20150042233 | LED Backlight Driving Circuit and LCD - The present invention proposes an LED backlight driving circuit comprises voltage booster circuits parallelly connected and a constant current driving IC module. The voltage booster circuits are used for conversing an input voltage into a needed output voltage to supply to an LED unit. The constant current driving IC module is used for controlling the voltage booster circuits, so that the voltage booster circuits converse the input voltage into the needed output voltage to supply to the LED unit, driving the LED unit in a constant current. The constant current driving IC module generates driving signals at different frequencies to control the voltage booster circuits respectively. The invention can set up multiple driving signals operating simultaneously at different frequencies respectively and disperse resulting harmonic wave, hence reduce EMI signals of the backlight driving circuit effectively. The present invention also proposes an LCD using the LED backlight driving circuit. | 02-12-2015 |
20140146442 | Display Device - A display device is proposed. The display device includes a frame, a back plate, a display panel, a flexible printed circuit board, and a tape. The frame is assembled to the back plate to form an accommodation space. The display panel, is disposed in the accommodation space and situated on top of the back plate. The flexible printed circuit board is stuck to and electrically connected to the display panel. The tape includes a first portion and a second portion. The first portion of the tape is disposed opposite the flexible printed circuit board on the display panel. The second portion of the tape is disposed between an edge of the display panel and a side wall of the frame. Therefore, light is prevented from being leaked from the display panel and the flexible printed circuit board is protected against being scratched in the present invention. | 05-29-2014 |
20140064884 | Oven and Adjustable Baking System - An oven and an adjustable baking system are proposed. The oven includes a signal receiving module, a baking module, a detecting module, and a feedback module. The signal receiving module is used for receiving a ready-to-send signal sent by a developing apparatus in a previous process from the oven. The ready-to-send signal conveys information of preparing for transferring a glass substrate to the oven. The detecting module is used for detecting the robot to see if the robot takes the glass substrate out of the baking module. The feedback module is used for determining if a confirmation signal is sent back to the developing apparatus according to the detecting result from the detecting module. The confirmation signal conveys information that the developing apparatus should transfer the glass substrate to the feedback module. Because the transferring speed of a glass substrate transferred by the developing apparatus can be adjusted in the oven and the adjustable baking system of the present invention, no buffers are required, reducing equipment costs. In addition, the baking time of the oven is adjusted, which increases efficiency of baking | 03-06-2014 |
20140021408 | LIQUID CRYSTAL MEDIUM COMPOSITION OF LIQUID CRYSTAL DISPLAY - A liquid crystal medium composition of liquid crystal display includes: a negative liquid crystal material, reactive monomer, an initiator, and a stabilizer. The initiator functions to induce photo polymerization of the reactive monomer. The initiator has a molecular structure comprising aromatic rings, carbonyl groups connected to the aromatic rings, and substituted moieties connected to the aromatic rings. The initiator lowers the activation energy of chain initiation reaction of the polymerization of reactive monomer to allow the photo polymerization of the reactive monomer to take place in a wider wavelength range of 200-450 nm, so as to reduce the required intensity and luminance of ultraviolet light and to speed up the reaction of the reactive monomers and also to provide a uniform result of reaction, to reduce the destruction that the ultraviolet light causes on the material of alignment layer and the liquid crystal material, and to improve stability of the panel. | 01-23-2014 |
