detection system and method, and more particularly, A detection system and method for use in a liquid crystal display (LCD) color filter process. [Prior Art] • In recent years, display technology has flourished, and thin film transistor liquid crystal displays (TFT-LCDs) have been successfully used in personal entertainment, family life, and various occasions. It is well known that consumers are pursuing perfect visual enjoyment, so producers are highly demanding on the color of the product. Among them, • color filter (c〇l〇r filter) plays a direct or indirect role in the color rendering, contrast, and brightness of TFT-LCD. The infrastructure of a TFT-LCD panel is to sandwich a layer of liquid crystal in two glass substrates. After the color filter is attached to the Liduan LCD panel, a thin film transistor is fabricated on the rear TFT panel. If a voltage is applied to the transistor, the liquid crystal will turn, and when the light passes through the liquid crystal, a halogen is produced on the front panel. A backlight module is located behind the TFT_Array panel to provide a light source. Color (5) ambiguity > 1 gives each one a noisy color. Therefore, combining each of the different colors of the color is the image of the front end of the panel. Once the color filter is mad, the face is not perfect. In order to avoid the discovery of color filters in subsequent processes, the time and cost of the process, the time and cost of the process, the testers are producing different colors (-the most common colors of red, blue and green) After the color slab is 5 1322888 'Patent No. 095 丨 13834, the replacement of this patent (without scribe version, April 1998) will carry out related tests, such as detecting the uniformity of the thickness of the color filter film. , or color uniformity and other plagues. If it is found to be defective, it can be removed or reproduced immediately. As shown in FIG. 1 , the conventional detection method is to use a white light source 1 照射 to illuminate a first surface 12 ′ of one of the detected color filters 11 and the detecting person is located at a second surface 14 opposite to each other. Identification by the naked eye. Since this method uses a white light source', the color filter seen by the inspector 13 is a red, blue, and green three-color pixel interlaced. The examiner 13 must recognize the color flaws by the naked eye, but it is difficult to find out which color of the color is mad in the three-color pixel interlaced pattern. In addition, it is difficult for inspectors to infer which process is a problem. Although it is customary to do dense color metrics on color to find out the process in which the problem occurred, this method is extremely labor intensive and time inefficient. In addition, there is a similar technique in which a color light film is inspected by means of light reflection, i.e., the light source is positioned on the same side as the tester for detection with respect to the filter to be detected. However, this method is not suitable for large-sized color light-emitting sheets, because the incident and reflected light sources are not uniform, and it is impossible to easily detect the target. Furthermore, there is another conventional technique to replace the above-described visual inspection with a photosensitive device to detect flaws. Then, a white light source with adjustable brightness is used, and the detected color filter 'received by the photosensitive device to receive the detection signal transmitted from the color light-passing sheet' is transmitted to a detecting device for analysis. Compared with the use of the naked eye detection method, the method is more accurate, but the light source is only a white light source. After passing through the color filter, the gray scale size and proportion of the color patterns of the color filters on the color filter cannot be adjusted. It is not possible to carry out cockroach detection for all color enamel patterns at the same time in order to observe the presence or severity of cockroaches. 0 6 1322888 Patent Application No. 095113834 Replacement (without scribe version, April 1998) The above situation will be slightly explained. If a detecting device is disposed on a detecting platform, a detecting light source disposed on the same side as the detecting device is irradiated with a color filter to be detected, which is red, green, and ambiguous after being reflected by the color light passing sheet. The gray scale value of the checker is 1〇〇, then, if the gray level value of the detection after receiving the reflection of the light source is 6〇, it means that the red and green pixel patterns have similar dark areas.瑕 瑕 (referred to as "Black ss (BlackU) ss) ^: Only this - detected on the blue pixel pattern, because there is no gray-scale contrast, the thief can not exist. Light, in order to synchronously adjust the gray value of the red, green, and blue enamel patterns (for example, synchronously increase the height of the three HO, 14G, 1GG) 'to detect the blue scorpion pattern, if the detection device at this time, the The gray level value of the light source after the shot is 14. It means that the blue pixel pattern has a similar free zone (referred to as "self-deficiency (Article (10))"), but this is detected in red and green. On the prime pattern, the helmet-like method shows the possible flaws due to the absence of gray-scale contrast. ",, * Because of the cost of the color filter, the total cost of the entire LCD display is a relatively large proportion. If the above-mentioned scarf is not accurate, all the possible red, green, j: prime patterns are all crazy. (ie, "bright area" and "dark area" mad)", so that the fatigue of the product continues to invest * necessary follow-up process, this light time wasted. In the process of the color filter, the red, green, and syllabus are sequentially executed in the _ engineering, and if some of the color plaque patterns that have been attached are not yet completed, It is also necessary to set a position to shorten unnecessary silking fees. Therefore, for the manufacture of LCD displays, a simple pick-up = inspection, set (four) and positive-selling inspection === shaft-up manufacturing 7 No. 09M13834 patent application specification replacement (no-line version, April 1998) 】 Car ί ί Ϊ ΐ ΐ 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 本 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色 彩色The color of the element (2) 3 contains one, then the device, the detection of the number of light generating devices, first set. The light is set to produce money, and it is suitable to provide the light of the same color with the light of the color and the corresponding relationship between the colors of the elements. The special training system can be adjusted to make the light form - how much is the temple? 5 light source. The photosensitive devices and the halogen patterns are in the system and are electrically connected to the detecting device, and the photosensitive devices are located on the same side of the color filter as the device. Wherein, after the plurality of halogen patterns of the light source are combined, respectively, the photosensitive devices of the plurality of reflected light grains are respectively received by the photosensitive device, and the reflected signals are converted and transmitted to the detecting device to turn off the (four) side sample.

Another purpose of this is to provide a detection system for another color filter, which is capable of effectively detecting the penetration plague of the color appearing through the light. The color light-receiving sheet comprises a plurality of layers having different colors. The gold measuring system comprises a detecting device, a detecting light generating device and a complex detecting device. Detecting a light generating device, which is suitable for providing a plurality of different colors, and at least some of the light is in a color corresponding to the color patterns, and the light between the lights is extinguished The light has to form a two-dimensional temple = the age of the fresh spectrum.

The other objects of the present invention, the technical means and embodiments of the present invention will become apparent to those skilled in the art of the invention. [Embodiment] As shown in Fig. 2(a), the first embodiment of the present invention relates to a detection system 20 for detecting reflected light on a color filter 21. For convenience of description, only the basic composition of the red color 211, the green 212, and the blue 213 triterpenoid pattern on the color filter 21 is exemplarily illustrated, and the figure is only for the representative figure and is not drawn according to its true scale. . Preferably, the detection system 20 includes a detection device (not shown), a light guide plate 22, a detection light generating device, and three photosensitive devices.

The two initial light sources, that is, the red light source 241 and the green light source 2, and the light source 243 are combined with three photosensitive devices, that is, the red photosensitive device 251 device 252 and the blue photosensitive device 253 are taken as an example to illustrate ❶ ^ 253 and The pixel patterns 211 to 213 are in color system and the detecting device is electrically connected to the photosensitive device 251 to attack. In the example, the photosensitive devices 251 to 253 and the detection light generating device (light source 24^243) are disposed in the same color as the color light-emitting sheet 21; the two sources 241 to 243 provide three incident light rays, respectively red light. The green light is not shown in the figure. The three incident light rays are incident on the light guide plate 22 after the frog mirror device is adjusted to a specific relationship to form a hybrid light source 27. 1322888 'Patent Application No. 095113834 Replacement (without scribe version, April 1998) Γ 2 3 Sources • Essentially - white light source, only red, green and blue = 22 spectrum has been - Special (4), so that the gray ash reflected from the color 先 first film to be detected is very similar or even equal.

Therefore, the red light, the green light, and the blue light are emitted by the human being in the light guide. After the optical guidance of the special light, the hybrid light source 27 is formed. The mixed light source 27 is incident on the color filter 21. In detail, after the hybrid light source 27 is incident on the pixel patterns 2111213 of the color light-passing sheet 21, a plurality of reflected rays 29a and 2% are respectively generated. 29c, which is a first value, a second value, and a third value corresponding to the red 211, green 212, and blue 213 trichromatic enamel patterns, which are received by the respective photosensitive devices 251 to 253, and The reflected signals generated by the reflected rays 29a, 29b' 29c are transmitted to the detecting device to determine whether the pixel patterns 211 to 213 have reflections. - Again, the three initial light sources are used in addition to the red light source 241, green.

In the first embodiment, if the examiner wants to detect the reflected signal, the photosensitive devices 251 to 253 are disposed on the same side of the color filter 21 as the light guide plate 22. In the second real case, the 'right inspection' is that the person needs to know the detection result of the mixed light source transmitted through the color filter and the light sheet. In this case, the detecting person can set the photosensitive devices 251 to 253 with respect to the colored tear film 21 On the opposite side of the light guide plate 22. Therefore, after the mixed light source 27 is incident on the pixel patterns 211 to 213 in the color filter 21, a plurality of penetrating rays 30a, 30b, and 30c are respectively generated, and the corresponding photosensitive devices 251 to 253 are respectively generated. Receiving and converting into a transmission signal to be transmitted to the detecting device (not shown to determine whether the pixel patterns 211 to 213 have penetration fatigue. The remaining component configurations and their functions in the second embodiment are the first The embodiments are similar, and are not described herein. The basic steps of the method for detecting the color filter of the present invention are as follows: a small portion of the light rays are in a color correspondence with the two prime patterns; The fresh 绮 ' and (4) light forms a mixed light source of the $ characteristic frequency spectrum; /, n mixed light source is injected into the book patterns of the color light film to respectively generate a plurality of corresponding 峨; and ^ The pattern is set to 'receive the signals and pass them to the plural pairs to be similar or even scales, and to touch the side of the sample. 12 Patent No. 095113834 Replacement of the patent application (no f-line version, 98 years) April) In the step of t), It can be received by a filter - receiving a mixed light source that is converted into a complex color of different colors, and is not suitable for use with the original light. It can also be loaded with the frog mirror to go to the autumn, and more A plurality of initial sources are placed to form the desired hybrid source. Two sources to enhance the brightness of the hybrid light source. The frequency spectrum of the (9) ί specific frequency c is adjusted such that the light forms a mixed light source with a h, and the gray level value of the reflected light or the transmitted light is even substantially the same. In the step (c), if the plurality of corresponding light-exposed S-systems are from the mixed light source, the light-emitting beams are incident on the color light-emitting sheet, and the light is reflected light. In other words, In step (C), a corresponding light is read, and the silk is simply inserted into the color from the mixed light. After the m-shaped pattern is first transmitted, the light is transmitted through the pupil. The device 'converts the received reflected light, or the tooth-through line' into a reflected signal or a penetration signal, and transmits it to the detection device to detect the broken wire or the transmissive level. The reading value is similar or even The same, and determine whether the enamel patterns are flawed. Hyun will further explain the steps of the actual detection as follows. As mentioned above, the process of attaching the color to the film is generally based on red, green and blue. The pattern is sequentially placed on the glass substrate' and the sequence is attached. The latter will also affect the former's already attached & finished microscopic pattern. In more detail, the green alizarin pattern will be attached. Causes the appearance of the red pixel pattern; attaches the blue pixel pattern, It may cause red and green enamel patterns to appear again. Therefore, each time a color enamel pattern is pasted, the fatigue detection work of the above-mentioned color enamel patterns containing the color can be performed. Now = an actual experimental example Description: For the penetration 瑕疵 detection of penetrating light, if the traditional white light vehicle is used to illuminate the color, it will pass through the red, green and blue enamel patterns of the color filter. Subsection No. 095丨13834 Patent Application Specification Replacement (No j彳 line version, April 1998) 133, 168, 144 ' Because the gray scale value is not uniform, it produces a month.,., staff comparison, otherwise瑕疵That is, it is difficult to detect in each book f.

Since it can produce a consistent value with the value of 9〇, it is said that the thief is profitable, the material is sensed similarly, and the reflection of the reflected light is recorded by the J light film, and the reflected color light film is reflected. Color, ▲ after the color pattern, presented The grayscale values are 232, 15b, respectively, because their grayscale values are also non-uniform, so there are "black owes" or "over", unless their grayscale values are compatible with the grayscale values of all the tilde patterns.匕 疵 疵 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 难以 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; The grayscale values of the different color schemes of the different colors are close to 11〇, so “black owe” = “white owe”, because the positive value I can be consistent with the value of 110; Therefore, it can be easily detected by the sensing device regardless of whether it is obvious or not.
