20110013132 | LCD PANEL AND METHOD OF MANUFACTURING THE SAME - A liquid crystal display (LCD) panel, comprising a first substrate and a second substrate assembled face to face, each having a display area and a peripheral area around the display area, liquid crystal, and sealant formed between the peripheral area of the first substrate and the peripheral area of the second substrate. On the first substrate, at least one first obstructing frame is formed between the sealant and the display area of the first substrate; on the second substrate, at least one second obstructing frame is formed between the sealant and the display area of the second substrate; the first obstructing frame and the second obstructing frame are disposed at an interval and parallel to each other; each of the first obstructing frame and second obstructing frame has a thickness smaller than a cell gap, and a sum of the thicknesses of a pair of the first obstructing frame and second obstructing frame that are adjacent to each other is greater than the cell gap. | 01-20-2011 |
20140057200 | METHOD FOR PRODUCING MASTERBOARD ALIGNMENT FILM AND TRANSFER PRINTING PLATE AND ALIGNMENT SOLUTION - Embodiments of the present invention disclose a method for producing a masterboard alignment film, and a transfer printing plate and an alignment solution. The method comprises coating the alignment solution on a masterboard having two or more substrates using the transfer printing plate which has a transfer region simultaneously covering the two or more substrates, so that the alignment solution forms an alignment film on the masterboard; and removing the alignment film on the masterboard which is located in regions that are out of the display regions of the substrates and where there is no need to retain the alignment film. This method can solve the existing display defect issues that are caused by too thick peripheral regions of the alignment film, and the overlapping of the too thick peripheral regions of the alignment film with the sealant region. | 02-27-2014 |
20140212019 | METHOD FOR DETECTING ALIGNMENT FILM AND DEVICE FOR THE SAME - The embodiments of the present disclosure provide a method for detecting alignment film and device for the same. The method comprises: obtaining an image of an alignment film test region of a substrate; and analyzing continuity of the alignment film along an internal boundary of the alignment film test region in the image obtained. since the alignment film test region is located outside an active display area of the substrate, when the alignment film along the internal boundary of the alignment film test region is determined as continuous, it can be determined that all the edges of the alignment film are outside the active display area, then a Haro region which might appear on the edge of the alignment film may also be located outside the active display area, so as to ensure uniform thickness of the alignment film in the active display area of the substrate. | 07-31-2014 |
20140240648 | LIQUID CRYSTAL PANEL AND FABRICATING METHOD THEREOF AND DISPLAY - Embodiments of the present invention relate to a liquid crystal panel and a fabricating method thereof and a display. The liquid crystal panel comprises: an array substrate and a color filter substrate bonded by a first sealant, with a region surrounded by the first sealant between the array substrate and the color filter substrate forming a liquid crystal panel display region filled with liquid crystal. In addition, the liquid crystal panel further comprises: a liquid crystal buffer region, located at the outer side of the first sealant; a liquid crystal channel, through which the liquid crystal buffer region and the liquid crystal panel display region are connected; and a covering layer, covering at least a position where the liquid crystal channel connects with the liquid crystal panel display region. | 08-28-2014 |
20150108672 | DEVICE AND METHOD FOR ADJUSTING POST-SPACER HEIGHT IN PRODUCTION OF LIQUID CRYSTAL DISPLAYS - A device and a method for adjusting post-spacer height in production of liquid crystal displays (LCDs), and the device comprises a controller ( | 04-23-2015 |
20150217324 | ALIGNMENT FILM PRINTING DEVICE - An alignment film printing device, configured to improve coating quality of an alignment film, includes at least one printing unit, and the printing unit each includes: a cylinder body with an opening at a bottom and an extract opening on a top; a vacuum extractor connected with the extract opening; a plunger provided inside the cylinder body, and configured to draw the alignment fluid from the opening to the cylinder body; a vacuum tester provided at the extract opening and configured to monitor a vacuum degree inside the cylinder body and above the plunger; a range finder provided inside the cylinder body and configured to monitor a distance from the plunger to a top of the cylinder body; and a control device in signal communication with the vacuum extractor, the vacuum tester and the range finder respectively and configured to control a volume of the alignment fluid drawn into the cylinder body according to test values of the vacuum tester and the range finder. | 08-06-2015 |
20150331271 | POST SPACER AND DISPLAY SUBSTRATE - Disclosed is a post spacer and display substrate, a cross section of the post spacer in the direction perpendicular to the height direction comprising a first portion that is symmetrical with respect to an axis in a first direction, the maximal width of the first portion in a second direction perpendicular to the first direction being the maximal width of the whole cross section in the second direction, and the width of the first portion decreasing progressively along the first direction, wherein a shape between a vertex of the first portion in the first direction and each of the two endpoints defining said maximal width is a straight line, and an included angle between both straight lines is less than or equal to 90 degree, or a shape between a vertex of the first portion in the first direction and each of the two endpoints defining said maximal width is a convex arc, an included angle between both straight lines connecting respectively the vertex to each of the two endpoints is less than or equal to 90 degree, and the convex arc is different from the circular arc on a circle with the straight line segment connecting the two endpoints being the diameter thereof. | 11-19-2015 |
20150362767 | Liquid Crystal Panel and Manufacturing Method Thereof, and Display Apparatus - The present invention provides a liquid crystal panel and a manufacturing method thereof, and a display apparatus comprising the liquid crystal panel, which relates to the field of display technology, and can avoid the problem that the sealant is separated from the first substrate and/or the second substrate while the liquid crystal panel is bent. The liquid crystal panel of the present invention comprises a first substrate and a second substrate, the first substrate and the second substrate are aligned with each other to form a liquid crystal cell, and the liquid crystal cell is sealed with sealant, wherein, at least one convex structure is provided in a region which corresponds to position of the sealant on the first substrate and/or the second substrate. | 12-17-2015 |
