摘要： A field emission type display device capable of providing display with gradation and permitting the whole display device to be integrated with a display drive circuit section. Memory sections are arranged in correspondence to image cell sections, resulting in static display being accomplished. Also, Light emission of an anode is carried out depending on data held in the memory section, so that a luminous period is increased and adequate luminance is provided at a drive voltage substantially lower than that required for dynamic display. An FEC element is incorporated in each of the memory sections in correspondence to incorporation of an FEC element in each of the image cell sections, so that the image cell sections and memory sections may be concurrently manufactured during manufacturing of the FEC elements, to thereby significantly simplify manufacturing of display device.

摘要： A display-integrated tablet device capable of improving luminance of an image displayed while carrying out coordinate detection plural times during a one-image-plane display period. X-coordinate detection is carried out in a manner to take, in an X-coordinate detection section, a voltage obtained by feeding each of second gate electrodes with a pulse generated in a pen-pulse generation circuit. Y-coordinate detection is carried out by inputting a voltage obtained by outputting of a pulse for scanning Y-electrodes (lines) from a stylus pen to a Y-coordinate peak detection circuit. After coordinate detection is thus executed, only Y-electrodes in a predetermined range about a Y-coordinate previously detected are scanned in a Y-coordinate detection period provided after each of block display periods defined by dividing an image display period.

摘要： A light-amount correction dynamic range expanding device that can increase the number of exposure gray levels without increasing the memory capacity of the storage section for light-amount correction. Input data is formed of (n+k) bits to increase exposure gray-scale level. A first look-up table stores the output densities to the number of exposure gray levels for photosensitive substances classified by photosensitivity. Of (n+k) bits output from the first table, a first selector selectively outputs only effective n bits to a second table 2 to use m bits needed for a photosensitive substance. The second look-up table stores brightness information to correct variations in brightness between luminous dots of a print head, with a memory capacity of n bits. A FIFO memory temporarily stores the brightness information. A selector 2 again converts the output from the FIFO memory into a (n+k)-bit form and ten it to a gray-scale control means. The gray-scale control means controls the gray scale of the print head with the (n+k) bit data, so that the brightness variation is corrected with n-bit data and with necessary and sufficient accuracy.

摘要： An electron gun and a CRT capable of accomplishing a reduction in spot diameter of electron beams, an increase in drive speed and control of luminance while being simplified in structure. Field emission cathodes acting as the electron source for the electron gun are arranged in the form of or divided into plurality of the small regions S for matrix driving, to thereby control luminance of the CRT depending on the number of small regions S selected. Thus, luminance control over any desired number of gradations which exhibits satisfactory resistance to noise and linearity can be realized while simplifying the structure, resulting in the field emission cathodes being highly conveniently applied to the electron gun of the CRT, leading to an improvement in functionality of the CRT.
