Publication number: 20240169939Abstract: Provided are LED-display-screen drive chip and LED display screen, wherein the drive chip is configured such that: when a grayscale value R of a grayscale data is less than or equal to Q, the grayscale data is allocated to one display group in M display groups; and when the grayscale value R of the grayscale data is larger than Q, the grayscale value of one display group of the M display groups is P, wherein P>=Q, and a total grayscale value of remaining M?1 display groups is R?P, wherein in display groups in the remaining M?1 display groups whose grayscale value is not 0, a number of display groups whose grayscale value is less than L is not more than 1, wherein L?1, Q>L, and Q is a centralized display threshold. The present disclosure is capable of making the low-grayscale display effect smoother and improving the display effect.Type: ApplicationFiled: October 30, 2023Publication date: May 23, 2024Inventors: Yongsheng TANG, Shilin SHEN, Aqiang LIU, Shixiong LU

Publication number: 20240112624Abstract: Provided are decoupling circuit, driving IC, and display device. The decoupling circuit includes pre-charging module and constant current driving module, an output terminal of the pre-charging module and an output terminal of the constant current driving module are connected together to serve as a channel output terminal; within one display unit, when PWM is greater than 0, operation states of the pre-charging module are pre-charging V1, pre-charging off, and pre-charging V2 in sequence, the constant current driving module is turned on based on PWM in stage of the pre-charging off, such that a lamp bead is lit, and at this time, voltage at the channel output terminal is V3; when the PWM is equal to 0, the constant current driving module is turned off, and output states of the pre-charging module are pre-charging V4, pre-charging V5, and pre-charging V6 in sequence, (V1?V3)?(V4?V5)=K1, (V2?V3)?(V6?V5)=K2, K1 and K2 are constants.Type: ApplicationFiled: August 28, 2023Publication date: April 4, 2024Inventors: Yongsheng Tang, Li Huang, Shilin Shen, Aqiang Liu

Patent number: 11923127Abstract: The present disclosure relates to a tank of a high-voltage generator including a tank body and a tank lid. There is an opening in the tank lid. The opening is connected to the bellows so as to counteract the volume change of the transformer oil and avoid generation of bubbles. The tank includes a positive transformer, a negative transformer, a bellows, and other components. The high-voltage winding is embedded in the PCBs. The outer insulating bushing is covered by the PCBs so as to improve the insulativity between the turns of the high-voltage winding. In addition, oil barriers may be placed between the positive and the negative transformers, or between the transformers and the ground so as to eliminate the bridge breakdown effect and make the electric field uniform. By means of said measures, the present disclosure improves the stability of the high-voltage generator.Type: GrantFiled: November 2, 2020Date of Patent: March 5, 2024Assignee: SHANGHAI UNITED IMAGING HEALTHCARE CO., LTD.Inventors: Yunhua Zhang, Jieyong Meng, Qingchang Chen, Yihong Liu, Shilin Shen
