  • Patent number: 12009464
    Abstract: A display device includes a pixel array substrate and a circuit board. The pixel array substrate has a first surface, a second surface opposite to the first surface, and a first side surface connecting the first surface and the second surface. Multiple bonding pads are located on the first surface. The circuit board is bent from above the first surface of the pixel array substrate to below the second surface. The circuit board is electrically connected to the bonding pads and includes a thermoplastic substrate. The thermoplastic substrate includes a third surface facing the pixel array substrate and a fourth surface opposite to the third surface. The thermoplastic substrate includes a first bend formed by thermoplastics.

  • Publication number: 20240188306
    Abstract: A resistive memory device includes a dielectric layer, a first via connection structure, a first stacked structure, and a first insulating structure. The first via connection structure is disposed in the dielectric layer. The first stacked structure is disposed on the first via connection structure and the dielectric layer. The first insulating structure penetrates through a portion of the first stacked structure in a vertical direction and divides the first stacked structure into a first cell unit and a second cell unit. The first cell unit and the second cell unit include a first shared bottom electrode, and the first insulating structure is disposed directly on the first shared bottom electrode.

  • Patent number: 7555697
    Abstract: A data error-detecting method for detecting errors before C1 decoding procedure is provided. First, a bit modulation is performed for modulating data channel bits obtained from an optical disk into 8-bit data. When the data channel bits is determined to introduce a legal mapping, an erasure bit having a first value is derived and tagged at the modulated 8-bit data, otherwise an erasure bit having a second value is derived and tagged at the modulated 8-bit data. After the 8-bit data being arranged as a codeword composed of 32 erasure bits respectively tagged with 32 8-bit data, counting the number of the modulated 8-bit data tagged with the erasure bit having the second value. When the counted number is less than 4, the codeword composed modulated 8-bits data tagged with the erasure bits having the second value can be corrected.
