Title: Device and method for detecting changed line
Inventor: ARAYA SHUNTARO
IPC: G09G3/36
Filed: 1994-07-04
Abstract: PURPOSE:To detect changed line by performing comparison between frames with a small amount of memory. CONSTITUTION:Pixel data coming from a color LUT in the form of 8bitsX4 are latched by a latch 51 and 32bit data and 0 are added with an adder 52. The rotate-shift by one bit of the obtained 64bit date is performed by a rotate shift register 53 and the shifted data are added to next 32bit date. After this addition is repeated for a fixed time, values of the rotate shift register 53 are compared as a 'Signature' with the 'Signature' of the same place as a front frame. A comparator 54 outputs Result=1 in the case Signatures are different and outputs Result=0 in the case Signatures are equal. At this time, the count value of the number of lines of a timing control part 55 is simultaneously outputted. The Signature date of a present frame are stored in a memory 46 for the comparison with next frame.

Abstract: PROBLEM TO BE SOLVED: To obtain the liquid crystal display device of superior display quality without using any slit light shield mask by hardening a sealant by irradiation with light whose specific wavelength range of ultraviolet rays decomposing or deteriorating a liquid crystal composition is cut. SOLUTION: When the liquid crystal composition 5 is injected into a liquid crystal cell 3 and the sealing hole 4 is hardened with the ultraviolet-ray setting sealant 6, an optical fiber type ultraviolet-ray lamp 9 is used.

At this time, the optical fiber type ultraviolet-ray lamp 9 such light emission wavelength spectrum characteristics that the light emission of the ultraviolet rays 7 is less in the short-wavelength range than in any other wavelength range.  Consequently, the liquid crystal composition 5 which is decomposed or deteriorated owing to irradiation with the ultraviolet rays 7 in the short-wavelength range can be prevented from being decomposed or deteriorated in the hardening process of the sealant 6 by irradiating the sealant with the ultraviolet rays through the optical fiber 9a which is small in the propagation of the ultraviolet rays 7 in the short-wavelength range.
