  • Publication number: 20240135745
    Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

  • Patent number: 11966628
    Abstract: A memory device, includes a memory array for storing a plurality of vector data each of which has an MSB vector and a LSB vector. The memory array includes a plurality of memory units each of which has a first bit and a second bit. The first bit is used to store the MSB vector of each vector data, the second bit is used to store the LSB vector of each vector data. A bit line corresponding to each vector data executes one time of bit-line-setup, and reads the MSB vector and the LSB vector of each vector data according to the bit line. The threshold voltage distribution of each memory unit is divided into N states, where N is a positive integer and N is less than 2 to the power of 2, and the effective bit number stored by each memory unit is less than 2.

  • Patent number: 11955469
    Abstract: A micro LED display panel includes a blue LED layer, a green LED layer, and a red LED layer. The blue LED layer, the green LED layer, and the red LED layer are in a stacked formation. The blue, the green, and the red LED layers each include a plurality of micro LEDs spaced apart from each other. The composition of the layers is such that light emitted from all but the bottom layer is able to pass through transparent material in other layers before exiting the panel and being viewed.

  • Patent number: 5799207
    Abstract: A computer system is disclosed which has a master, such as a processor, a memory, and I/O device, a first transfer path, which includes a bus, and a second transfer path, which includes a transfer interconnection. Transfers between the memory and the I/O device are effected via the first path while transfers between the processor and the I/O device are transferred via the second path. The disparate treatment between these two types of transfers reduces the likelihood that the transfer via the second path is delayed and thereby reduces the likelihood that the master is totally blocked from operation.

  • Patent number: 5623635
    Abstract: A method and system is disclosed for efficiently transferring a sequence of data words from an I/O device to sequential addresses in a main memory via an I/O bridge. The sequence of data words to be transferred includes one or more subsequences of data words. Each subsequence of data words include only data words destined to addresses of the main memory in which data words of only one data line are stored. The I/O bridge has control logic for receiving a first subsequence of data words corresponding to a currently owned data line and for claiming ownership in one or more of the very next data lines corresponding to the next subsequences of data words to be transferred from the I/O device. The I/O bridge also has a buffer memory for storing a subsequence of the sequence of data words received from the I/O device.

  • Patent number: 5615334
    Abstract: A memory reflection scheme is disclosed including a snarfing agent provided with efficient memory reflection circuitry for snarfing data. The memory reflection circuitry is for snarfing particular data written back from a write back agent to a memory subsystem agent. In response to unsuccessfully snarfing the particular data written back from the write back agent to the memory subsystem agent, the memory reflection circuitry issues a command to read the particular data from the memory subsystem agent. However, the memory reflection circuitry only issues such a command if the write back agent successfully writes back the particular data to the memory subsystem agent.
