The present invention provides a glass substrate for flat panel display in which yellowing occurring in a case of forming silver electrodes on glass substrate surface is inhibited. A glass substrate for flat panel display, which is formed by a float method, which has a composition consisting essentially of, in terms of oxide amount in mass %: wherein the average Fecontent in a surface layer of the glass substrate within a depth of 10 &#x3bc;m from the a top surface is at most 0.0725% in terms of FeOamount.

Glass substrate for flat panel display, process for producing the same, and display panel employing the same

Glass having low solar radiation and ultraviolet ray transmittance, which consists essentially of a soda lime-silica type matrix glass containing from 0.53 to 0.70 wt % of total iron calculated as Fe.sub.2 O.sub.3, from 0.2 to 0.4 wt % of TiO.sub.2 and from 0.5 to 0.8 wt % of total cerium calculated as CeO.sub.2, wherein the weight of FeO calculated as Fe.sub.2 O.sub.3 is from 30 to 40% of the weight of the total iron calculated as Fe.sub.2 O.sub.3.

Stored in a two-dimensional memory is a read-in character information of one character which was scanned by an optical scanner and digitized into character digital bits and background digital bits. The character information on the storage plane of the memory is divided into a plurality of segments using 4.times.4 bit meshes as a unit and the number of the character digital bit meshes included in each of the segments is counted. A collection of segment information obtained from these count values is used as an input information and is compared by pattern matching with each of a collection of standard character information preliminarily prepared for a set of characters in the same information form as the input information, thereby effecting the desired type font character recognition.
